The Sunday after Christmas Day
Almighty God, who hast given us thy only-begotten Son to take our nature upon him, and as at this time to be born of a pure Virgin: Grant that we being regenerate, and made thy children by adoption and grace, may daily be renewed by thy Holy Spirit; through the same our Lord Jesus Christ, who liveth and reigneth with thee and the same Spirit, ever one God, world without end. Amen.
Now I say, that the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all; but is under tutors and governors, until the time appointed of the father. Even so we, when we were children, were in bondage under the elements of the world: but when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law, to redeem them that were under the law, that we might receive the adoption of sons. And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father. Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ.
St. Matthew 1.18-21
The birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together she was found with child of the Holy Ghost. Then Joseph her husband, being a just man, and not willing to make her a publick example, was minded to put her away privily. But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph thou son of David, fear not to take unto thee Mary thy wife; for that which is conceived in her is of the Holy Ghost: and she shall bring forth a Son, and thou shalt call his name Jesus; for he shall save his people from their sins. (Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying, Behold, a Virgin shall be with child, and shall bring forth a Son, and they shall call his name Emmanuel, which being interpreted is, God with us.) Then Joseph, being raised from sleep, did as the angel of the Lord had bidden him, and took unto him his wife; and knew her not till she had brought forth her first-born son: and he called his name Jesus.
