5Epistle. Rom. i. 1—6. Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God, which he had promised before by his prophets in the holy scriptures, concerning his Son, who was made to him of the seed of David according to the flesh, who was predestinated the Son of God in power according to the spirit of sanctification, by the resurrection of our Lord Jesus Christ from the dead, by whom we have received grace and apostleship for obedience to the faith in all nations for his name, among whom are you also the called of Jesus Christ.
7[If this Vigil fall on a Sunday, the following is added:]
9Gospel. St Matt. i. 18—21. When Mary, the mother of Jesus, was espoused to Joseph, before they came together, she was found with child, of the Holy Ghost. Whereupon Joseph her husband, being a just man, and not willing publicly to expose her, was minded to put her away privately. But while he thought on these things, behold the Angel of the Lord appeared to him in his sleep, saying: Joseph, 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.
10Offertory. Lift up your gates, O ye princes, and be ye lifted up, O eternal gates: and the King of glory shall enter in.
11Secret. Grant us, we beseech thee, O Almighty God; that as we anticipate the adorable nativity of thy Son, so we may joyfully receive his eternal benefits. Who lives and reigns, &c.
