The Feast of the Circumcision of Our Lord is a Christian celebration of the circumcision of Jesus, eight days (according to the Semitic and southern European calculation of intervals of days) after his birth, the occasion too on which the child was formally given his name, Jesus, a name derived from Hebrew meaning "salvation" or "saviour".
Propers for the Naming of Jesus or the Circumcision of Christ.
ALMIGHTY God, who madest thy blessed Son to be circumcised, and obedient to the law for man; Grant us the true circumcision of the Spirit; that, our hearts, and all our members, being mortified from all worldly and carnal lusts, we may in all things obey thy blessed will; through the same thy Son Jesus Christ our Lord. Amen.
The Epistle - Philippians ii. 9.
GOD also hath highly exalted him, and given him a name which is above every name: that at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. For it is God which worketh in you both to will and to do of his good pleasure.
The Gospel - St. Luke ii. 15.
AND it came to pass, as the angels were gone away from them into heaven, the shepherds said one to another, Let us now go even unto Bethlehem, and see this thing which is come to pass, which the Lord hath made known unto us. And they came with haste, and found Mary, and Joseph, and the babe lying in a manger. And when they had seen it, they made known abroad the saying which was told them concerning this child. And all they that heard it wondered at those things which were told them by the shepherds. But Mary kept all these things, and pondered them in her heart. And the shepherds returned, glorifying and praising God for all the things that they had heard and seen, as it was told unto them. 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.
