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.
All Commentaries on Luke 2:21 Go To Luke 2
Cyril of Alexandria
AD 444
It was the custom on the eighth day to perform the circumcision of the flesh. For on the eighth day Christ rose from the dead, and conveyed to us a spiritual circumcision, saying, Go and teach all nations, baptizing them.
But according to the command of the law, on the same day He received the imposition of a name, as it follows, His name was called Jesus which is interpreted Savior. For He was brought forth for the salvation of the whole world, which by His circumcision He prefigured, as the Apostle says to the Colossians, “you are circumcised witha circumcision made without hands, in the stripping off of the body of the flesh, to wit, the circumcision of Christ.”
