John Chrysostom
Catena Aurea · Johannesevangelium 1
And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him. And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost. And I saw, and bare record that this is the Son of God.
(Hom. xvii [al. xvi.] 2. in Joan.) Should any however think that Christ really wanted the Holy Spirit, in the way that we do, he corrects this notion also, by informing us that the descent of the Holy Ghost took place only for the purpose of manifesting Christ: And I knew Him not: but He that sent me tobaptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on Him, the same is He which baptizeth with the Holy Ghost.
