Feast of the Circumcision of Our Lord (Octave Day of Christmas)
The Circumcision, by Luca Signorelli
And after eight days were accomplished, that the child should be circumcised, his name was called JESUS, which was called by the angel, before he was conceived in the womb.
-Luke 2: 21
O God, who, by the fruitful virginity of blessed Mary, hast bestowed upon mankind the rewards of eternal salvation, grant, we beseech Thee, that we may evermore experience the intercession in our behalf of her through whom we have been found worthy to receive the author of life, Our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, God, world without end. Amen.
