Summary: St. Christopher was a member of the north African tribe of the Marmaritae. He was captured by Roman forces during the emperor Diocletian's campaign against the Marmaritae in late 301/early 302 and was transported for service in a Roman garrison in or near Antioch in Syria. He was baptised by the refugee bishop Peter of Alexandria and was martyred on 9 July 308. Bishop Peter arranged for the transport of his remains back to Marmarica in 311. He is really identifiable with the Egyptian martyr known as St. Menas. In so far as the author of the lost, original acts of St. Christopher seems both to have been based at Antioch and to have wanted to encourage missionary activity, he is probably identifiable if not as bishop Theophilus the Indian himself, present at Antioch c.351-54, then as one of his circle.
