Clement of Alexandria

"Blessed be the God and Father of our Lord Jesus Christ, who by His great mercy has regenerated us." For if God generated us of matter, He afterwards, by progress in life, regenerated us.

"The Father of our Lord, by the resurrection of Jesus Christ:" who, according to your faith, rises again in us; as, on the other hand, He dies in us, through the operation of our unbelief. For He said again, that the soul never returns a second time to the body in this life; and that which has become angelic does not become unrighteous or evil, so as not to have the opportunity of again sinning by the assumption of flesh; but that in the resurrection the soul returns to the body, and both are joined to one another according to their peculiar nature, adapting themselves, through the composition of each, by a kind of congruity like a building of stones.
