Theophylact of Ohrid
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.
The Father then hath given all things to the Son in respect of His divinity; of right, not of grace. Or; He hath given all things into His hand, in respect of His humanity: inasmuch as He is made Lord of all things that are in heaven, and that are in earth.
