Our human form hast Thou taken on Thyself without change, O greatly-compassionate Master, though being God by nature; fulfilling the Law, Thou willingly receivest circumcision in the flesh, that Thou mightest end the shadow and roll away the veil of our sinful passions. Glory be to Thy goodness unto us. Glory be to Thy compassion. Glory, O Word, to Thine inexpressible condescension.
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. - Luke 2:21 (KJV)
