Saint Gregory of Neocaesarea, also known as Gregory Thaumaturgus, (c. 205 - 265 AD)
Born at Neo-Casearea (the capital of Pontus, in (Asia Minor) about 213; died there 270-275. Among those who built up the Christian Church, extended its influence, and strengthened its institutions, the bishops of Asia Minor occupy a high position; among them Gregory of Neocaesarea holds a very prominent place. His pastoral work is but little known, and his theological writings have reached us in a very incomplete state. In this semi-obscurity the personality of this great man seems eclipsed and dwarfed; even his immemorial title Thaumaturgus (the wonder-worker) casts an air of legend about him. Nevertheless, the lives of few bishops of the third century are so well authenticated; the historical references to him permit us to reconstruct his work with considerable detail.
