Today’s celebration of the Solemnity of the Baptism of the Lord comes with options for the first and second readings. The first readings are from different parts of the Prophet Isaiah. One echoes the words that the Father speaks at Jesus’ baptism and the other echoes the Gospel (quoting Isaiah) from the second Sunday of Advent—make straight the paths of the Lord. The second readings include a speech from Peter as he is about to baptize the household of a pagan who received the Holy Spirit and a teaching on the free gift of salvation that Jesus offers each of us—not through our own earning, but through our acceptance of Christ’s charitable love toward us. The Gospel is Luke’s version of the Baptism, in which we see Father, Son, and Holy Spirit all present together at once—the Trinity revealed. It is the moment that a symbolic ritual became reality. It is the moment that God chooses to introduce himself to each of us personally—that we become adopted children of God and receive our vocation to be priest, prophet and king.
