John 8:14

On Christ saying that He is what He is by Nature and truly (for He openly declared, I am the Light of the world) the multitude of the Pharisees unrecking of danger deemed that He spake falsely. For in their exceeding folly they knew not that when some set forth their own nature and tell what is essentially inherent in them, we shall not, if we think aright, suppose that they do so out of boasting, nor shall we say that they are bent on hunting vain-glory, but rather that they declare what they really are. As for example we say that when an angel pointing out his own nature says, I am an angel; when a man showing what he is says, I am a man: yea, if one should clothe with voice the sun, and it teaching the property of its nature should say, I hasting around the circuit of the heaven, let forth bright light to those on the earth:----one would not reasonably suppose, that it were witnessing to itself things not its, but what it really was by nature. In the same way (I deem) as to our Saviour Christ too, even though He says that He is the Light, He will say the truth, and will be found boasting not less than they in things external to Him. The many therefore living in ill-instructedness, not understanding Emmanuel, suppose that He is vain-glorious and attack Him as though one of us, and have not shuddered to say, Thy record is not true, to Him Who cannot lie, for guile was not found in His Mouth, as it is written. But it behoved Him to lead by the hand them who were astray, having fallen away exceedingly from the truth, and gone away from right reasoning, and in all forbearance to tell them that they had missed of what was becoming, unholily ascribing the love of even lying to Him Who is from above and begotten of God the Father. For true (He says) is My record, even though I hear record of Myself. For in men is sometimes seen the desire from self-love of witnessing things most excellent to themselves, even though they have them not (for prone to ill is their nature); but to Me (He says) belongs not the power of being sick of the same ills as those on the earth. For I know whence I am, Light of Light and Very God of Very God the Father, having the Nature that is beyond the reach of infirmity. For even though (He says) I became Man because of My Love for men, yet not on this account shall I be deemed bereft of God-befitting Dignity, but I remain what I am by…

The Jews then answered, "Thou bearest witness of thyself; thy witness is not true." Let us see what they hear; let us also hear, yet not as they did: they despising, we believing; they wishing to slay Christ, we desiring to live through Christ. Let this difference distinguish our ears and minds from theirs, and let us hear what the Lord answers to the Jews. "Jesus answered and said to them, Though I bear witness of myself, my witness is true; because I know whence I came and whither I go." The light shows both other things and also itself. Thou lightest a lamp, for instance, to look for thy coat, and the burning lamp affords thee light to find thy coat; dost thou light the lamp to see itself when it burns? A burning lamp is indeed capable at the same time of exposing to view other things which the darkness covered, and also of showing itself to thine eyes. So also the Lord Christ distinguished between His faithful ones and His Jewish enemies, as between light and darkness: as between those whom He illuminated with the ray of faith, and those on whose closed eyes He shed His light. So, too, the sun shines on the face of the sighted and of the blind; both alike standing and facing the sun are shone upon in the flesh, but both are not enlightened in the eyesight. The one sees, the other sees not: the sun is present to both, but one is absent from the present sun. So likewise the Wisdom of God, the Word of God, the Lord Jesus Christ, is everywhere present, because the truth is everywhere, wisdom is everywhere. One man in the east understands justice, another man in the west understands justice; is justice which the one understands a different thing from that which the other understands? In body they are far apart, and yet they have the eyes of their minds on one object. The justice which I, placed here, see, if justice it is, is the same which the just man, separated from me in the flesh by ever so many days' journey, also sees, and is united to me in the light of that justice. Therefore the light bears witness to itself; it opens the sound eyes and is its own witness, that it may be known as the light. But how about the unbelievers? Is it not present to them? It is present also to them, but they have not eyes of the heart with which to see it. Hear the sentence fetched from the Gospel itself concerning them: "And the light shineth in darkness, and the darkness…
