If I bear witness of myself, my witness is not true.
All Commentaries on John 5:31 Go To John 5
Cyril of Alexandria
AD 444
The most wise Solomon, gathering together the things in which a man may very reasonably glory, and shew his manner of life to be enviable, and placing them before those who are apt to learn, says, The righteous man is his own accuser in the opening of the trial, and again, Let thy neighbour praise thee and not thine own mouth, a stranger and not thine own lips. For a thing truly burdensome and most intolerable to the hearers, is it that some like not to be praised by the voice of others, but attest unrestrainedly their own most noble and excellent deeds. But with reason is such language distrusted; for we are wont to be invited by certain (so to speak) natural and necessary drawings of self-love, readily to ascribe to ourselves nought that is ill, but ever to put about us and not altogether truthfully, the things whereby any may be thought well-behaved and good.
When then our Lord Jesus Christ adjudged to Himself that He judgeth righteous judgments, saying openly that He could do nothing of Himself, but that He makes the Will of the Father His Rule in all His Actions, and in saying this, introduced Himself as witness to Himself, although it was true, yet of necessity considering the sophistry of the Pharisees, and what they would say in their folly (for they knew not that He is God by Nature): He anticipates them in putting it forward, and says, Ye following the practice of the common people, and not advancing beyond surmise befitting Jews, will surely say, THOU bearest record of Thyself, Thy record is not true; but ye shall hear this in reply (saith He), I endure yet with your blasphemies, I am by no means exceeding angry with you belching forth your words from the ignorance most dear to you, I grant you for argument's sake, that even this hath been well said by you: Be it so, ye reject My Voice, there is Another That beareth witness of Me. He here indicates God the Father Which is in heaven Who hath now in divers manners attested the Verity of the Essence of His Own Son; and He says that He knows that His witness is True shewing that His Own Judgement too is in fact most trustworthy and true. For lest by admitting as it were that He said things untrue of Himself, He should give room for malice, and a loophole against Himself to them who are accustomed to think otherwise, He having ceded of necessity to what is becoming and customary, that one ought not altogether to credit as true him who praises and approves himself, returns again as God to His due position and says that He knows that the witness of the Father is true, all bat teaching this; I being Very God know Myself (says Ho), and the Father will say nothing of favour concerning Me. For I am Such by Nature, as He, being True, will declare Me. In the former part then there was an assent so to say of condescension, and the words hypothetic rather than true; in His saying that He knows that the witness of the Father is true, is the demonstration of God-befitting credibility.
But it must be observed that in respect of His Own Person the Father is Other than the Son, and is not, as some uninstructed heretics have imagined, introduced as the Son-Father.
