All of the first seven Ecumenical Councils which are recognized by both the Western and Eastern churches were held in present-day Turkey. Of these, the Nicene Creed, declared with the First Council of Nicaea (İznik) in 325, is of utmost importance and has provided the essential definitions of present-day Christianity.
Today the Christian population of Turkey includes an estimated 45,000 Armenian Orthodox[2], 17,000 Assyrian- Syriac Orthodox, 8,000 Assyrians of the Chaldean Catholic, 3,000-4,000 Greek Orthodox[3], and smaller numbers of Bulgarians, Georgians, and Protestants.
