Much has been said about this passage from Isaiah regarding its original significance in the time and place in which it was written. Although modern scholars have noted that the Hebrew term translated as “virgin” (almah) isn’t the technical word for virgin—the word means a young woman of marriageable age—such a woman would ordinarily be understood to be a virgin. This understanding is reflected in the Septuagint, the ancient Greek version of the Old Testament, which uses the term parthenos—a word that ordinarily means "virgin."
The tradition of the Church is unanimous that Mary and her virginal conception fulfill this passage from Isaiah the prophet. In Matthew 1:22–23, the Evangelist, working under the direct inspiration of the Holy Spirit, cites this passage from Isaiah and declares that it was fulfilled in the announcement of the birth of Jesus made to St. Joseph by an angel. It wasn’t until the mid-eighteenth century that the Magisterium (Pius VI had to condemn an interpretation to the contrary.
The Vatican II document Lumen Gentium also identifies the young woman spoken of in Isaiah 7 as the Virgin Mary and makes a further connection with “the woman” mentioned in Genesis 3:15 who would ensure the victory over the serpent (LG, 55). Without any other credible candidates for almah and in the face of the consistent teaching of the Scripture and the Church, we can feel utterly confident that the woman prophesied is indeed Mary, Mother of Immanuel.
S t. Paul provides a wonderful link between the first reading from the Old Testament and the Gospel reading. On this Fourth Sunday of Advent, we stand at the very cusp of the event that we call the Incarnation, which is fully disclosed in a beautiful way on the Feast of the Nativity that we call Christmas. Joseph is the “son of David,” and so through him the prophecy of Isaiah to the “house of David” can be fulfilled. Emmanuel, “God is with us,” was with Joseph, the son of David, when in obedient and trusting faith he “received [Mary] into his home.” In receiving Mary, he also received Jesus, who was already within her womb by the power of the Holy Spirit.
That’s why Mary figures so prominently in a Catholic Advent. She’s the bearer of Emmanuel. God first takes up his dwelling in her. She’s the model in the flesh of the Church that receives the indwelling of the Savior in his flesh. If the core of the Catholic faith is expressed in the name Emmanuel, the “dwelling with us” is best shown in the persons of Mary, who received him into her womb, and Joseph, who received her into his home, the house of David
This Gospel passage features that mysterious name “Emmanuel,” which we apply to our Savior, Jesus Christ. It literally means “with us is God.” In that name is a capsule description of our Catholic faith. The single difference between Christianity and all other religions is that God has come to dwell among us as a manWhile both Catholics and Protestants believe that Christ came in the flesh, we believe that he also left us his flesh, as promised in John 6 and Matthew 28:20, so that he could remain with us until the end of time. The whole of Catholic life centers on the belief that God has come into our midst and remains among us. The Sacraments make Christ present to us, particularly the Eucharist, which effects what we call His Real Presence among us: Body, Blood, Soul, and Divinity. We could say that “Emmanuel” is another word for Incarnation. It’s only in carne, in the flesh, that God could dwell with us in that kind of intimacy— that’s at the very heart of Christian faith and the life of sanctity { which expresses that faith
Imagine that you are with Joseph when he awakens from his dream. He tells you that even though Mary is pregnant, he is going to marry her anyway because the child she is carrying is the longawaited Messiah, who will save his people from their sins. What do you think when you hear this? Are you shocked at his decision, or inspired by his trust in the Lord? Do you think you would have the courage to do what Joseph did? Prayerfully reflect on how you tend to respond when God invites you to do something difficult or confusing.
RESOLUTION:
Is there an area of your life right now that is bewildering or difficult for you to understand—an area in which you may be wondering, “Why is this happening? What am I to do? Where is God in all of this?” Take this situation to God in prayer. Talk to God about it. Ask him to show you what he is trying to teach you through this difficult situation, and then ask him to help you imitate Joseph’s trust and obedience.
