Petra
The “rose-red city” of Petra in southern Jordan, famous for its rock-cut monumental buildings, was once the setting for a thriving Christian community with several significant churches. An early account tells of Christians in Petra being martyred during the persecution of emperor Diocletian at the beginning of the 4th century, for refusing to offer sacrifice to Roman gods. Nevertheless, a Christian presence persisted. Bishops from Petra attended Church synods and councils from AD 343, indicating that the city had become a significant Christian centre.
The greatest Nabataean king was Aretas IV (9 BC to AD 40), whose rule extended as far north as Damascus. His daughter Phasaelis was married to Herod Antipas, who divorced her to marry Herodias, his brother’s wife. Aretas IV then marched on Herod’s army, defeated it and captured territories along the West Bank of the Jordan River.
