Catholic Mosaic Art Cross Baptism of JesusThis unique mosaic cross celebrates the Baptism of Jesus in the Jordan River by his cousin, St. John the Baptist. This scene heralds the beginning of the public ministry of Christ. The cross features excerpts of the Our Father, the prayer Christ taught us. The Holy Spirit, represented by the dove, gently descends upon Christ as he receives the sacrament. A voice from heaven addresses the crowd, "This is My beloved Son, in whom I am well pleased."
