Catena Aurea · Johannesevangelium 1
The next day John seeth Jesus coming to him, and saith, Behold the Lamb of God, which taketh away the sin of the world. This is he of whom I said, After me cometh a man which is preferred before me: for he was before me. And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water.
(Moral. viii. c. 32) But then only will sin be entirely taken away from the human race, when our corruption has been turned to a glorious incorruption. We cannot be free from sin, so long as we are held in the death of the body.
