Acts 9:17-18 The Christian signs of baptism appeared in the catacombs of Rome shortly after the time of Christ. Engraved in stone, these symbols picture the convert reviving God’s mercy and accepting new values of living. The symbols included in the window show the descending dove of the Holy Spirit (top), the red cross for Christ’s love and the scallop shell dripping drops of water for baptism, the sign of God’s grace at work, claiming human beings as the children of God. To this day, baptism marks a public pronouncement of faith, an understanding that the baptized belongs to the family of God. At his baptism, St. Paul presented himself for obedient service in God’s Kingdom and received power. Likewise, the believer who seeks God’s will accepts abundant love and vitality to live as God call us to live.
