The church in Antioch was the first to be called "Christian," according to Acts. According to tradition, Saint Peter established the church and was the city's first bishop, before going to Rome to found the Church there. Ignatius of Antioch (died c. 107), counted as the third bishop of the city, was a prominent apostolic father. By the fourth century, the bishop of Antioch had become the most senior bishop in a region covering modern-day eastern Turkey, Lebanon, Israel and Palestine, Syria, Jordan, Iraq, and Iran. His hierarchy served the largest number of Christians in the known world at that time. The synods of Antioch met at a basilica named for Julian the Martyr, whose relics it contained.
