Observe the order which he [Paul] keeps here; for he says, that sin preceded, and that from sin death followed. There are indeed some who contend, that we are so lost through Adam's sin, as though we perished through no fault of our own, but only, because he had sinned for us. But Paul distinctly affirms, that sin extends to all who suffer its punishment: and this he afterwards more fully declares, when subsequently he assigns a reason why all the posterity of Adam are subject to the dominion of death; and it is even this--because we have all, he says, sinned.

But to sin in this case, is to become corrupt and vicious; for the natural depravity which we bring from our mother's womb, though it brings not forth immediately its own fruits, is yet sin before God, and deserves his vengeance: and this is that sin which they call original. For as Adam at his creation had received for us as well as for himself the gifts of God's favor, so by falling away from the Lord, he in himself corrupted, vitiated, depraved, and ruined our nature; for having been divested of God's likeness, he could not have generated seed but what was like himself. Hence we have all sinned; for we are all imbued with natural corruption, and so become sinful and wicked.
