The Greek Orthodox Church: A Visitor's Guide to Faith, Icons and Etiquette

Most visitors to Greece walk into an Orthodox church within a day of landing, usually without meaning to. Kapnikarea sits in the middle of Athens' main shopping street, every island village has a whitewashed chapel, and the monasteries of Meteora are among the most visited sights in the country. What surprises people is that none of this is a museum. About nine in ten Greeks identify as Orthodox Christians, the constitution names Orthodoxy the prevailing religion, and the church you wander into on a quiet afternoon may be full on Sunday morning.

Once you know what to look for, that living tradition is everywhere: the screen of icons that hides the altar, Christ Pantokrator looking down from the dome, silver tamata hanging beside a favoured icon, trays of thin beeswax candles by the door and the smell of incense that stays in your clothes. The same Church sets the Greek calendar, which is why Easter moves every year, Christmas stays on December 25 and tavernas put fasting dishes on the menu in the first two weeks of August.

This guide explains what the Greek Orthodox Church is and how it differs from Catholicism, what you are looking at inside a Byzantine church, where to see the best of it, and how to dress and behave so you are welcome in any church or monastery in Greece.

What Is the Greek Orthodox Church?

The Greek Orthodox Church is part of Eastern Orthodox Christianity — the branch of Christianity that developed in the Byzantine Empire (Eastern Roman Empire) after the formal split with Western (Roman Catholic) Christianity in 1054 AD.

For how the Byzantine centuries fit between Roman Greece and the Ottoman period, our Greek history timeline sets out every period in order.

The Great Schism: The separation of 1054 was theological, political, and cultural. Eastern and Western Christianity had already been diverging for centuries in language (Greek vs Latin), governance (Patriarch of Constantinople vs Pope of Rome), and practice. The formal break — the Schism — was the culmination of these differences rather than a single rupture. The result was two distinct Christian traditions that developed in isolation from each other for nearly a millennium.

Greek Orthodox vs Catholic: The Key Differences

• Authority: No pope. The Orthodox Church is a communion of autocephalous (self-governing) national churches — the Greek Church, the Russian Church, the Serbian Church, and others — each led by its own patriarch. The Ecumenical Patriarch of Constantinople is a first among equals, not a supreme authority.
• Theology: Different emphasis on the nature of the Holy Trinity, the role of icons, and the understanding of theosis (the idea that human beings can participate in divine nature).
• Visual tradition: Byzantine art — gold mosaics, flat icons, specific pictorial conventions — rather than the naturalistic religious art of the Western Renaissance.
• Liturgical calendar: Easter is calculated on the old Julian calendar, so it falls on the same day as Western Easter only in some years and otherwise one, four or five weeks later. The Church of Greece has kept its fixed feasts on the revised calendar since 1924, so Christmas in Greece is on December 25, not January 7.
• Priests and communion: married men can be ordained priests, though a priest cannot marry after ordination and bishops are chosen only from celibate monks. Communion is given with leavened bread and wine together, from a spoon.
• Language: the liturgy in Greece is sung in the Koine Greek of the New Testament rather than modern Greek, so many Greeks follow parts of it by heart rather than word by word.

Greek Orthodox vs Russian Orthodox

They are the same faith. The Greek, Russian, Serbian, Romanian and other Orthodox churches share one creed, the same sacraments and the same liturgy; what differs is the language of worship, the national church that runs them and some customs.

The Russian Church still keeps its fixed feasts on the old Julian calendar, which is why Russians celebrate Christmas on January 7 and Greeks on December 25. Russian churches lean toward onion domes and the three-bar cross, Greek ones toward low round domes and the equal-armed cross. Relations between Moscow and the Greek-speaking churches have been strained since 2018 over the status of the Church in Ukraine.

The Church in Greece Today

About 90 percent of Greeks identify as Orthodox Christians, according to Pew Research Center, one of the highest shares in Europe, and 55 percent say religion is very important in their lives. Article 3 of the Greek constitution names Eastern Orthodoxy the prevailing religion, there is no formal separation of church and state, and the salaries of Orthodox priests are paid by the state. Priests bless the start of every school year, and new governments are usually sworn in by the Archbishop of Athens.

Administratively, Greece is not one church. The Church of Greece, led by the Archbishop of Athens, covers most of the mainland and islands. Crete has its own semi-autonomous Church of Crete. The Dodecanese, including Rhodes and Patmos, answer directly to the Ecumenical Patriarchate in Istanbul, as does Mount Athos, and much of northern Greece belongs to the Patriarchate on paper but has been run by the Church of Greece since 1928. A small minority of Old Calendarists, who call themselves Genuine Orthodox Christians, rejected the 1924 calendar change and still celebrate Christmas on January 7.

Priests, Monks and Bishops

The village priest, the papas, is usually a married man with a family, recognisable by his black cassock, long beard and tall black hat, the kalimafki. Greeks greet a priest with evlogeite, bless me, and older people kiss his hand. Bishops, by contrast, are chosen only from monks, who take vows of celibacy, so every senior figure in the Church has a monastic background.

Monks and nuns live in monasteries across Greece, from the six active ones at Meteora to the twenty ruling monasteries of Mount Athos, and most still welcome respectfully dressed visitors at set hours.

The Greek Orthodox Cross and Other Symbols

The cross you see on Greek churches and around Greek necklaces is usually the Greek cross, with four arms of equal length, or a plain Latin-proportioned cross without a figure. The three-bar cross with a slanted lower bar belongs to the Russian and Slavic tradition and is rarely seen in Greek churches. On icons, and on the stamp pressed into communion bread, you will see the letters IC XC NIKA around a cross: the first and last letters of Jesus Christ in Greek, and nika, conquers.

The yellow flag with a black double-headed eagle that flies beside the Greek flag outside many churches is the flag of the Church, inherited from the Byzantine Empire; its two heads are usually read as East and West. The letters ΦΧΦΠ over church doors and on Easter candles stand for Fos Christou fainei pasi, the light of Christ shines on all.

Byzantine Church Architecture: What You Are Looking At

The term Byzantine church describes the architectural tradition that developed in the Eastern Roman Empire from the fourth century onward and continued in Greece through the medieval and Ottoman periods. Understanding the architectural vocabulary helps enormously when visiting.

The Plan

Byzantine churches typically follow a Greek cross plan — a nave (the main space) intersecting with arms of equal or near-equal length, topped by a central dome. This differs from the Latin cross plan of Western Gothic cathedrals, where the nave is much longer than the transept. The Greek cross creates a more compact, vertically oriented space in which the dome becomes the dominant focus.

The dome: In Orthodox theology, the dome represents the vault of heaven. The image painted or mosaicked inside the dome is almost always the Pantokrator — Christ as ruler of all things, depicted in bust, with a specific hand gesture and book. He looks directly down at the congregation.

The Iconostasis

The defining feature of an Orthodox church interior and the most important thing to understand. The iconostasis (εικονοστάσιο) is a screen — ranging from a simple row of icons in small chapels to a towering gilded structure with multiple tiers in larger churches — that separates the nave (where the congregation stands) from the sanctuary (the altar space, where the clergy officiate).

The iconostasis has three doors:

• The Royal Doors (central): Used only by the clergy, opened during key moments of the liturgy. What is visible through the open Royal Doors is the altar and the liturgical action.
• The North and South Doors: Used by deacons and other servers.

The images on the iconostasis follow a fixed pattern: the Pantokrator, the Virgin (Theotokos), specific saints in specific positions, with the icons of the church's patron saint prominently placed.

The theological meaning: The iconostasis is not a wall to keep the congregation away from the altar. It is a representation of the boundary between the earthly and divine realms — a screen of sacred images through which the mystery of the Eucharist is partly visible and partly hidden. The Royal Doors open to reveal the divine action; they close to conceal it.

Icons: Theology in Image

Orthodox icons are not religious paintings in the Western sense. They are theological statements made in visual form, painted according to rules that have been continuous since the Byzantine period.

Reversed perspective: Western painting uses linear perspective to create an illusion of depth — objects recede to a vanishing point. Orthodox icons use reversed perspective: lines converge toward the viewer rather than away. This is not artistic incompetence. It is a theological statement: the icon space is coming toward the viewer, not receding from them. The saint inhabits the viewer's space, not a represented space.

Gold backgrounds: The gold background of icons represents divine light — the uncreated light of God rather than natural illumination. The figures exist in eternity, not in time or space.

Specific attributes: Each saint can be identified by specific visual attributes that are consistent across centuries and across different icon painters. Saint Nicholas: bishop's vestments, specific hand gesture. Saint George: on horseback, killing a dragon. The Theotokos (Virgin): specific positions (Orans — arms raised; Hodegetria — pointing to the Christ child; Eleousa — cheek to cheek with the child). These are not stylistic choices but codified theology.

Venerating icons: In an active Orthodox church, you will see people approach icons, kiss them, and make the sign of the cross. This is not idol worship — a distinction the Orthodox tradition takes very seriously. The veneration is directed toward the person represented, not the object itself.

Key Byzantine Sites in Greece

This is the short version: the places that best show what Orthodox Greece looks like. For a full tour of the Byzantine monuments, period by period, see our guide to Byzantine Greece.

Thessaloniki

Greece's second city is the single most important location for Byzantine architecture and mosaic art in the country. The city has fifteen early Christian and Byzantine monuments designated as UNESCO World Heritage Sites.

Hagios Demetrios: One of the largest basilicas in Greece, dedicated to Thessaloniki's patron saint. The original was built in the fourth century. Despite destruction and rebuilding, it retains early Byzantine mosaics and an atmosphere that is genuinely ancient.

Rotunda: Originally built as a mausoleum for the Emperor Galerius in 306 AD, converted to a church, later to a mosque, now a museum. Its fourth-century mosaics are among the finest surviving examples of early Byzantine art.

Hagios Georgios, Hagios Sophia, the Acheiropoietos basilica: A circuit of Byzantine churches spanning eight centuries of continuous development, all within walking distance of the city centre.

For the rest of the city, see our Thessaloniki travel guide.

Meteora

The monasteries of Meteora, perched on extraordinary sandstone pillars in the Thessalian plain, are the most dramatically sited Orthodox monasteries in the world. Originally established in the fourteenth century, they were built on rock formations accessible only by rope ladders. Six are still active. The frescoes inside contain some of the finest examples of post-Byzantine painting.

Plan around two rules. Women need a skirt below the knee, with loan wraps at each entrance, and men need long trousers. And each monastery closes on one or two days a week, a different day for each, so check before you drive up. Our Meteora travel guide covers which monasteries to prioritise, the old monk paths between them and where to stay in Kalambaka.

Mount Athos (Holy Mountain)

The Athos peninsula in northern Greece contains twenty ruling monasteries and is one of the most important sites in all of Orthodox Christianity — a semi-autonomous monastic state that has existed continuously since the tenth century. Women are not permitted to enter; men require a special permit (diamonitirion) issued in limited numbers. For those who can access it, the experience of active monastic life in Byzantine-era buildings is extraordinary.

Athens Byzantine Churches

The most accessible Byzantine church in Athens is the Kapnikarea in the Ermou shopping street — a small eleventh-century church sitting incongruously in the middle of a pedestrianised commercial street. Despite its modest size, it is an intact example of middle Byzantine architecture and significantly older than almost anything else visible in central Athens.

A few minutes' walk away, the Metropolitan Cathedral (Mitropoli), finished in 1862, is the seat of the Archbishop of Athens and the church of state funerals and the big Easter services. Beside it sits the far older Little Metropolis (Panagia Gorgoepikoos), a tiny church from around the twelfth century built almost entirely from reused ancient and Byzantine marble reliefs. Inside the Ancient Agora, the Church of the Holy Apostles, from around the year 1000, is covered by the Agora ticket, and on the summit of Lycabettus the whitewashed chapel of Agios Georgios has the best view of any church in the city. Our guide to things to do in Athens fits them into a day.

The Byzantine and Christian Museum in Athens holds one of the most important collections of Byzantine art in the world — icons, mosaics, sculptures, and decorative objects from the fourth to the twentieth century.

Beyond the Big Names: Mystras, Hosios Loukas, Patmos and the Island Monasteries

Three more places belong on any Orthodox itinerary, all of them UNESCO World Heritage Sites. Mystras, above Sparta, is a whole ruined Byzantine city of churches and palaces on a hillside, with a convent still working inside it. Hosios Loukas, near Delphi, and Daphni, on the western edge of Athens, are two of the three eleventh-century monasteries UNESCO lists together for their gold mosaics; the third, Nea Moni, is on Chios. On Patmos, the fortified Monastery of Saint John the Theologian and the Cave of the Apocalypse below it have drawn pilgrims for more than nine hundred years.

The islands add their own. The Panagia Evangelistria on Tinos is the most important Marian pilgrimage church in Greece. The Monastery of Panagia Chozoviotissa on Amorgos is built into a sheer cliff above the sea and dates from the eleventh century. And the Monastery of the Archangel Michael at Panormitis on Symi is a place pilgrims still reach by boat.

Visiting an Orthodox Church: What to Know

Dress

Modest dress is required at all Orthodox churches, monasteries, and pilgrimage sites. Practically:

• Women: Covered shoulders; skirts or trousers below the knee. Scarves and wraps are often available at the entrance of major sites.
• Men: Covered shoulders; trousers rather than shorts at more traditional monasteries (this varies by site).
• Closed shoes are generally expected at monasteries.
• Hats off inside, and nothing see-through or beachwear for anyone. At Meteora, trousers are not enough for women; the full rules, including what gets men turned away, are in our guide to what to wear in Greece.

Opening Hours, Entry Fees and Photography

Parish churches are free and usually open in the morning and again in the late afternoon, often locked in the middle of the day; many small chapels open only on their saint's feast day. Byzantine churches inside archaeological sites, such as the Holy Apostles in the Ancient Agora or Daphni, need a ticket, and each Meteora monastery charges a small entrance fee. Monasteries keep shorter hours than parish churches and often close by late afternoon.

Photography is generally fine in an empty church, but never with flash, which damages old pigment, never of the sanctuary behind the icon screen, and never during a service. Many monasteries ban photography inside altogether and say so with a sign at the door.

Behaviour During Services

The main service is the Divine Liturgy on Sunday morning, preceded by Orthros (matins), so a typical parish church is busy from around 7am to 10:30am; there are also services on major feast days and every evening of Holy Week. If you enter a church during an active service:

• Stand quietly. Orthodox services are standing services — there are sometimes benches along the walls for the elderly, but the congregation generally stands.
• Do not photograph during an active service.
• Light a candle if you wish — there are usually trays of candles near the entrance; a small donation is customary.
• You may observe the liturgy from anywhere in the nave. Do not cross into the sanctuary (the area behind the iconostasis).
• If you sit, do not cross your legs; keep your hands out of your pockets, and try not to turn your back on the altar when you leave.

If you are not Orthodox, do not go up for communion: the Orthodox Church gives it only to baptised Orthodox Christians, and that includes Catholics and Protestants. At the end of the liturgy, though, the priest hands out antidoron, pieces of blessed bread, and anyone may take one. Hold your hands cupped, right over left, and say efharisto.

Candles

Lighting a candle in an Orthodox church is a simple devotional act open to anyone. The tray of thin beeswax tapers near the entrance is for this purpose. You place one or a few in the sand tray, light them from those already burning, and offer a silent intention or prayer. A small offering in the nearby box is customary. Non-Orthodox visitors may participate fully in this gesture.

Incense, Chant and Tamata: What You Will Smell, Hear and See

The smell that greets you in any Greek church is incense, swung in a censer during services to honour the icons and the congregation and to stand for prayer rising to heaven. The sound is Byzantine chant. The liturgy is sung without accompaniment by a cantor, the psaltis, at a lectern beside the icon screen, because the Orthodox Church uses no organ or other instruments.

Look closely at a favoured icon and you will see small metal plaques hanging beside it, embossed with an eye, a leg, a heart, a baby or a ship. These are tamata, votive offerings left by people asking for, or giving thanks for, a healing, a safe birth or a safe voyage; the icon of the Panagia Evangelistria on Tinos is hung with them. You may also see a tray of koliva, boiled wheat with sugar, nuts and pomegranate seeds, blessed at memorial services for the dead and shared out afterwards. The Church even has its own prayer against the evil eye, separate from the folk ritual Greek grandmothers use; our guide to the Greek evil eye explains both.

The Sign of the Cross

Orthodox Christians cross themselves from right to left, the opposite of Catholics, with the thumb, index and middle finger held together for the Trinity and the other two fingers folded into the palm for the two natures of Christ. Greeks do it on entering a church, when passing one in the street or on a bus, and before a long journey. If you are not Orthodox, no one expects you to make the sign of the cross; observing respectfully is entirely appropriate.

The Orthodox Calendar and Greek Life

The Orthodox church year begins on September 1. These are the feasts you are most likely to run into as a visitor, several of them public holidays:

The biggest Dormition pilgrimage in Greece is on Tinos, at the Panagia Evangelistria; our guide to things to do in Tinos explains how to visit the church and when to avoid the crowds.

Each of these dates has associated customs, church services, and in many cases public celebrations or nameday gatherings across Greece. The calendar in its entirety shapes the Greek year more than any other single institution.

For the name day side of the calendar, which saint's day belongs to which name, see our guide to Greek name days.

Every church also has its own feast day, the saint it is named after, and in villages and on islands that day is celebrated with a panigiri: a liturgy in the morning, then food, wine and dancing in the square late into the night. Our guide to the Greek panigiri lists the best of them.

Why Christmas Stays Put but Easter Moves

In 1924 the Church of Greece moved its fixed feasts to the revised Julian calendar, which for now matches the Western one, so Christmas, Epiphany and August 15 fall on the same dates as in the rest of Europe. Easter, and everything counted from it, from Clean Monday to Pentecost, is still calculated on the old Julian calendar shared by all Orthodox churches. That is why Greek Easter coincides with Western Easter only in some years and otherwise falls one, four or five weeks later. Mount Athos and the Old Calendarists keep the whole year on the Julian calendar, thirteen days behind. For Holy Week day by day, see our Greek Easter guide.

Fasting: Why Tavernas Advertise Nistisima

Devout Orthodox Christians fast often, which in practice means no meat, dairy or eggs and, on the strictest days, no fish, olive oil or wine either. The main fasts are the 48 days of Great Lent before Easter, the Dormition fast from August 1 to 14, the Nativity fast from November 15 to December 24 and the Apostles' fast before June 29, plus most Wednesdays and Fridays through the year. Far fewer Greeks keep the full rules today, but many still fast in Holy Week, and bakeries and tavernas respond with nistisima, fasting dishes. That is good news if you eat plant-based: our guide to vegetarian food in Greece explains how to ask for them.
