With the spread of Christianity Coracesium, as it was called, became a bishopric. Its bishop Theodulus took part in the First Council of Constantinople in 381, Matidianus in the Council of Ephesus in 431, Obrimus in the Council of Chalcedon in 451, and Nicephorus (Nicetas) in the Third Council of Constantinople in 680. Coracesium was a suffragan of the metropolitan see of Side, the capital of the Roman province of Pamphylia Prima, to which Coracesium belonged. It continued to be mentioned in the "Notitiae Episcopatuum" as late as the 12th or 13th century. No longer a residential bishopric, Coracesium is today listed by the Catholic Church as a titular see.
