«Jesus Christ, our Lord and God, when he was about to offer himself once on the altar of the Cross to God the Father, making intercession by means of his death, so that he might gain there an eternal
redemption, since his priesthood was not to be extinguished by death, at the last Supper, «on the night that he was handed
over», left to his beloved Spouse the Church a visible sacrifice, such as the nature of man requires, by which the bloody sacrifice achieved once upon the Cross might be represented and its memory endure until the end of the age, and its saving power be applied to the remission of those
sins which are daily committed by us.»
There is also much of the Word that suggests (perhaps vaguely and mysteriously) that this
redemption will be complete (not partial; which would suggest the power of
sin, Satan or death will win out
over the majority).
Man was created by God originally to be immortal in both body and soul, but because of his
sin he was declared mortal.44 It was necessary for God to decree the dissolution of the body so that «
sin might be altogether destroyed from the very roots».45 God's plan of the
redemption of man involved a complete remodeling, so that what had been handed
over to death should be rescued for eternity.
