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.
Or by the sin of the world is meant original sin, which is common to the whole world: which original sin, as well as the sins of every one individually, Christ by His grace remits.
