So Christ grew after the flesh, and was baptized in order that He who was to give the form of baptism to others should first Himself receive what He taught. But after His baptism He chose twelve disciples, one of whom betrayed Him. And because the people of the Jews would not bear sound doctrine they laid hands upon Him and slew and crucified Him. Christ, then, was slain; He lay three days and three nights in the tomb; He rose again from the dead as He had predetermined with His Father before the foundation of the world; He ascended into heaven whence we know that He was never absent, because He is Son of God, in order that as Son of God He might raise together with Him to the heavenly habitation man whose flesh He had assumed, whom the devil had hindered from ascending to the places on high. Therefore He bestowed on His disciples the form of baptizing, the saving truth of the teaching, and the mighty power of miracles, and bade them go throughout the whole world to give it life, in order that the message of salvation might be preached no longer in one nation only but among all the dwellers upon earth. And because the human race was wounded by the weapon of eternal punishment by reason of the nature which they had inherited from the first transgressor and could not win a full meed of salvation because they had lost it in its first parent, God instituted certain health- giving sacraments to teach the difference between what grace bestowed and human nature deserved, nature simply subjecting to punishment, but grace, which is won by no merit, since it would not be grace if it were due to merit, conferring all that belongs to salvation.
