v. 56 — Abraham your father exulted to see My Day and saw and rejoiced.
Commentary on the Gospel according to John · St Cyril of Alexandria
He here calls day nought else save the time of His Advent wherein the Very Light beamed upon us and the Sun of Righteousness arose, the darkness relaxed that held us like a mist while the prince of this world yet tyrannized, darkening (so to speak) the whole world with his perversities, thrusting it down unto idolatrous error, diversely darkening the mind of each one. Therefore the Divine Psalmist too knowing as a day the thrice-longed-for time of His Advent, fore-uttered it in the Spirit, This is the Day which the Lord made, let us exult and rejoice in it. Otherwise, it is the custom of the holy Scripture to call the time for each work, day, as, For the day of the Lord of Hosts is upon every insulter and haughty one and they shall be abased, and again, What will ye do in the day of the assembly and in the day of the feast of the Lord? yea and the Psalmist says that in that day shall the thoughts of certain perish, donning again as day the time of the Divine and looked-for Tribunal, wherein will nought avail to the renowned of the world the deceit of their olden thoughts and the empty swelling of the brow at its wealth.
CyrJn 6.56.1
Your father Abraham therefore (He says) exulted to see My Day and saw and rejoiced. And how or when we shall suppose that blessed Abraham saw the Day of our Saviour Christ, i. e., the time of His Advent with flesh? Not open to view is the utterance (for one cannot take it and just speak and explain it) yet considering well what belongs hereto (as we are able) we will say that God revealed His own Mystery just as to one of the holy Prophets. Or we shall grant that he truly saw the day of the Lord's slaughter (on account whereof all things have turned out auspiciously unto us and were made prosperous), when for a type of Him he was enjoined to offer up for a sacrifice his only-begotten and first-born, Isaac: for it is like that as he was executing the priest's office at that time, the exact force of the Mystery was made clear as in a type in that which was wrought.
CyrJn 6.56.2
One may give other occasions also for this to those who are more zealous for learning. For he saw three men at the oak in Mamre, yea and received promise from God that he should be a father of many nations, which could in no other way be fulfilled, save that the Gentiles were called through the faith Christ-ward, inscribing Abraham their father and about to sit down with him in the kingdom of heaven and to co-partake with him in the munificence unto all good things of our Saviour. Blessed Abraham therefore (He says) saw and seeing rejoiced at My Day. And why Christ proceeds to say these things also, we must needs speak of.
CyrJn 6.56.3
The Jews beholding Him a Man by reason of the veil of flesh, were conceiving of nothing God-befitting about Him, but were supposing that He too is mortal like us, as being brought from not being into being, and they would not of their great ill-counsel believe that He was Eternal, as being of the Eternal Father. In order then that He might clearly shew, that He is not recent nor just-made as are we, but that He was known of their very oldest Fathers also as being Eternal, does He say these things. In the same does He (it seems) profitably reproach them, because acting ill-advisedly and foolishly minded they spurn what was a very gala to the beginner of their race. For he did but see and he rejoiced, they having Him and it being in their power to enjoy Him insult Him by their unbelief and set themselves in braggart wise against so glorious grace. Or perhaps He covertly intimates this that He is both greater and superior to Abraham seeing it was to him a festal assembly, to only know somewhat of Him: for He could not say it openly and apart from any veil, by reason of their being mighty to wrath, but He indicates it in another way.
CyrJn 6.56.4
And let no one suppose that Jesus in saying Abraham your father [died ], contradicts Himself, in that He in one place removes them from relation with Abraham, saying, If ye were Abraham's children, ye would do the works of Abraham, but now again calls them Abraham's sons: but we must know that well does He in either case direct His discourse unto the truth. For in the former, defining the quality of spiritual nobility, He depicts a relation in sameness of habits, here He allots them mere bare kindred of the flesh, that both in the former He may be true, and here not false.
CyrJn 6.56.5
57 The Jews said therefore to Him, Thou art not yet fifty years old, and hast Thou seen Abraham?
CyrJn 6.56.6
Utterly without understanding is the Jews' speech, and big with much absurdity, and one may wonder (and with much reason) at their proceeding to so great lack of understanding, as to be utterly unable to conceive as they ought. For though our Saviour Christ had devised full many turns of speech, over and over going through the same words and manifoldly indicating therein His own Eternity, they think no whit more than they see with the eyes of the body, but as though utterly distraught and the whole power of their mind deranged, they reach not forth their heart unto what beseems God, but as if He were some man like us, then barely beginning to be and be accounted among things that are, when he was born, they senselessly accuse Him of a lie, not even deeming aright of what they heard Him say. For He said that Abraham had seen His Day, they turn about to the contrary the force of His word, for (say they) Thou art not yet fifty years old and how hast Thou beheld Abraham? miserable therefore is the senseless Jew, ever comrade of much uninstructedness, and making madness his wild foster brother.
CyrJn 6.56.7
Again does Christ advance to His wonted and favourite contrivance, for He speaks at times exceeding obscurely and overshadowing His exposition with diverse veils suffers it not to be open to all. But when He sees that the hearers understand nothing at all, then having stripped His discourse of its obscurity, He sets it before them plain and clear. And this He studies to do on the present occasion. For since He found that they understood nought (albeit a long discourse had been gone through) nor yet were able to understand that He is both Eternal as being of an Eternal Father, and that He is incomparably greater than Abraham as being God, He now says openly, adding Amen in the rank of an oath for confirmation of the things said, Before Abraham was I am. And we shall in no wise think that the Only-Begotten is boasting of being before Abraham only, for He is before all time and hath His Generation most ancient, being without beginning in the Father. But since the comparison with Abraham was before Him at present, He says that He is elder than he; just as if the number 100, for instance, were to say, I am greater than 10: it would not surely be saying this, as having the next place above ten, but because it is exceeding much superior and above ten. He therefore is not rivalling Abraham's times, nor does He affirm that He is some little precedent to his times: but since He is above all time, and o'erpasseth the number of every age, He says that He is before Abraham, uttering a truth.
CyrJn 6.56.9
And exceeding rightly and well does He of Abraham put, Was, of Himself, I am, shewing that to him that was made of things which are not, will full surely follow the necessity of decaying, to Him That ever is will never befall the passing into not being.
