Life That Begins with Mercy
In today’s Gospel, Matthew tells the story not from Mary’s point of view, but from Joseph’s. Luke stays close to Mary. Matthew invites us to stay with Joseph, to watch him, to listen to what is happening in his heart. Mary was engaged to Joseph. They were not yet living together. Then her pregnancy became known. The Gospel tells us that the child was conceived by the Holy Spirit. But Joseph did not know that. And in that society, this was not a small misunderstanding. Pregnancy during engagement was a valid reason to end the engagement. And under the Law, an engaged woman judged to have been unfaithful could face public shame and severe punishment (Deuteronomy 22:23–24). Joseph could have accused Mary publicly. He could have protected himself by exposing her. Mary’s life could have collapsed in an instant.
But Scripture describes Joseph in this way: “Her husband Joseph, being a righteous man and unwilling to expose her to public disgrace, planned to dismiss her quietly” (Matthew 1:19). This phrase—“a righteous man”—matters. It does not mean that Joseph simply followed the letter of the Law. Rather, it points to his understanding of the spirit of the Law: mercy and compassion.
Joseph could have insisted on his rights. According to the Law, he could have accused Mary publicly. Yet he chose not to do so. As far as the situation allowed, he tried not to push her into greater danger or deeper shame. For that reason, he decided to end the engagement quietly.
This was not a heroic decision. It was a pause, a refusal to allow the situation to turn violent. Joseph did not understand everything, nor had he let go of everything. Still, he chose not to create a deeper wound.
It is precisely here that God’s work begins. God does not act only through perfect people, but through small pauses, through narrow spaces where harm is restrained and mercy is allowed to breathe.
While Joseph was turning these things over in his mind, God spoke to him through a dream. “Joseph, son of David, do not be afraid to take Mary as your wife, for the child conceived in her is from the Holy Spirit.” (Matthew 1:20) Notice where God speaks. God does not break into Joseph’s life with violence or pressure. God speaks right in the center of Joseph’s struggle—in the place where mercy has already made room. God does not force the heart open. God enters a heart that is already opening through compassion. And the angel continues: “She will bear a son, and you are to name him Jesus, for he will save his people from their sins.” (Matthew 1:21)
The name Jesus means, “God saves.” And Matthew is clear: this saving work does not begin with power. It does not begin with control. It does not begin with force. It begins with mercy. Joseph’s merciful decision did not only protect one woman or one household. It became part of the beginning of salvation for the world. Mercy made space for life.
Today we also heard Isaiah’s words: “Look, the young woman is with child and shall bear a son, and shall name him Immanuel.” (Isaiah 7:14) Immanuel means: “God is with us.” Matthew tells us that this promise is fulfilled in 1
the birth of Jesus. God is not distant. God does not remain safely above human weakness and confusion. God comes near—into fear, into hesitation, into the complicated places where people do not know what to do. Joseph’s heart was exactly such a place.
And Jesus is truly Emmanuel, God with us. Not only “with us” when we are strong and faithful, but “with us” in the very places where life feels fragile and choices feel heavy. Matthew also makes a quiet point: when Joseph takes Mary as his wife, Jesus becomes, within the story’s legal and social world—a son of David. Joseph’s obedience, and Joseph’s protection, become part of how the promise is carried forward.
The early Church did not see this as only one family’s unusual story. They confessed it as the fulfillment of a promise God had spoken long ago. Paul writes in Romans: “the gospel concerning his Son, which he promised beforehand through his prophets in the holy scriptures.” (Romans 1:2–3a) The birth of Jesus is the fulfillment of a long promise. And in today’s Gospel, that promise becomes real through the merciful decision of one person.
Paul also speaks of Jesus as one “descended from David according to the flesh.” (Romans 1:3) Behind that short phrase stands Joseph, the one who welcomed Mary, the one who gave Jesus a place, the one who chose mercy when he could have chosen accusation.
When Joseph wakes from his dream, he accepts what has been entrusted to him as God’s will. He takes Mary as his wife. This was not an easy choice. It meant letting go of his honor. It meant carrying misunderstanding. It meant trusting God more than his own plan. And this is an important Advent truth: Christmas does not come only through the courage of great heroes. God brings life through quiet mercy—through hearts that choose to protect rather than expose. Mercy gives birth to life. Mercy becomes the path through which God’s work is done. When mercy lives in us, God’s life can be revealed through us.
On this final Sunday of Advent, we ask ourselves: What does it mean to wait for the Lord? We often speak of Mary’s faith, and we should. But Matthew asks us to see Joseph as well. Mary’s obedience and Joseph’s mercy belong together. A heart that listens to God’s word, and a heart that protects and embraces others—both are part of the way God comes near.
And on this last Sunday of Advent, this season does not ask us to make a show of our faith. We are invited to prepare our hearts. A heart where the Lord may enter. A heart where life may rest. A heart where compassion moves first. Our faith, like Joseph’s righteousness, should not stop at rules and forms. We are called to live with mercy and grace. And when we choose to protect rather than judge, to embrace rather than condemn, we become instruments of God’s work.
As Christmas draws near, we make room for Emmanuel, Jesus, God with us. Like Joseph, we let go of fear and trust God’s will. This is how Emmanuel comes to us: through mercy, through obedience, through hearts that remain open. And when we welcome him in this way, new life will begin, within us, and through us. Amen.
