'''Efes''' (gr. Ἔφεσος) a fost un important centru al creștinătății timp de multe secole. The city, in western Asia Minor, was a significant center along the [[missionary]] travels of [[Apostle Paul]] during the first century. The Christians of Ephesus were recipients of one of Paul’s letter as well as one from St. [[Ignatius]] in the second century. Ephesus was one of the seven cities mentioned in [[Book of Revelation]]. It was the site of the [[Third Ecumenical Council]] in 431, and it was the [[see]] of St. [[Mark of Ephesus]] in the fifteenth century.
