John Chrysostom
Catena Aurea · Johannesevangelium 3
—and no man receiveth his testimony. He that hath received his testimony hath set to his seal that God is true. For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him. The Father loveth the Son, and hath given all things into his hand. He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
(Hom. xxx. 2) By Spirit here is meant the operation of the Holy Spirit. He wishes to shew that all of us have received the operation of the Spirit by measure, but that Christ contains within Himself the whole operation of the Spirit. How then shall He be suspected, Who saith nothing, but what is from God, and the Spirit? For He makes no mention yet of God the Word, but rests His doctrine on the authorityof the Father and the Spirit. For men knew that there was God, and knew that there was the Spirit, (although they had not right belief about His nature;) but that there was the Son they did not know.
