Diocese of Hierapolis

The diocese of Hierapolis, was a Christian bishopric in Phrygia (modern central Turkey).

Through the influence of the Christian apostle Paul, a church was founded at Hierapolis while he was at Ephesus.

[2] The town's martyrium was alleged to have been built upon the spot where Philip was crucified in AD 80.

[3][4] During the 4th century, Christianity had become the dominant religion and begun suppressing other faiths in the area.

During the Byzantine period, the city continued to flourish and also remained an important centre for Christianity.
