John 8:17

What would the heretics say here? (They would say,) "How is he better than man, if we take what he hath said simply? For this rule is laid down in the case of men, because no man by himself is trustworthy. But in the case of God, how can one endure such a mode of speaking? How then is the word 'two' used? Is it because they are two, or because being men they are therefore two? If it is because they are two, why did he not betake himself to John, and say, I bear witness of myself, and John beareth witness of me? Wherefore not to the angels? Wherefore not to the prophets? For he might have found ten thousand other testimonies." But he desireth to show not this only that there are Two, but also that they are of the same Substance.

"I am One that bear witness of Myself; and the Father that sent Me beareth witness of Me." Had He been of inferior substance, He would not have put this. But now that thou mayest not deem that the Father is included, to make up the number (of two), observe that His power hath nothing different (from the Father's). A man bears witness when he is trustworthy of himself, not when he himself needs testimony, and that too in a matter pertaining to another; but in a matter of his own, where he needs the witness of another, he is not trustworthy. But in this case it is all contrary. For He though bearing witness in a matter of His own, and saying that He is borne witness to by another, asserteth that He is trustworthy, in every way manifesting His independence.

For why, when He had said, "I am not alone, but I and the Father that sent Me," and, "The testimony of two men is true," did He not hold His peace, instead of adding, "I am One that bear witness of Myself"? It was evidently to show His independence. And He placeth Himself first; "I am One that bear witness of Myself." Here He showeth His equality of honor.

He had spoken of judgment; He means to speak of testimony. "In your law," saith He, "it is written that the testimony of two men is true. I am one that bear witness of myself, and the Father that sent me beareth witness of me." He expounded the law to them also, if they were not unthankful. For it is a great question, my brethren, and to me it certainly appears to have been ordained in a mystery, where God said, "In the mouth of two or three witnesses every word shall stand." Is truth sought by two witnesses? Clearly it is; so is the custom of mankind: but yet it may be that even two witnesses lie. The chaste Susanna was pressed by two false witnesses: were they not therefore false because they were two? Do we speak of two or of three? A whole people lied against Christ. If, then, a people, consisting of a great multitude of men, was found a false witness, how is it to be understood that "in the mouth of two or three witnesses every word shall stand," unless it be that in this manner the Trinity is mysteriously set forth to us, in which is perpetual stability of truth? Dost thou wish to have a good cause? Have two or three witnesses,-the Father, Son, and Holy Ghost. In short, when Susanna, the chaste woman and faithful wife, was pressed by two false witnesses, the Trinity supported her in her conscience and in secret: that Trinity raised up from secrecy one witness, Daniel, and convicted the two. Therefore, because it is written in your law that the witness of two men is true, receive our witness, lest ye feel our judgment. "For I," saith He, "judge not any man; but I bear witness of myself:" I defer judgment, I defer not the witness. Let us, brethren, choose for ourselves God as our judge, God as our witness, against the tongues of men, against the weak suspicions of mankind. For He who is the judge disdains not to be witness, nor is He advanced in honor when He becomes judge; since He who is witness will also Himself be judge. In what way is He witness? Because He asks not another to learn from Him who thou art. In what way is He judge? Because He has the power of killing and making alive, of condemning and acquitting, of casting down into hell and of raising up into heaven, of joining to the devil and of crowning with the angels. Since, therefore, He has this power, He is judge. Now, because He requires not another witness that He may know thee; and that He who will hereafter judge thee is now seeing thee, there is no means whereby thou canst deceive Him when He begins to judge. For there is no furnishing thyself with false witnesses who can circumvent that judge when He shall begin to judge thee. This is what God says to thee: When thou despisedst, I did see it; and when thou believedst not, I did not frustrate my sentence. I delayed it, not removed it. Thou wouldst not hear what I enjoined, thou shalt feel what I foretold. But if thou hearest what I enjoined, thou shalt not feel the evils which I have foretold, but thou shalt enjoy the good things which I have promised.

Likewise, let it not surprise you that He says, "In your law it is written that the testimony of two men is true," that any man should hence suppose that this was not also the law of God, because it is not said, In the law of God: let him know that, when it is said thus, In your law, it is just as if He said, "In the law which was given to you;" given by whom, except by God? Just as we say, "Our daily bread;" and yet we say, "Give us this day."
