Historical Christian sites
Antioch (Antakya), the city where "the disciples were first called Christians" according to the biblical Book of Acts, is located in modern Turkey, as are most of the areas visited by St. Paul during his missions. The Epistle to the Galatians, Epistle to the Ephesians, Epistle to the Colossians, First Epistle of Peter, and Book of Revelation are addressed to recipients in the territory of modern Turkey. Additionally, all of the first Seven Ecumenical Councils that define Christianity for Eastern Orthodox Christians and are also considered as foundational by Roman Catholics and some traditional Protestant churches, took place in the territory that is now Turkey.
