John 5:37

(vi. de Trin. c. 27) But the testimony of works not being sufficient evidence, it follows, And the Father Himself which hath sent Me, hath borne witness of Me. Open the Evangelic volumes, and examine their whole range: no testimony of the Father to the Son is given in any of the books, other than that He is the Son. So what a calumny is it in men now saying that this is only a name of adoption: thus making God a liar, and names unmeaning.

"And the Father Himself, which hath sent Me, hath borne witness of Me." Where did He "bear witness of" Him? In Jordan: "This is My beloved Son, in whom I am well pleased"; hear Him. Yet even this needed proof. The testimony of John then was clear, for they themselves had sent to him, and could not deny it. The testimony from miracles was in like manner clear, for they had seen them wrought, and had heard from him who was healed, and had believed; whence also they drew their accusation. It therefore remained to give proof to the testimony of the Father.

"Ye have neither heard His voice at any time": How then saith Moses, "The Lord spake, and Moses answered"? and David, "He had heard a tongue which he knew not"; and Moses again, "Is there any such people which hath 'heard the voice of God'?" "Nor seen His shape." Yet Isaiah, Jeremiah, and Ezekiel, are said to have seen Him, and many others. What then is that which Christ saith now? He guideth them by degrees to a philosophical doctrine, showing that with God is neither voice nor shape, but that He is higher than such forms or sounds like these. For as when He saith, "Ye have not heard His voice," He doth not mean that God doth indeed utter a voice, but one which cannot be heard; so when He saith, "Nor seen His shape," He doth not mean that God hath a shape though one invisible, but that neither of these things belongeth to God. And in order that they might not say, "Thou art a boaster, God spake to Moses only"; (this at least they did say, "We know that God spake with Moses: as for this fellow, we know not whence He is";) on this account He spake as He did, to show that there is neither voice nor shape with God.

By His mission we must understand His incarnation. Lastly, He shows that God is incorporeal, and cannot be seen by the bodily eye: Ye have neither heard His voice at any time, nor seen His shape.

The Jews might say, We heard the voice of the Lord at Sinai, and saw Him under the appearance of fire. If God then bears witness of Thee, we should know His voice. To which He replies, I have the witness of the Father, though ye understand it not; because ye never heard His voice, or saw His shape.
