XIII. The eighth passage is, That they may know You, the only true God, and Jesus Christ Whom You have sent; and There is none good save one, that is, God. The solution of this appears to me very easy. For if you attribute this only to the Father, where will you place the Very Truth? For if you conceive in this manner of the meaning of To the only wise God, or Who only has Immortality, Dwelling in the light which no man can approach unto, or of to the king of the Ages, immortal, invisible, and only wise God, then the Son has vanished under sentence of death, or of darkness, or at any rate condemned to be neither wise nor king, nor invisible, nor God at all, which sums up all these points. And how will you prevent His Goodness, which especially belongs to God alone, from perishing with the rest? I, however, think that the passage That they may know You the only true God, was said to overthrow those gods which are falsely so called, for He would not have added and Jesus Christ Whom You have sent, if The Only True God were contrasted with Him, and the sentence did not proceed upon the basis of a common Godhead. The "None is Good" meets the tempting Lawyer, who was testifying to His Goodness viewed as Man. For perfect goodness, He says, is God's alone, even if a man is called perfectly good. As for instance, A good man out of the good treasure of his heart brings forth good things. And, I will give the kingdom to one who is good above You.... Words of God, speaking to Saul about David. Or again, Do good, O Lord, unto the good... and all other like expressions concerning those of us who are praised, upon whom it is a kind of effluence from the Supreme Good, and has come to them in a secondary degree. It will be best of all if we can persuade you of this. But if not, what will you say to the suggestion on the other side, that on your hypothesis the Son has been called the only God. In what passage? Why, in this:-This is your God; no other shall be accounted of in comparison with Him, and a little further on, after this did He show Himself upon earth, and conversed with men. This addition proves clearly that the words are not used of the Father, but of the Son; for it was He Who in bodily form companied with us, and was in this lower world. Now, if we should determine to take these words as said in contrast with the Father, and not with the imaginary gods, we lose the Father by the very terms which we were pressing against the Son. And what could be more disastrous than such a victory?
XIV. Ninthly, they allege, seeing He ever lives to make intercession for us. O, how beautiful and mystical and kind. For to intercede does not imply to seek for vengeance, as is most men's way (for in that there would be something of humiliation), but it is to plead for us by reason of His Mediatorship, just as the Spirit also is said to make intercession for us. For there is One God, and One Mediator between God and Man, the Man Christ Jesus. For He still pleads even now as Man for my salvation; for He continues to wear the Body which He assumed, until He make me God by the power of His Incarnation; although He is no longer known after the flesh -I mean, the passions of the flesh, the same, except sin, as ours. Thus too, we have an Advocate, Jesus Christ, not indeed prostrating Himself for us before the Father, and falling down before Him in slavish fashion... Away with a suspicion so truly slavish and unworthy of the Spirit! For neither is it seemly for the Father to require this, nor for the Son to submit to it; nor is it just to think it of God. But by what He suffered as Man, He as the Word and the Counsellor persuades Him to be patient. I think this is the meaning of His Advocacy.
XV. Their tenth objection is the ignorance, and the statement that Of the last day and hour knows no man, not even the Son Himself, but the Father. And yet how can Wisdom be ignorant of anything-that is, Wisdom Who made the worlds, Who perfects them, Who remodels them, Who is the Limit of all things that were made, Who knows the things of God as the spirit of a man knows the things that are in him? For what can be more perfect than this knowledge? How then can you say that all things before that hour He knows accurately, and all things that are to happen about the time of the end, but of the hour itself He is ignorant? For such a thing would be like a riddle; as if one were to say that he knew accurately all that was in front of the wall, but did not know the wall itself; or that, knowing the end of the day, he did not know the beginning of the night-where knowledge of the one necessarily brings in the other. Thus everyone must see that He knows as God, and knows not as Man;-if one may separate the visible from that which is discerned by thought alone. For the absolute and unconditioned use of the Name "The Son" in this passage, without the addition of whose Son, gives us this thought, that we are to understand the ignorance in the most reverent sense, by attributing it to the Manhood, and not to the Godhead.
XVI. If then this argument is sufficient, let us stop here, and not enquire further. But if not, our second argument is as follows:-Just as we do in all other instances, so let us refer His knowledge of the greatest events, in honour of the Father, to The Cause. And I think that anyone, even if he did not read it in the way that one of our own Students did, would soon perceive that not even the Son knows the day or hour otherwise than as the Father does. For what do we conclude from this? That since the Father knows, therefore also does the Son, as it is evident that this cannot be known or comprehended by any but the First Nature. There remains for us to interpret the passage about His receiving commandment, and having kept His Commandments, and done always those things that please Him; and further concerning His being made perfect, and His exaltation, and His learning obedience by the things which He suffered; and also His High Priesthood, and His Oblation, and His Betrayal, and His prayer to Him That was able to save Him from death, and His Agony and Bloody Sweat and Prayer, and such like things; if it were not evident to every one that such words are concerned, not with That Nature Which is unchangeable and above all capacity of suffering, but with the passible Humanity. This, then, is the argument concerning these objections, so far as to be a sort of foundation and memorandum for the use of those who are better able to conduct the enquiry to a more complete working out. It may, however, be worth while, and will be consistent with what has been already said, instead of passing over without remark the actual Titles of the Son (there are many of them, and they are concerned with many of His Attributes), to set before you the meaning of each of them, and to point out the mystical meaning of the names.
