Monk in Caesarea, Cappadocia. May have been a priest; records are unclear. He was one of a group of Christians assembled and ordered to make a sacrifice to idols during the persecutions of Diocletian; when the sacrificial fire went out, Sergius immediately claimed it was the work of the true God. He was immediately “tried” and executed by order of the local governor. Martyr.
