Sisinnius
[[1] This Elpidius had a disciple, by name Sisinnius, of servile origin, but a free man as regards the faith, a Cappadocian by race. For one must point out these things for the glory of Christ, Who ennobles us and leads us to the true nobility. After dwelling with Elpidius six or seven years finally he shut himself up in a tomb and continued for three years in a tomb, praying constantly, sitting down neither by night nor day, neither lying down nor walking out. He was counted worthy of a gift (of power) over demons. [2] But having returned to his native country he was counted worthy of the priesthood, and collected a community of men and women. By his grave manner of life he drove out whatever masculine lusts there were in himself, and by self-discipline he curbed the feminine element in the women, so that the words of Scripture were fulfilled: “In Christ Jesus there is neither male nor female.” Then also he is hospitable, although without possessions, so as to shame the rich men who are not generous.]
