Epiphanius of Salamis
Catena Aurea · Lukasevangelium 2
And when eight days were accomplished for the circumcising of the child, his name was called JESUS, which was so named of the angel before he was conceived in the womb.
(lib. i. Hær. 30.) Now the followers of Ebion and Cerinthus say e, “It is enough for a disciple if he be as his Master. But Christ circumcised Himself. Be thou therefore circumcised.” But herein do they deceive themselves, destroying their own principles; for if Ebion should confess that Christ as God descended from heaven and was circumcised on the eighth day, it might then afford the ground of an argument for circumcision; but since he affirms Him to be mere man, surely as a boy he cannot be the cause of Himself being circumcised, as neither are infants the authors of their own circumcision. But we confess that it is God Himself who has descended from heaven, and that inclosed in a virgin’s womb, He abode there the whole time necessary for her delivery, until He should perfectly form to Himself of the virgin’s womb a human body; and that in this body He was not in appearance but truly circumcised on the eighth day, in order that the figures having come to this spiritual fulfilment, both by Himself and His disciples, might now be spread abroad no longer the figures but the reality.
