Mount Athos Pilgrimage: The Rules

1. What Mount Athos Is

Mount Athos is the easternmost of the three fingers of land that reach south from Chalkidiki into the northern Aegean, and the whole of that finger belongs to Orthodox monasticism. Twenty ruling monasteries divide the entire peninsula between them, govern it jointly from a small inland settlement called Karyes, and admit visitors on their own terms under their own written permit. Greeks call the place Agion Oros, the Holy Mountain, and in ordinary Greek usage that name covers the peninsula, the government and the monastic community all at once.

Nothing on the peninsula exists outside that arrangement. There is no town in the ordinary sense, no municipality, no private landowner, no resident family, no hotel, no shop that is not a monastic dependency. Karyes has an administrative building, a church, a handful of workshops and stores serving the houses, a police post and a small clinic, and it is a village only in the sense that a monastery has a courtyard. Everything else on the peninsula is a monastery, a skete, a cell, a hut, a hermitage on a cliff, a chapel, a mule track or a forest.

The consequence for a visitor is simple and worth stating early. A trip to Athos is an application to be received as a guest inside a working monastic enclosure that happens to be the size of a small county. The permit, the cap on numbers, the closed gates at sunset, the men-only rule and the dress code all follow from that one fact, and they make sense as soon as the enclosure is taken seriously.

Mount Athos was inscribed on the World Heritage List in 1988 as a mixed cultural and natural site. The inscription and its rationale are published by the UNESCO World Heritage Centre.

2. The Peninsula and the Mountain

The Athonite peninsula runs roughly fifty kilometres south east into the Aegean and is only a few kilometres wide along most of that length, ending in a bare marble peak that rises just over two thousand metres straight out of the sea. The mountain gives the whole territory its name. Seen from a boat on a clear morning it dominates everything, and from the summit chapel of the Transfiguration on the top the peninsula reads as what it is, a ridge of forest and rock with buildings clinging to its edges.

The land boundary and why everyone arrives by sea

Athos is joined to the mainland by a narrow isthmus at its northern end, and that isthmus is the legal frontier of the self-governing territory. No public road crosses it. Visitors reach the peninsula by boat, sailing down the west coast from Ouranoupoli or down the east coast from Ierissos, and the boat is the only ordinary way in. The sea can close the route for a day at a time in bad weather, which is one of the reasons an Athonite schedule is held loosely.

The isthmus has a long memory of its own. Herodotus records that Xerxes had a canal cut across it before the invasion of Greece in 480 BC, so that the Persian fleet could avoid the storms that had wrecked an earlier expedition rounding the Athos headland (Herodotus, Histories 7.22 to 7.24). Traces of the cut are still visible in the ground across the neck of the peninsula.

Geography that shapes the monastic life

The two coasts are different countries in miniature. The western side is gentler, with the larger houses set on slopes above small harbours. The eastern and southern flanks are steeper, and the closer you get to the peak the harsher the ground becomes, which is exactly why the strictest ascetics live there. The cliffs at the southern tip, in the district called Karoulia, hold hermitages reached by chains and cut steps, occupied by monks who have chosen the hardest available terrain on purpose.

Between the houses the connections are old stone mule paths, many of them medieval, and walking them is still the classic way to move between monasteries. A network of unpaved tracks now carries vehicles for supplies, and small boats run along the coast, but the paths remain the spine of the place.

3. Why Athos Is Called a Monastic Republic

Athos is called a monastic republic because the twenty monasteries govern the territory collectively through an assembly of their own representatives, under a written constitution of their own drafting. The arrangement is genuinely a government: it legislates for the peninsula, runs its courts of first instance in monastic matters, controls entry, and holds all the land in common through the twenty houses.

The Charter

The governing instrument is the Constitutional Charter of Mount Athos, drawn up by the Athonite community itself in 1924 and given force in Greek law by ratification in 1926. The Charter fixes the number of ruling monasteries at twenty, forbids the founding of a twenty-first, forbids the dissolution of any of the twenty, and forbids the alienation of Athonite land. It also confirms the rule barring women and sets out how the community governs itself.

The Holy Community and the Holy Epistasia

Day to day government belongs to the Holy Community, the Hiera Koinotis, which sits at Karyes and consists of twenty representatives, one sent by each ruling monastery and replaced on a regular cycle. The Community deliberates as a body and its decisions bind the peninsula.

Executive work falls to a smaller committee called the Holy Epistasia, made up of four members drawn from four monasteries at a time. The twenty houses are grouped into five sets of four, and the sets take the Epistasia in turn, so that every monastery has a share of the executive office within a five year cycle. The senior member of the serving Epistasia is called the Protepistatis, and the office carries precedence rather than personal power, since the four act together and hold the seals of the Community between them.

Grave questions go to a larger body, the Extraordinary Double Synaxis, which brings together the abbots and the representatives of all twenty houses. Matters touching the Charter, relations with the Greek state, or serious discipline are settled at that level.

The Greek state on the peninsula

A civil governor appointed by the Greek Ministry of Foreign Affairs resides at Karyes and represents the state. His role is to see that Greek law is observed and the Charter respected, with a small police detachment and customs and postal functions alongside. Greek criminal law applies on Athos in the ordinary way. The governor does not run the monasteries and cannot overrule the Holy Community on internal monastic matters.

4. Who Athos Answers To

Mount Athos answers ecclesiastically to the Ecumenical Patriarchate of Constantinople and constitutionally to the Greek state, and the two lines are kept separate on purpose. Article 105 of the Greek Constitution recognises the Athonite peninsula as a self-administered part of the Greek state whose spiritual jurisdiction belongs directly to the Ecumenical Patriarchate.

The practical effect is that Athos does not belong to the Church of Greece, even though it sits inside Greek territory and most of its monks are Greek. The Patriarch of Constantinople is commemorated by name in the services of the Athonite houses, exarchs are sent from the Patriarchate for canonical business, and the appointment and discipline of abbots run back to Constantinople rather than to Athens. Readers who want the wider picture of how the Orthodox churches are organised into self-governing bodies can start with our guide to the autocephalous Orthodox churches and how they relate.

The Athonite houses and their national traditions

Athos has always been international within Orthodoxy. Hilandar is the Serbian house, founded at the end of the twelfth century by Saint Symeon and his son Saint Sava and central to Serbian religious identity ever since. Zographou is Bulgarian. Saint Panteleimon, often called Rossikon, is the Russian house. Iviron was founded by Georgians and carries a Georgian name to this day, though its brotherhood has long been Greek. The others are Greek houses, and the working language of the Holy Community is Greek.

Where the reserve toward Rome comes from

Athonite houses are, as a group, theologically conservative, and several of them have publicly criticised meetings between Ecumenical Patriarchs and Popes. That position deserves to be stated in its own terms. The Athonites hold that the divisions between Rome and the East are doctrinal, that the Roman claims about papal jurisdiction and the addition of the Filioque to the Creed are genuine departures, and that friendly gestures which leave those questions unresolved risk suggesting a unity that does not exist. Our page on the Filioque and why the Creed still divides East and West sets out that argument and the Catholic reply.

The sharpest expression of Athonite reserve is the long dispute at Esphigmenou, whose brotherhood broke commemoration of the Ecumenical Patriarch in 1972 over his ecumenical contacts. The Patriarchate declared that brotherhood schismatic and recognised a replacement brotherhood for the monastery, and the resulting quarrel over the buildings has run through Greek courts for decades. The dispute is real, it is unresolved in its details, and any account of the current state of the buildings goes out of date quickly.

5. The Twenty Ruling Monasteries

Twenty ruling monasteries hold Mount Athos, and they are always listed in a fixed hierarchical order that has nothing to do with size or wealth. The order reflects historical precedence, it governs seating and voting sequence in the Holy Community, and Athonites use it as naturally as other people use an alphabet. Great Lavra stands first because Saint Athanasios the Athonite founded it in 963 with the support of the Emperor Nikephoros II Phokas, and Stavronikita stands twentieth because it was the last of the twenty to be established, in the sixteenth century.

Cenobitic and idiorrhythmic

Athonite houses have historically followed one of two patterns. A cenobitic monastery holds everything in common under an abbot elected for life, with a common table, a common purse and a common schedule. An idiorrhythmic monastery allowed monks to keep their own property, manage their own food, and follow a personal rhythm, under a committee of elders rather than an abbot. The idiorrhythmic pattern spread on Athos during the difficult centuries and was widely regarded inside the monastic tradition as a concession to hard times. Every one of the twenty follows the cenobitic pattern today, the last of the idiorrhythmic houses having returned to common life during the twentieth century.

The return of the twenty to common life belongs to a wider recovery. Athonite numbers fell steadily through the nineteenth and earlier twentieth centuries, several houses came close to emptying, and from the 1960s and 1970s onward whole brotherhoods of younger monks moved in from elsewhere in Greece and repopulated houses that had been down to a handful of elderly men. Comparable renewals of monastic life on rock and mountain sites can be seen in our guide to the Meteora monasteries in Thessaly.

6. Sketes, Cells and Hermitages

Only twenty houses rule Athos, and a great many more monks live outside them in smaller settlements that all belong legally to one of the twenty. The vocabulary matters, because visitors often assume a skete is a small monastery with an independent existence, and no such thing exists on the Holy Mountain.

The four kinds of dependency

A skete is a monastic village dependent on a ruling monastery, with a central church called the kyriakon where the community gathers on Sundays and feasts. Cenobitic sketes live a full common life under a superior appointed with the ruling monastery's agreement. Idiorrhythmic sketes are scattered houses whose small groups keep their own rhythm most days and come together at the kyriakon.

A kellion is a cell, in practice a small farmhouse with a chapel, holding a few monks who work the ground around it. A kalyve is a hut, smaller again, often without land. A hesychasterion is a hermitage proper, a place chosen for solitude, sometimes little more than a cave with a built face.

At the extreme southern end, in Karoulia and Katounakia, hermits live on the cliffs above the sea in dwellings reached by chains, ladders and cut steps. That district is the ascetic edge of Athos, and its inhabitants have chosen an austerity that most of the monks in the ruling monasteries would describe as beyond them.

Everything belongs to one of the twenty

Every skete, cell, hut and hermitage stands on land owned by one of the twenty ruling monasteries and holds it by a written grant. A hermit on a cliff at Karoulia is a tenant of a monastery, subject to its abbot, and his dwelling reverts when he dies. That arrangement is why the peninsula has no independent religious foundations, no private property and no way for a new group to establish itself outside the existing structure.

7. How the Holy Mountain Came to Be

Mount Athos became monastic gradually, with hermits arriving on the peninsula well before any organised community existed there. Documentary evidence of monks on Athos runs back to the ninth century, when imperial acts already treat the mountain as a place of ascetics whose way of life should be protected from shepherds and settlers.

The founding of Great Lavra and the first Charter

Organised monasticism dates from 963, when Athanasios the Athonite founded Great Lavra with the backing of his friend the Emperor Nikephoros II Phokas. A large cenobitic house on a mountain full of solitaries was controversial among the existing hermits, and the quarrel was settled by imperial intervention. In 972 the Emperor John I Tzimiskes issued the first typikon of the Holy Mountain, a document known as the Tragos from the goatskin it is written on, which regulated relations between the hermits and the communities and remains the founding constitutional text of Athos. A second imperial typikon followed in 1045 under Constantine IX Monomachos.

The Latin monastery on Athos

Benedictine monks kept a Latin house on Athos, the Monastery of the Amalfitans, founded in the later tenth century by monks from Amalfi and functioning for roughly three hundred years before it faded and its property passed to Great Lavra. Latin monks therefore signed Athonite documents alongside Greeks and Georgians both before and after the mutual excommunications of 1054, which is a useful corrective to the idea that the split was instantaneous. Our page on the Great Schism of 1054 and what actually happened traces how slowly the separation hardened.

Crusaders, Catalans and Ottomans

The Fourth Crusade and the Latin Empire brought Athos under Western political control in the early thirteenth century, and the houses appealed to Rome for protection of their property. The mercenary Catalan Company raided the peninsula early in the fourteenth century and did serious damage. Ottoman rule came in the first half of the fifteenth century, when the Athonite houses submitted to the sultan, and the monasteries negotiated their survival through taxation and a large measure of internal freedom, with imperial guarantees repeatedly renewed. Athonite houses became a refuge of Greek learning under Ottoman rule and paid heavily for it in confiscated estates.

The Philokalia and the Kollyvades

The eighteenth century produced the Athonite book that travelled furthest beyond the peninsula. Saint Nikodemos the Hagiorite and Saint Makarios of Corinth compiled the Philokalia, an anthology of ascetic and mystical texts on inner prayer drawn from across the Greek Fathers, and it was printed in Venice in 1782. The compilers belonged to a movement of Athonite traditionalists, the Kollyvades, who argued for frequent communion and for the strict observance of liturgical custom, and who were fiercely opposed on the Mountain in their own day. Translated into Slavonic and then Russian, the Philokalia shaped Russian spirituality for the following two centuries.

Into the modern state

Greek forces took the peninsula during the Balkan Wars in 1912, and its international status was debated afterward. The Athonite community drew up its own Constitutional Charter in 1924, Greece ratified it in 1926, and Article 105 of the present Greek Constitution, adopted in 1975, restates the arrangement. When Greece joined the European Communities in 1979, a joint declaration annexed to the accession instruments recorded the special status of Mount Athos on spiritual and religious grounds.

8. The Avaton: The Rule That Bars Women

The avaton is the Athonite rule that no woman may set foot on the peninsula, and it applies to the whole territory without exception for rank, nationality or purpose. Athonites treat it as immemorial custom rather than a policy adopted at a date, and the earliest surviving written formulation of it appears in the imperial typikon issued under Constantine IX Monomachos in 1045. The Constitutional Charter of 1924 keeps it in force, and Greek law backs it with penalties for unauthorised entry.

How far the rule reaches

The prohibition covers the land boundary at the isthmus and the coastline, and vessels carrying women are kept at a distance offshore rather than approaching the shore, so that the enclosure holds from the sea as well. Coastal cruises along the Athonite shore operate on that basis, which is why the standard way for a woman to see the monasteries is from a boat holding a set distance off the coast.

The same rule has traditionally excluded female domestic animals from the peninsula, with the practical exceptions everyone acknowledges: cats are kept, and hens have been permitted for eggs used in preparing pigments for icon painting. That detail is worth noticing, because it shows the rule was framed as a removal of every occasion from the monks' environment rather than as a judgement about women.

Enforcement and exceptions

Entry without a permit is an offence under Greek law, and the police detachment on the peninsula enforces it. Documented exceptions have occurred in emergencies, and the case most often cited is the Greek Civil War of the late 1940s, when refugees including women and children sheltered on Athos. Occasional unauthorised landings by individuals have been reported and prosecuted. None of these has changed the rule.

The legal challenges

The avaton has been challenged politically rather than judicially, and it has survived. When Greece acceded to the European Communities in 1979, the accession instruments carried a joint declaration acknowledging that the special status of Mount Athos, guaranteed by Article 105 of the Greek Constitution, is justified on spiritual and religious grounds, which preserved the arrangement against later free movement and equal treatment law. The European Parliament has since debated the rule and adopted non-binding language critical of it, most notably in a report on women's rights in the early 2000s, and no change followed. The Greek state's consistent position has been that the status is constitutionally entrenched and the internal rule belongs to the monastic community.

The constitutional recognition of the Athonite regime is set out in Article 105 of the Constitution of Greece, published by the Hellenic Parliament. The joint declaration on Mount Athos is annexed to the 1979 instruments of Greek accession to the European Communities, published in the Official Journal.

9. The Reasons the Athonites Give

Athonites give three connected reasons for the avaton, and all three are worth hearing in their own terms before anyone weighs them. The reasons concern the dedication of the peninsula, the protection of the monastic vocation, and the nature of enclosure.

The Garden of the Mother of God

Athonite tradition holds that the peninsula belongs to the Mother of God as her own garden, the Perivoli tis Panagias, and that she is the only woman of the place. The tradition attaches to a story of her landing on the Athonite shore, and the monks understand the whole territory as hers by dedication. On that reading the avaton is a consequence of the dedication rather than a restriction added to it, and the monks describe themselves as guests on land that is not theirs either.

The protection of the vocation

The second reason concerns the monks. Celibacy lived at that intensity, in silence, for a whole lifetime, has always been protected by the removal of occasions, and the older Athonite documents extend the same exclusion to beardless youths and to female animals. The rule as the Athonites frame it addresses the monk's own weakness and orders his environment accordingly. A monk who is asked about the avaton will commonly answer that the rule exists because of what he is, and the answer is meant seriously.

Enclosure at the scale of a peninsula

The third reason is structural. Athos functions as the enclosure of a single monastic house that happens to cover fifty kilometres of land, and enclosure in that sense is a familiar institution in Latin monasticism as well. Carthusian and Carmelite houses maintain a papal enclosure that outsiders of the other sex do not enter, and Catholic canon law provides for it in monasteries of contemplative nuns. Athos applies the same principle to a whole territory because the whole territory is the monastery.

The criticism, stated fairly

The case against the avaton is straightforward and deserves the same courtesy. Critics argue that a blanket exclusion by sex is discrimination that no other reason would justify, that it withholds from half the population access to a body of European cultural and religious heritage of the first rank, and that it hardened under social conditions that no longer exist. Some Orthodox critics add that the rule is customary rather than dogmatic and could in principle be changed by the same authority that made it.

The Athonite answer is that the peninsula is a monastic enclosure and not a heritage site with visiting hours, that entry for men is itself restricted and conditional rather than a right, and that a rule protecting the interior conditions of a contemplative life is the sort of thing that is destroyed by being relaxed. The Catholic Church has no jurisdiction over Athos and has never asked for the rule to change. The Catholic reader who finds the exclusion uncomfortable can hold two things at once, that the practice of strict enclosure is honourable and ancient, and that its Athonite scale is unique in Christianity.

10. The Permit System, in Principle

Entry to Mount Athos runs on a written permit called a diamonitirion, issued by the monastic authorities rather than by the Greek state. The permit is applied for in advance, it names one person and a set of dates, it is not transferable, and it is collected at the port before boarding on production of a passport or identity card. The principles behind it have held for a very long time, and the administrative details around it move, so the durable shape is what follows.

The permit is monastic, not civil

Nothing about the diamonitirion resembles a visa or a museum ticket. The document is a written act of hospitality from the Holy Community, addressed to the monasteries, asking them to receive the bearer as a pilgrim. That is why it is signed and sealed by the Epistasia and why it speaks the language of reception rather than of admission.

The daily cap and the two allocations

The number of pilgrims admitted each day is capped, and the cap is divided into a larger allocation for Orthodox pilgrims and a smaller one for non-Orthodox visitors. The distinction is deliberate and long standing: Athos exists as a place of Orthodox monastic prayer, and the community keeps the majority of its limited hospitality for people who come to share in it sacramentally. Because the non-Orthodox allocation is small, Catholic and other non-Orthodox pilgrims usually have to apply a long way ahead.

Length of stay

The permit runs for a fixed and short number of nights. Extension is possible by application to the Holy Community at Karyes, granted at its discretion, and monks and clergy travelling on monastic business are handled separately. Anyone hoping to stay longer should assume the short period is the norm and treat an extension as a favour.

A permit is not a bed

The diamonitirion admits you to the peninsula, and each monastery decides separately whether it has room for you on a given night. Beds are arranged with the individual houses in advance, through their guest offices, and the guest master of a house may turn a pilgrim away when the guest quarters are full or the house is keeping a feast. Arriving without a bed arranged is unwise, since the gates close at sunset and there is no alternative accommodation anywhere on the peninsula.

Clergy and religious

Orthodox clergy from jurisdictions outside the Ecumenical Patriarchate require the Patriarchate's permission in addition to the ordinary permit. Non-Orthodox clergy are received, when they are received, as ordinary lay pilgrims rather than in any clerical capacity, and a Catholic priest visiting Athos should expect to be treated as a layman and should not wear clerical dress or expect to concelebrate anything.

11. Who Is Admitted and Who Is Not

Mount Athos admits adult men, of any nationality and of any Christian confession or none, on a capped daily quota and by advance permit. Women are not admitted at all. Those two sentences cover the great majority of questions people ask about access.

Orthodox and non-Orthodox pilgrims

Orthodox pilgrims form the larger allocation and are received into the full life of the house: they attend the services, they may receive Holy Communion where the monastery permits it and their own preparation allows it, and they take their meals with the community in the refectory. Non-Orthodox visitors are received as guests. They may attend the services, they commonly stand in the narthex or the outer part of the church rather than in the nave, and they do not receive Holy Communion. Some houses receive non-Orthodox guests readily and some are markedly more reserved, and a few restrict which parts of the monastery non-Orthodox guests may enter.

Minors

Boys under age are admitted only in the company of their father or another adult answerable for them, and the practice descends directly from the old prohibition on beardless youths in the imperial typika. Groups of teenagers do not go to Athos.

Workers and others

Lay workmen employed by the monasteries, drivers, boatmen, foresters, builders and conservators live and work on the peninsula under separate arrangements with the houses that employ them. They are all male, under the same rule, and their presence does not change the character of the place.

What a non-Orthodox visitor should expect

A Catholic or Protestant pilgrim on Athos is a guest inside another church's monastery during its own liturgy. Expect to be shown where to stand, to stand for a long time, to be given food and a bed as the house's hospitality, to be asked no questions and to be offered no argument. The reserve some houses show toward non-Orthodox guests follows from a settled conviction about the communion of the Church rather than from any personal coldness, and taking it personally is a mistake. Our guide to what the Eastern Orthodox Church believes and how it is governed sets out that conviction in Orthodox terms.

12. The Athonite Day, the Clock and the Calendar

The Athonite day begins in the middle of the night and is measured by two systems that both differ from the ones used in the rest of Greece. Mount Athos keeps the Julian calendar for its fixed feasts, currently thirteen days behind the civil calendar, and most of its houses keep Byzantine time, in which the day starts at sunset and the clocks are reset to twelve as the sun goes down.

Byzantine time

Setting the clock to twelve at sunset means the hours slide through the year with the length of the day, so a service that begins at three in the Athonite reckoning falls at a different civil hour in December and in July. The whole horarium follows the sun. Visitors are told the times of services in Athonite hours and are best served by asking the guest master what that means on the day. Iviron is usually described as the exception among the twenty, reckoning its hours from sunrise rather than sunset.

The Julian calendar

Athonite houses observe the old calendar throughout, so the fixed feasts fall thirteen days later than they do on the civil calendar. Pascha is calculated by the Orthodox reckoning, which is why it usually falls on a different Sunday from the Western date. The calendar is one of the reasons Athos feels dislocated from ordinary Greek life even though it sits inside it.

The shape of a day

A wooden board called a semantron is struck to call the community, and the night office begins in the small hours. Midnight office, matins and the hours run into the Divine Liturgy, and the community goes from the church straight into the refectory, where the meal is eaten in silence while a monk reads aloud from a stand. Work follows, the diakonima, each monk in his assigned obedience: the garden, the kitchen, the forest, the guest house, the library, the icon workshop. Vespers comes in the late afternoon, the second meal follows on days when there is one, compline closes the day, and the gates are shut at sunset.

On the great feasts the pattern is replaced by an agrypnia, an all-night vigil that runs for many hours without a break, from evening into the following morning. Pilgrims who arrive on a vigil day should understand what they are joining and should plan to sleep afterward rather than before.

Food and fasting

Meat is never served on Mount Athos. The Athonite table is fish, pulses, vegetables, bread, olives, cheese and wine, and it contracts sharply during the fasting seasons, when oil and wine are restricted and the community eats once a day. Guests eat what the community eats. The refectory follows immediately on the liturgy and the meal is treated as an extension of it, which is why latecomers are not fed and why nobody talks.

Hospitality

Arriving pilgrims are received at the guest house, the archontariki, by the guest master, and the traditional welcome is a piece of loukoumi, a small glass of tsipouro or raki, a coffee and a glass of cold water. Athonite houses have not traditionally charged pilgrims for a bed or for meals, and the hospitality is given as an act of the monastic vocation. An offering left for the church is the usual courtesy in return.

13. Hesychasm and the Jesus Prayer

Hesychasm is the Athonite tradition of inner stillness, and it is the reason the Holy Mountain matters to Orthodox theology out of all proportion to its size. The word comes from the Greek hesychia, meaning stillness or quiet, and it names a discipline of interior prayer in which the mind is gathered into the heart through the constant repetition of a short invocation of Christ.

The prayer itself

The Jesus Prayer in its common Athonite form runs: Lord Jesus Christ, Son of God, have mercy on me, a sinner. Monks pray it thousands of times through the day, counted on a knotted wool rope called a komboskini, until the words continue under work, walking and sleep. The practice takes its scriptural grounding from Saint Paul's instruction to pray without ceasing (1 Thessalonians 5:17), from the tax collector's prayer in the temple (Luke 18:13), and from the blind man's cry outside Jericho (Mark 10:47).

The hesychast controversy

In the fourteenth century the Athonite practice was attacked by Barlaam of Calabria, a learned Greek from southern Italy, who ridiculed the physical methods some monks used and argued that the light the hesychasts claimed to experience could not be God himself, since God in his essence is unknowable. Saint Gregory Palamas, a monk of Athos who later became Archbishop of Thessaloniki, answered him with a distinction between God's essence, which remains forever beyond every creature, and God's uncreated energies, in which God genuinely gives himself and can be known and participated. The monks of the Holy Mountain endorsed Palamas in a document known as the Hagioritic Tome around 1340, and councils held at Constantinople in 1341, 1347 and 1351 upheld his position, which the Orthodox churches have held as their own ever since.

Where Catholics stand on it

The Catholic Church has never condemned hesychasm, and Catholic theologians have taken a range of positions on the essence and energies distinction, some finding it compatible with the Western understanding of grace and the beatific vision, others regarding it as a genuine difference in the doctrine of God that ecumenical discussion has yet to resolve. The prayer itself is Catholic property as much as Orthodox. The Catechism of the Catholic Church treats the invocation of the holy name of Jesus and gives its most usual form as "Lord Jesus Christ, Son of God, have mercy on us sinners", a formulation it says was transmitted by the spiritual writers of Sinai, Syria and Mount Athos (CCC 2667). A Catholic can pray the Jesus Prayer today without borrowing anything that is not already his.

Athos gave that prayer its literature. The Philokalia, compiled on the Holy Mountain in the eighteenth century, is the standard anthology of hesychast teaching, and it is the reason the tradition spread from a Greek peninsula to Russian villages and then to the whole Christian world. Readers wanting the wider Catholic teaching on interior prayer can begin with our guide to what prayer is and how the Church teaches it.

14. Libraries, Relics and Icons

Mount Athos holds one of the largest surviving concentrations of Byzantine manuscripts, documents, icons and liturgical metalwork anywhere, kept in the treasuries and libraries of the twenty houses. The collections survived because Athos was never sacked in the way Constantinople was and because monastic archives kept property documents for a thousand years as a matter of legal necessity.

The Protaton at Karyes

The oldest church on the peninsula stands at Karyes: the Protaton, the church of the whole community rather than of any single monastery. Its wall paintings are a major surviving monument of Palaiologan painting and tradition attributes them to Manuel Panselinos, an artist about whom almost nothing certain is known and whose name has come to stand for the Macedonian school of Byzantine painting.

Icons the houses venerate

Several icons on Athos carry their own long traditions and their own feasts. The Protaton keeps the icon called Axion Estin, associated with a hymn to the Mother of God that Athonite tradition says was taught to a monk at a cell nearby. Iviron keeps the Portaitissa, the Gatekeeper, whose story of arrival by sea is told at the monastery. Vatopedi venerates the Holy Girdle of the Mother of God and a series of miraculous icons of its own. Each of these is a tradition held and told by the house that keeps it, and Athonites present them as such rather than as anything a historian could verify.

Books and archives

The libraries hold Greek, Slavonic and Georgian manuscripts, imperial chrysobulls and Ottoman firmans, and the archives of the twenty houses together form a continuous documentary record of the peninsula from the tenth century onward. Cataloguing and conservation programmes have run for decades in cooperation with academic institutions, and digitised material has made a body of texts available to scholars who will never be admitted to the peninsula in person.

The scale and significance of the Athonite artistic and documentary holdings are described in the World Heritage listing published by the UNESCO World Heritage Centre.

15. Eastern Orthodox, Not Oriental Orthodox

Mount Athos is Eastern Orthodox in full, in communion with the Ecumenical Patriarchate of Constantinople and with the other Eastern Orthodox churches. The Oriental Orthodox churches are a separate communion, and no Oriental Orthodox monastery exists on the Holy Mountain.

The Eastern Orthodox communion includes the ancient patriarchates of Constantinople, Alexandria, Antioch and Jerusalem, the Russian, Serbian, Romanian, Bulgarian and Georgian churches, the Church of Greece and others. The Oriental Orthodox communion is made up of the Coptic Orthodox Church, the Armenian Apostolic Church, the Ethiopian and Eritrean Orthodox Tewahedo Churches, the Syriac Orthodox Church and the Malankara Orthodox Syrian Church. The two families divided over the Council of Chalcedon in 451 and its formula about the two natures of Christ, and they remain out of communion with one another, though modern dialogues have produced substantial agreed statements on Christology.

The distinction matters on a page about Athos because the Athonite houses that carry national names, Serbian Hilandar, Bulgarian Zographou, Russian Saint Panteleimon, Georgian founded Iviron, are all Eastern Orthodox houses of one communion. Athos has never held a Coptic, Armenian, Ethiopian or Syriac monastery. Our guides to the Oriental Orthodox churches and what distinguishes them and to the Greek Orthodox Church and its structure keep the two families straight.

16. A Catholic Reader and the Holy Mountain

A Catholic approaching Mount Athos is approaching a monastic republic of another church, and the Catholic Church's own teaching is clear about what that means. The Catholic Church recognises in the Eastern churches true sacraments, apostolic succession and a monastic tradition from which the whole Church has drawn, and it recognises equally that full communion between Rome and the Orthodox churches does not currently exist.

What the Catholic Church says

The Second Vatican Council's decree on ecumenism praises the Eastern churches by name for their liturgical and spiritual inheritance and singles out Eastern monasticism as a treasure of the whole Church (Unitatis Redintegratio 15). The Catechism teaches that communion with the Orthodox churches is so profound that it lacks little to attain the fullness that would permit a common celebration of the Eucharist (CCC 838), and that those churches, though separated from Rome, possess true sacraments and above all, through apostolic succession, the priesthood and the Eucharist (CCC 1399). The same teaching holds that the separation is real and that intercommunion is not open on either side while it lasts.

What that means in practice on the peninsula

A Catholic guest on Athos does not receive Holy Communion, and should not ask. The Orthodox discipline does not admit Catholics to communion, and the Catholic Church asks its own faithful to respect the discipline of the Eastern churches in their own houses. The right posture is that of a guest: stand where you are put, keep silence, venerate an icon if you are invited to and stand back if you are not, and let the house set the terms.

The Athonite view of Rome, stated in its own terms

Athonite opinion about the Catholic Church runs from courteous distance to open opposition, and the opposition is theological. Athonite writers hold that the papal claims defined at the First Vatican Council and the insertion of the Filioque into the Creed are departures from the faith of the undivided Church, that the doctrinal questions must be settled before any gesture of unity, and that the ecumenical meetings of recent decades have obscured rather than clarified the difference. Several houses have petitioned the Ecumenical Patriarchate on the point. Anyone reading Catholic accounts of dialogue with Orthodoxy should hold that alongside them, and our page on Catholic ecumenism and what unity would actually require sets out the Catholic side without pretending the gap is smaller than it is.

The Amalfitan precedent

The Latin monastery on Athos, the house of the Amalfitans, lasted roughly three centuries and is a fact worth remembering on both sides. Benedictines kept the Latin office on the Holy Mountain, held a place among the ruling houses, and signed the community's acts alongside the Greeks. Whatever the present distance, the Holy Mountain has held Latin monks within its own constitution before.

If you cannot go

Most readers of this page will never receive an Athonite permit, and the women reading it never will at all. The Athonite tradition, though, has always insisted that the interior work is portable and that a cell is wherever a person keeps silence and prays. Our guides to making a pilgrimage without leaving home and to visiting Orthodox monasteries as a pilgrim take that further, and what a pilgrimage actually is in Catholic practice gives the framework.

17. Dress, Silence and Conduct

Athonite conduct rules are the ordinary rules of a monastic enclosure applied to an entire peninsula, and they are enforced by custom rather than by signage. A visitor who behaves as he would in the choir of a working monastery will not put a foot wrong.

Dress

Long trousers and sleeved shirts are expected everywhere on the peninsula, indoors and out. Shorts are not worn on Athos at any time, shirts stay on in the heat, and swimming is not done. Hats come off in church. The standard applies on the paths between houses as much as inside them, because the whole territory is the monastery.

Silence

Silence is kept in the church, in the refectory during meals, and through the night after compline until the semantron sounds. Conversation in the guest house during the day is normal and monks are often glad of it. The rule to carry is that silence is the default and speech is the exception, which inverts ordinary habits and takes a day to learn.

Photography and recording

Photography of monks without their permission is not acceptable, and filming and audio recording inside churches, and of services anywhere, are restricted or forbidden. Assume that recording is not permitted until a monk tells you otherwise, and put the phone away during services. Drone use is prohibited.

In church

Services are long and standing is the norm, with wooden stalls along the walls whose arm rests are designed to take some weight. Non-Orthodox guests usually stand in the narthex. Do not walk about during a service, do not cross in front of the royal doors, do not join the communion procession, and follow the movements of the guests around you rather than improvising. Venerating an icon by a kiss is the ordinary Orthodox gesture, and a non-Orthodox guest who prefers a bow is not causing offence.

Practical courtesies

Arrive before sunset, because the gates close and the peninsula has nowhere else to sleep. Tell the guest master your plans and stick to them, since the next house is expecting you. Smoking is restricted or forbidden in most houses and is never done in the courtyards during services. Walk the paths with water and daylight to spare, since the distances are longer than they look on a map and the terrain is steep.

The frame around all of it

Athonite hospitality is generous, and it is given by men who have arranged their entire lives around a schedule that a visitor interrupts. The courtesy that matters most is to fit the house rather than asking the house to fit you.
