Today Isaiah prophesies that a young woman will bear a son and name him Emmanuel. The gospel is Matthew’s account of the annunciation and birth of the one named Emmanuel, God-with-us. During these final days of Advent we pray, “O come, O come, Emmanuel,” a beloved hymn based on the O Antiphons, ancient prayers appointed for the seven days preceding Christmas. On this final Sunday of Advent we prepare to celebrate the birth of the one born to save us from the power of sin and death.

 

Matthew 1:18-25

18Now the birth of Jesus the Messiah took place in this way. When his mother Mary had been engaged to Joseph, but before they lived together, she was found to be with child from the Holy Spirit. 19Her husband Joseph, being a righteous man and unwilling to expose her to public disgrace, planned to dismiss her quietly. 20But just when he had resolved to do this, an angel of the Lord appeared to him in a dream and said, “Joseph, son of David, do not be afraid to take Mary home as your wife, for the child conceived in her is from the Holy Spirit. 21She will bear a son, and you are to name him Jesus, for he will save his people from their sins.” 22All this took place to fulfill what had been spoken by the Lord through the prophet:
23“Look, the virgin shall conceive and bear a son,
  and they shall name him Emmanuel,”
which means, “God is with us.” 24When Joseph awoke from sleep, he did as the angel of the Lord commanded him; he took her home as his wife, 25but had no marital relations with her until she had borne a son; and he named him Jesus.
