The birth of Jesus Christ occurred in this way. When his mother Mary was engaged to Joseph, but before they came to live together, she was found to be with child through the Holy Spirit.
While they were there, the time came for her to have her child, and she gave birth to her firstborn son. She wrapped him in swaddling clothes and laid him in a manger, because there was no room for them in the inn.
Therefore, you will be given this sign by the Lord himself: The virgin will be with child, and she will give birth to a son, and she will name him Immanuel.
Blessed be the God and Father of our Lord Jesus Christ. In his great mercy he has given us a new birth to a living hope through the resurrection of Jesus Christ from the dead.
All this took place in order to fulfill what the Lord had announced through the prophet: “Behold, the virgin shall conceive and give birth to a son, and they shall name him Emmanuel,” a name that means “God is with us.”
We ourselves are Jews by birth and not Gentile sinners, yet we know that a man is justified not by the works of the Law but through faith in Jesus Christ. So we too came to believe in Christ Jesus so that we might be justified by faith in him and not by the works of the Law, for no one will be justified by the works of the Law.
Then the angel said to her, “Do not be afraid, Mary, for you have found favor with God. Behold, you will conceive in your womb and bear a son, and you will name him Jesus.”
