And we believe and are sure that you are that Christ, the Son of the living God.
All Commentaries on John 6:69 Go To John 6
Cyril of Alexandria
AD 444
Marvellous is the faith of the holy Apostles, fervent their manner of confession, most loveable and pre-eminent their understanding. For not like certain of the more ignorant, or like them who used to call the Word of the Saviour hard, did they rightly go back and fall, nor of lightness readily caught were they called to belief, but being fully assured beforehand and persuaded of a truth that their Instructor was full of life-giving Words, the Teacher of heavenly doctrines. Exceeding stable is such faith, but that which is not so, is (as is like) easily spurned, and having no root as its assurance, is very readily worn away out of the mind of man. And verily the Saviour Himself in Parables, when He was discoursing of the sower, that which fell upon tho rock (He says) and hath no root withered away, darkly saying that the mind which is dried up and can in no wise receive the Word once cast into it, is a rock. For the wretched Jews being now in this case from their utter ignorance, were being taught by the Prophet's voice, Bend your hearts and not your garments. For as before the casting in of the seed, the custom of husbandry advises that the ground should first be cleft with the plough: so I deem ought they who approach to receive the Divine Words in some sort to open out aforehand their hearts by desires thereunto: and thus receiving it, do they render the soul travailing like fruitful soil. Therefore in full assurance of faith do the most wise disciples say that they know and are confident that He is Christ the Son of the Living God. And with great wisdom will you find their speech constructed as to this again. For they say they believe and know, joining both together. For one must both believe and understand: nor, because the more Divine things are to be received in faith, ought we therefore completely to depart from all investigation respecting them, but rather we should try to attain even so unto a moderate knowledge, as in a glass and a riddle, as Paul saith. Well again do they not say first that they know, then believe, but putting faith first, they bring in knowledge, and not before faith, as it is written, If ye will not believe, neither shall ye understand. For simple faith having been fore-laid in us, as a kind of foundation, knowledge is afterwards built up upon it by degrees, and brings us up to the measure of the mature age that is in Christ, to a perfect and spiritual man. Wherefore God also somewhere says, Behold I will lay for the foundations of Sion a stone, choice, a corner stone, precious. For Christ is to us a Beginning and foundation unto sanctification and righteousness, through faith, that is, and not otherwise: for thus He dwelleth in us.
But observe how they say throughout in the singular number, and with the article prefixed, THOU art the Christ, the Son of the Living God, removing from the many who are called in grace unto sonship, as One and Special, Him who is truly Son, in Whoso likeness WE too are sons. Again they call Him the Christ as One: but we must know that He is not called Christ on His own account, or as being so Essentially just as He is Son, yet is He One in truth and specially (for none among anointed ones is as He is) yet in respect of His likeness to us is He called Christ. For His Own Proper and specially distinct Name and Reality in truth, is SON; but that which is common with us is Christ. For since He was anointed in that He was made Man, therefore is He Christ. If then we attribute the being anointed to the need of human nature, He will be conceived of as Christ in respect of His likeness to us, and not in the same way as He is Son, nevertheless One Only by Nature and Specially, both before Flesh and with Flesh, and not two, as some suppose, who (it seems) understand not the depth of the Mystery. For not into a man hath the Word of God the Father come down, as the grace of the Spirit upon one (for example) of the holy Prophets, but Himself was made Flesh, as it is written, to wit Man. Indivisible therefore is He after the Union, and is not severed into two Persons, even though we conceive of the Word of God as something other than the Flesh wherein He hath dwelt. And since the whole choir of the holy Apostles confirms to us the faith herein, in that they say they know (and that peculiarly) that He is the Christ the Son of God, we shall not, if we deem aright, admit those who shrink not of their folly from making innovations on these things.
