According to
Dorotheus of Tyre, the first bishop was a certain
Philemon who was believed to have been one of the
seventy disciples of
Jesus and was mentioned by
St. Paul. An early bishop called
saint Silvanus (not to be confused with
Abba Silvanus) is said to have been killed with thirty-nine other
martyrs in the copper mines of Phaeno around the year 310. In the early 4th century,
the emperor Constantine endowed the town of
Maiuma, which formerly had served as Gaza's harbour, with city rights and the status of an episcopal see. Though its city rights were cancelled later, it remained its own bishopric. The first attested bishop is Asclepias (also Asclepas) of Gaza who is known to have attended the
First Council of Nicaea in 325. As an ardent supporter of
Athanasius of Alexandria, he was deposed around the year 326 or 327, but was later reinstated at the
council of Serdica while Quintianus, who in the meantime had usurped the episcopal see, was
excommunicated. As Gaza was still fairly pagan, Asclepias constructed an
oratory, later referred to as "Old Church", to the west of the city. His successor Irenaeus seems to have been able to erect a small church in the city, attended the council of Antioch in 363 and is commemorated as a saint. Under
Porphyrius, who became bishop around the year 395, the temple of
Marnas and all other pagan temples of the town were closed and destroyed. His successor Netoras attended the
council of Ephesus and the council of Chalcedon. The next bishop, Cyril, attended a council in Jerusalem in 518. Quite exceptionally, Marcianus also headed the school for a time, possibly until a "full-time professor" could be found to fill the position. Marcianus commissioned churches, walls,
stoas and bathhouses, defended the citizens from being exploited by soldiers, operated social welfare for the benefit of the poor and went to
Constantinople as diplomatic representative of his town. Marcianus was also in close contact with the monastic communities around the town, especially those of the
monastery of Seridus. He regularly sought advice from the two hermits
Barsanuphius and
John the Prophet, such as on who to ordain as priest. Marcianus also attended the
council of Jerusalem in 536. == Middle Ages==
