This text, which appears immediately after the genealogy of Jesus, and is the Gospel text for today, narrates the story of his birth. Since Mary and Joseph were engaged, they were legally considered husband and wife. Thus, infidelity in this case would also be considered adultery. Their union could only be dissolved by divorce or death. Though Joseph is righteous or just, he decides not to go by the letter of the law and publicly disgrace Mary, but he chooses a quieter way of divorcing her. God, however, has other plans for both Joseph and Mary and intervenes in a dream. Joseph is addressed by the angel as “Son of David” reiterating, once again after the genealogy, the Davidic origin of Jesus. He is asked to take Mary as his wife and also informed that is the Spirit’s action that is responsible for her pregnancy. He is told that he is to give the child the name “Jesus". Jesus (Iesous) is the Greek form of "Joshua" which, whether in the long form yehosua, ("Yahweh is salvation") or in one of the short forms, yesua, ("Yahweh saves”), identifies the son, in the womb of Mary, as the one who brings God’s promised eschatological salvation. The angel explains what the name means by referring to Ps 130:8. The name “Jesus” was a popular and common name in the first century. By the choice of such a name, Matthew shows that the Savior receives a common human name, a sign that unites him with the human beings of this world rather than separating him from them.
Matthew then inserts into the text the first of ten formula or fulfillment quotations that are found in his Gospel. This means that Matthew quotes a text from the Old Testament to show that it was fulfilled in the life and mission of Jesus. Here, the text is from Isa 7:14 which, in its original context, referred to the promise that
This birth narrative of Matthew invites us to reflect on a number of points. Of these, two are significant. First, many of us are often caught in the dilemma of doing the right thing which might not always be the loving thing. If we follow only the letter of the law, we may be doing the right thing but not the most loving thing. However, if we focus every time on the most loving thing, like Joseph, it is surely also the right thing. Though Joseph could have done the right thing and shamed Mary by publicly divorcing her, he decides to go beyond the letter of the law and do the loving thing, which in his case was also the right thing.
Second, the story also shows us who our God is. Our God is God with us. Our God is one who always takes the initiative, who always invites, and who always wants all of humanity to draw closer to him and to each other. This God does not come in power, might, and glory, but as a helpless child. As a child, God is vulnerable. He is fully human and in his humanity, is subject to all the limitations that humanity imposes on us. Yet, he will do even that, if only humans respond to the unconditional love that he shows.
