Die Sieben Ökumenischen Konzile – Glaubensdefinitionen auf türkischem Boden
Sechs der Sieben Ökumenischen Konzile fanden auf dem Boden der heutigen Türkei statt.

Beste Reisezeit
April-June and September-October are optimal. Iznik in November 2025 hosted the 1700th anniversary of the First Council (Pope Leo XIV and Ecumenical Patriarch Bartholomew I); commemorative events continue throughout 2026. The Sunday of Orthodoxy (first Sunday of Great Lent — 22 February 2026) is the principal Orthodox liturgical commemoration of the Seventh Council (787, restoration of icons) and is celebrated with particular solemnity at the Ecumenical Patriarchate in Istanbul. The 8 December Catholic feast of the Immaculate Conception relates conciliar to Marian theology.

Stationen dieser Route
Iznik / Nicaea
First Council of Nicaea (325 AD) and Pope Leo XIV's 1700th anniversary visit
Iznik - ancient Nicaea - is the city where the First Ecumenical Council was convened by Constantine in 325 AD, with 318 bishops, condemning Arianism, drafting the original Nicene Creed and fixing the date of Easter. The Seventh Council (787 AD), also at Nicaea, restored the veneration of icons after Iconoclasm.
Istanbul / Constantinople
Capital of Christianity 330-1453 and seat of the Ecumenical Patriarchate
Constantinople was the capital of the Christian world from Constantine's dedication in 330 AD to the Ottoman conquest of 1453 - the longest continuous Christian capital city in history. Here the Second Ecumenical Council (381 AD) at Hagia Irene finalised the Nicene Creed; here the Great Schism of 1054 split Eastern Orthodox and Roman Catholic Christianity (nullified mutually by Pope Paul VI and Ecumenical Patriarch Athenagoras I on 7 December 1965).
Ephesus
House of the Virgin Mary, Basilica of St John and the First Church of Revelation
Paul lived and preached at Ephesus from 53-56 AD (Acts 18-20), wrote Ephesians from prison, and the city is Church number one of the Seven Churches (Revelation 2:1-7). The Apostle John brought Mary here according to a tradition rooted in John 19:26-27.
Cappadocia
Rock-hewn churches of the Cappadocian Fathers
Cappadocia, named in Acts 2:9 and 1 Peter 1:1, became one of the most important monastic landscapes of late antiquity. In the 4th century the three Cappadocian Fathers - Saint Basil the Great of Caesarea, Saint Gregory of Nazianzus and Saint Gregory of Nyssa - decisively shaped Trinitarian theology against Arianism and laid the foundations for Eastern Orthodox monastic life.
Ravenna
World's greatest concentration of Early Christian mosaics
Ravenna was the capital of the Western Roman Empire from 402 AD, then of the Ostrogothic Kingdom of Theodoric, and finally of the Byzantine Exarchate (540-751). The city preserves eight Early Christian monuments - the world's greatest concentration of Early Christian and Early Byzantine mosaics - inscribed by UNESCO in 1996.
