Joseph is an upright person but his rectitude goes well beyond that of scru-pulously observing the law. He is upright because, contemplating God at work in the events of history, he has the courage to step aside so that Mary is free to say yes to God. He is obedient to the consequence of the Spirits work in Mary and allows God to continue to be the Father who is capable of calling into existence what does not yet exist (cf. Rm. 4:17), just as he did at the beginning of the world: In the beginning, God created (Gn. 1:1).
And God creates through the womb of a woman and the heart of a man whose duty is to give the Child a name: She will bear a son and you are to name him Jesus (Mt. 1:21). Joseph is ordered to give the Child the name chosen for him by God.
This act makes Joseph a father. A father is a person who loves God so much that he becomes his voice and instrument for all those entrusted to his care. Joseph, a descendant of David, was born to tell the world that God is named Jesus, which means love that saves. This name is Josephs gift to us. Jesus is the sole word implicitly spoken by him in the Gospel. The rest is absolute silence. The truth of Joseph is enclosed in the name that is above every name (Phil. 2:9), announced by the prophets (cf. Is. 7:14), bequeathed by the apostles: I have neither silver nor gold, but I will give you what I have: in the name of Jesus Christ the Nazarene, walk! (Acts 3:6). In Jesus, God becomes Emmanuel: God with usa God who is present and who saves us in every place and time.
