v. 3 — Already ye are clean, because of the word which I have spoken unto you.
Commentary on the Gospel according to John · St Cyril of Alexandria
He makes then His disciples a palpable and convincing demonstration of the art of the purifier of their souls; for already, He says, they are purged, not through a participation in anything else, but merely by the word spoken unto them, that is, the divine guidance of the Gospel. And this word proceeds from Christ. What man of sense, then, can any longer call in question that the Father has, as it were, a pruning-knife and hand, through whose instrumentality everything exists; that is, the Son, fulfilling the activity of that husbandry in us, which He attributes to the person of the Father, teaching us that all things proceed from the Father but by the instrumentality of the Son? For it is the Word of the Saviour that purgeth us, though the husbandry of our souls is attributed to God the Father. For this is His Living Word, sharp as a sword, piercing even to the dividing of soul and spirit, of both joints and marrow, and quick to discern the thoughts and intents of the heart. For, reaching into the depths of each man's inmost soul, and having every man's hidden purpose revealed before It as God, It brings Its keen edge to bear upon our vain pursuits by the working of the Spirit. For in this, I suppose, we shall deem our purification to consist. And all things that profit us in the attainment of virtue It increases and multiplies to bear the fruit which is conceived in righteousness.
CyrJn 10.3.1
When then the manner of His husbandry of our souls is shown in the excellence of its operation, the ingenious and impious attempt of our adversaries is surely brought to nought, when they say that the Son is distinct in nature from God the Father, as He is called the Vine, and the Father the Husbandman. Let us consider and reflect on the fact that He declares that His disciples are clean, not through the special and distinct working of God the Father in them, that is, apart from the Only-begotten, but because they were obedient to His Word. As then He is the Quickener of our souls by the Son, and in the Son, in the same way as He is also the Husbandman or Guardian, He may properly be thought to act not otherwise than by the Son. And if those who start the argument against us think they ought to abide by the false theory they once broached, and, as Christ said that He was the Vine, think they are therefore, as it were, perforce compelled to degrade Him into a separate and foreign nature, what is there now to hinder us too from going to the same height of shamelessness, and distorting the meaning of the illustration, and being converted against our will by a like folly, and choosing to revolt from this puerile and ridiculous conception? For if, since He is spoken of as the Vine, they think that for this reason He falls away from His natural relationship with God the Father, and is wholly different in Substance, since the vine and the husbandman are not identical in nature; why cannot we also, encountering them with an argument as ignorant and unscholarly as their own, say this----Are only the branches profited by the care of the tiller of the soil; and will the branches that depend from the stem alone reap the profit of His art, or will the nourisher or nurse too of the branches, that is, the vine, to which they cling and are fixed by nature, require some tending? I do not think this will be difficult to demonstrate. For our adversary himself will at once agree with us that if the trunk were not tended, the branches could not remain in good condition. Since then Christ has called Himself the Vine, and the trunk itself of the vine requires the fostering care of the tiller of the soil, or it will be wholly and entirely ruined, we shall draw the inference that the Son is on a level with ourselves, and requires, as we do, the Father's providence, that He may not Himself be distorted from what He is into something else, and fall away from His native dignity or the position that He holds. For the ridiculous argument of the enemies of divine truth reduces itself to this.
CyrJn 10.3.2
But let us have done with these diseased and foolish ravings, and enter upon a discussion concerning the Holy Apostles. For He says: Already ye are clean, because of the word which I have spoken unto you: just as though He were to say, the manner of your spiritual purification, which is conceived of as by the Spirit and in the Spirit, has been wrought by the Father, through My Word on you first. Behold, casting off the burden of the vain customs and corruption of this world, be ready to bring forth fruits acceptable to God: rid yourselves of the vain and profitless law of the Jews, and pay heed to it no more. My Word has purified you: for no longer do you conduct your lives by the Mosaic Law, or according to the dispensation of the writings thereof. For you will not seek sanctification in what ye eat and drink, nor in doctrines of baptisms, nor yet in sacrificial atonements; but consider that ye are established in firm faith, and make haste to appease God by every kind of good work. For in them is seen the power of spiritual bondage. Those who are destined to be pure will be, He says, even as you are. For they, just escaping from the net of the devil, and getting away from the snares of idol-worship, will be taught no longer to be governed by his decrees; but, shaking off the impurity of former customs as vain rubbish, and being thus for the future fitted to bear the fruits of the virtue that loves God, will be joined to Me in the manner of branches; and, being dependent on their love towards Me, will have their hearts enriched by the influences of the Spirit, and, imbibing the grace of My goodness, will continue stedfast to the end and be nurtured in righteousness. The Israelites, when they have been converted to faith in Me, and have been attached to Me in the manner of branches, then receiving into their mind purification through My Word, no longer devote themselves to the service of the letter; and not fixing their heart, as now, on shadows and types, bear the fruit of a true and spiritual service to God. For God is a Spirit, and they that worship Him, must worship in Spirit and truth. At the same time also He shows clearly, as in a figure, to His disciples the beauty that will belong to those who are about to be purified, and gives them the greatest encouragement to attain the still more ample excellence; showing them that their service and the training of their past teaching had not been vain ----that teaching of the Gospel, through which they were destined to benefit those who dwell in the whole world----displaying themselves as an example to those that believe on Christ. For it has been written concerning the
