Jesus Christ, as the Son of God, lived a perfect mortal life as an exemplar for mankind, including His baptism. He prioritizied the will of the Father over His own needs. He established the foundations of His church through the calling of apostles and the institution of the sacrament. Ultimately, His unique mission was to redeem mankind from physical and spiritual death through His suffering in Gethsemane, His sacrifice on the cross, and His victorious resurrection.
