Now, on the eighth day, the Child was circumcised, and was called Jesus. By thus offering His blood so soon for you as a price, He showed Himself to be your true and only Saviour; that the Saviour promised to our forefathers through word and sign, and like unto them in all things save ignorance and sin. For this reason, also, He received the mark of circumcision; that, coming in the likeness of sinful flesh, He might condemn sin in the flesh, and become our Salvation, and our eternal Justification, by beginning His life with an act of humility, the root and guardian of all virtues.
