3. But if they believe not the Son, let them hear the Father also saying that the Spirit of the Lord is upon Christ. For He says to John: “Upon whomsoever thou shalt see the Spirit descending from heaven and abiding upon Him, He it is Who baptizeth with the Holy Spirit.” S. John i. 33. God the Father said this to John, and John heard and saw and believed. He heard from God, he saw in the Lord, he believed that it was the Spirit Who was coming down from heaven. For it was not a dove that descended, but the Holy Spirit as a dove; for thus it is written: “I saw the Spirit descending from heaven as a dove.” S. John i. 32.
