John Chrysostom
Catena Aurea · Johannesevangelium 1
And they which were sent were of the Pharisees. And they asked him, and said unto him, Why baptizest thou then, if thou he not that Christ, nor Elias, neither that prophet? John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not; He it is, who coming after me is preferred before me, whose shoe’s latchet I am not worthy to unloose. These things were done in Bethabara beyond Jordan, where John was baptizing.
(Hom. xvi. [al. xv.] 3) As if he said, Do not think that every thing is contained in my baptism; for if my baptism were perfect, another would not come after me with another baptism. This baptism of mine is but an introduction to the other, and will soon pass away, like a shadow, or an image. There is One coming after me to establish the truth: and therefore this is not a perfect baptism; for, if it were, there would be no room for a second: and therefore he adds, Who is made before me: i. e. is more honourable, more lofty.
