And when eight days were accomplished for the circumcising of the child, his name was called JESUS, who was so named of the angel before he was conceived in the womb.

Athanasius the Apostolic
AD 373
For circumcision expressed nothing else, but the stripping off of the old birth, seeing that part was circumcised which caused the birth of the body. And thus it was done at that time as a sign of the future baptism through Christ. Therefore as soon as that of which it was a sign came, the figure ceased. For since the whole of the old man Adam is taken away by baptism, there remains nothing which the cutting of a part prefigures.
