Let not your heart be troubled: you believe in God, believe also in me.
All Commentaries on John 14:1 Go To John 14
Cyril of Alexandria
AD 444
Ye believe in God, believe also in Me.
He is making an able soldier out of one who but now was a coward, and while the disciples were smarting with the anxieties of fear He bids them take to themselves the terrible power of faith. For thus are we safe, and not otherwise, according surely to the song of the Psalmist: The Lord is my illumination and my saviour; whom shall I fear? The Lord is the shield of my life; of tvhom shall I be afraid? For if the all-powerful God fights for us and shields us, who could ever have power to harm us? And who will by any chance advance to such a height of power as to keep the elect in subjection to him, and to force them to submit to the evil designs of his perverse imagination? Or who could take by his spear and lead captive those that wear the panoply of God? Faith therefore is a weapon whose blade is stout and broad, that drives away all cowardice that may spring from expectation of coming suffering, and that renders the darts of evil-doers utterly void of effect and utterly profitless of success in their temptations. And this being the nature of faith, we must further notice another point: Christ bade them believe not in God alone, but also on Himself, not implying thereby that He is at all different from the One Who is in His nature God, I mean as regards identity of essence; but that to believe in God and to suppose that the province of faith must be wholly bound up in this one phrase, is rather a peculiar characteristic of the Jewish imagination, whereas the inclusion of the name of the Son within the compass of faith in God indicates the acceptance of an injunction of evangelic preaching. For those at least who are rightly minded must believe in God the Father, and not merely in the Son, but also in the fact of His Incarnation, and in the Holy Ghost. For the Persons of the Holy and Consubstantial Trinity are distinguished both by difference of names and by the peculiar qualities and special offices of each: for the Father is Father and not Son, the Son again is Son and not Father, and the Holy Ghost is the Spirit peculiar to the Godhead. And yet the Trinity is summed up into a common Unity of Essence, so that our Creed gives us not three Gods, but one God. Still, I maintain that we must preserve accurately the definitions of our faith, not content with saying "We believe in God," but fully explaining our confession, and attaching to each Person the same measure of glory. For in our minds there should be no difference as to the intensity of our faith: our faith in the Father is not to be greater than our faith in the Son, or even than our faith in the Holy Ghost. But one and the same is the extent and the manner of our confession, uttered in regard to each of the three Persons with the same measure of faith; in such a way that herein again the Holy Trinity may appear in Unity of nature, so that the glory that encircles It may be seen in unchallenged perfection, and our souls may display our faith in the Father and in the Son, even in His Incarnation, and in the Holy Ghost. And I believe no man, if he were wise, would make any distinction between the Word of God and the Temple formed from the virgin, at least as regards the question of sonship; for there is One Lord, Jesus Christ, according to the saying of Paul. But let him who would sever into two sons Him Who is One and One alone, know surely that he is denying the faith. The inspired Paul, for instance, in working out very excellently and accurately the doctrine on this point, would have us confess our belief not simply in Christ as the Only-begotten, but also in Him as made like unto us, that is, made man, and as having both died and risen again from the dead. For what does he say? The word is nigh thee, in thy mouth, and in thy heart: that is, the word of faith, which we preach: that if thou shalt say with thy mouth, Jesus is Lord, and shalt believe in thy heart that God raised Him from the dead, thou shalt be saved: for with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Now if we believe on the Son as having risen again, who was He that died so that He might rise again? But it is evident that He is reckoned to have died according to the flesh. For His own body was imprisoned in the bonds of death, and restored to life again: for it was a body that shared in our natural life, though containing in itself in full perfection that peculiar indwelling power so mysteriously united to it, namely an energy capable of bestowing life. Whensoever therefore any one shall sever these two natures, and in separating the flesh from Him Who corporeally dwelt therein shall dare to speak of two sons, let him know that he is believing on the flesh alone. For the Divine Scriptures teach us to believe on Him Who was crucified and died and rose again from the dead, as being no other than the Word of God Himself; not so much in regard to identity of essence, for the body of Christ is body and not Word, though it be the body of the Word; but rather in respect of veritable sonship. And if any one were to think that herein we are not speaking with all possible accuracy, he would have to come forward and show us the Word Who is from God dead as regards His Divine nature, a thing which it is impossible or rather impious even to conceive.
