“Through His Resurrection, Christ put an end to death, changing it into a necessary passage to immortality. Seen in this perspective, death frees us from the demands and conditions of the fall. Death, the fruit of corruption and “corruptibility,” allows us to move beyond time, which in turn abolishes the corruptibility of death. There is one condition, however: that this movement be an entrance into the Kingdom already present in this world. This is what allows Death to open onto eternity.
According to St. Irenaeus of Lyons:
This is why God cast [Adam] out of Paradise and sent him far from the tree of life; not because He kept this tree of life form him out of jealousy, as some have dared to maintain, but He acted out of compassion, so that man might not remain in sin forever, so that the sin which weighed him down might not be immortal, so that evil might not be without end and thus without remedy. He kept him from his transgression, therefore, by introducing death…giving him an end through the dissolution of the flesh which would take place in the earth so that man, having “died to sin” [Rom 6:2], might be “alive to God” (Adv. Haer., III, 23, 6).
Through His Incarnation, the Logos of creation penetrated matter, His own work. The Infinite became incarnate and subject to space; the Eternal entered time. By coming into the world Christ transformed time and space, effecting a revolution with profound consequences. As God-Man He did not merely assume the corporeal limitations of our condition, He surpassed them. Destined to die by virtue of His Incarnation, whereby He entered into time and space, the crucified Christ bears the suffering and death of every person throughout time and space. Through His Ascension and Resurrection, He leads us beyond the cycle of time, to the never-setting sun.”
