John 17:15

Again, our Lord gives a reason why the disciples are worthy your of obtaining such favor our from the Father: I have given them your word; and the world has hated them; i.e. They are had in hatred for your sake, and on account of your word.

They had not yet experienced these sufferings which they afterwards met with; but, after His custom, He puts the future into the past tense. Then He gives the reason why the world hated them; viz. Because they are not of the world. This was conferred upon them by regeneration; for by nature they were of the world. It was given to them that they should not be of the world, even as He was not of the world; as it follows; Even as I am not of the world. He never was of the world; for even His birth of the form of a servant He received from the Holy Ghost, from Whom they were born again. But though they were no longer of the world, it was still necessary that they should be in the world: I pray not that you should take them out of the world.

As if to say, The time is now at hand, when I shall be taken out of the world; and therefore it is necessary that they should be still left in the world, in order to preach Me and You to the world. But that you should keep them from the evil; every evil, but especially the evil of schism.

He repeats the same thing again; They are not of the world, even as I am not of the world.

Above, when He said, Then whom you gave Me out of the world, He meant their nature; here He means their actions. They are not of the world; because they have nothing, in common with earth they are made citizens of heaven. Wherein He shows His love for them, thus praising them to the Father. The word as when used with respect to Him and the Father expresses likeness of nature; but between us and Christ there is immense distance Keep them from the evil, i.e. not from dangers only, but from falling away from the faith.

Sanctify them through your truth: for thus were they to be kept from the evil. But it may be asked, how it was that they were not of the world, when they were not yet sanctified in the truth? Because the sanctified have still to grow in sanctity, and this by the help of God’s grace. The heirs of the New Testament are sanctified in that truth, the shadows of which were the sanctification of the Old Testament; they are sanctified in Christ, Who said above, I am the way, the truth, and the life. It follows, your discourse is truth. The Greek is i.e. word. The Father then sanctified them in the truth, i.e. in His Word the Only-Begotten, them, i.e. the heirs of God, and joint-heirs With Christ.

Or thus: Sanctify them in your truth; i.e. Make them holy, by the gift of the Holy Spirit, and sound doctrines: for sound doctrines give knowledge of God, and sanctify the soul. And as He is speaking of doctrines, He adds, your word is truth, i.e. there is in it no lie, nor anything typical, or bodily. Again, Sanctify them in your truth, may mean, Separate them for the ministry of the word, and preaching.

As you have sent Me into the world, even so have 1 also sent them into the world. For what Christ was sent into the world, for the same end were they as said Paul, God was in Christ reconciling the world to Himself; and has given to us the word of reconciliation. As does not express perfect likeness between our Lord and His Apostles, but only as much as was possible in men. Have sent them, He says, according to His custom of putting the past for the future.

It is manifest by this, that He is still speaking of the Apostles; for the very word Apostle means in the Greek, sent. But since they are His members, in that He is the Head of the Church, He says, And for their sakes I sanctity Myself; i.e. I in Myself sanctify them, since they are Myself. And to make it more clear that this was His meaning, He adds, That they also might be sanctified through the truth, i.e. in Me; inasmuch as the Word is truth, in which the Son of man was sanctified from the time that the Word was as made flesh. For then He sanctified Himself in Himself, i.e. Himself as man, in Himself as the Word: the Word and man being one Christ. But of His members it is that He said, And for their sakes I sanctify Myself, i.e. them in Me, since in Me both they and I are. That they also might be sanctified in truth: they also, i.e. even as Myself; and in the truth, i.e. Myself.

Or thus: for their sakes I sanctify Myself, i.e. I offer Myself as a sacrifice to You; for all sacrifices, and things that are offered to God, see called holy. And whereas this sanctification was of old in figure, (a sheep being the sacrifice,) but now in truth, He adds, That they also might be sanctified through the truth: i.e. For I make them too an oblation to You, either meaning that He who was offered up was their head, or that they would be offered up too: as the Apostle says, Present your bodies a living sacrifice, holy.

To sum up all in one word, what the soul is in the body, that are Christians in the world. The soul is dispersed through all the members of the body, and Christians are scattered through all the cities of the world. The soul dwells in the body, yet is not of the body; and Christians dwell in the world, yet are not of the world. The invisible soul is guarded by the visible body, and Christians are known indeed to be in the world, but their godliness remains invisible. The flesh hates the soul, and wars against it, though itself suffering no injury, because it is prevented from enjoying pleasures; the world also hates the Christians, though in nowise injured, because they abjure pleasures. The soul loves the flesh that hates it, and [loves also] the members; Christians likewise love those that hate them. …

22. Wherefore, having mastered this rule for interpreting the Scriptures concerning the Son of God, that we are to distinguish in them what relates to the form of God, in which He is equal to the Father, and what to the form of a servant which He took, in which He is less than the Father; we shall not be disquieted by apparently contrary and mutually repugnant sayings of the sacred books. For both the Son and the Holy Spirit, according to the form of God, are equal to the Father, because neither of them is a creature, as we have already shown: but according to the form of a servant He is less than the Father, because He Himself has said, “My Father is greater than I;” and He is less than Himself, because it is said of Him, He emptied Himself;” and He is less than the Holy Spirit, because He Himself says, “Whosoever speaketh a word against the Son of man, it shall be forgiven him; but who …

2. Hear then, ye Jews and Gentiles; hear, O circumcision; hear, O uncircumcision; hear, all ye kingdoms of the earth: I interfere not with your government in this world, “My kingdom is not of this world.” Cherish ye not the utterly vain terror that threw Herod the elder into consternation when the birth of Christ was announced, and led him to the murder of so many infants in the hope of including Christ in the fatal number, made more cruel by his fear than by his anger: “My kingdom,” He said, “is not of this world.” What would you more? Come to the kingdom that is not of this world; come, believing, and fall not into the madness of anger through fear. He says, indeed, prophetically of God the Father, “Yet have I been appointed king by Him upon His holy hill of Zion;” but that hill of Zion is not of this world. …

Another class of heretics seize upon these words of Paul, and pervert his testimony to an accusation of the present life. Lo, say they, he has called this present world evil, and pray tell me what does “world” [age] αἴων mean but time measured by days and seasons? Is then the distinction of days and the course of the sun evil? no one would assert this even if he be carried away to the extreme of unreasonableness. “But” they say, “it is not the ‘time,’ but the present ‘life,’ which he hath called evil.” Now the words themselves do not in fact say this; but the heretics do not rest in the words, and frame their charge from them, but propose to themselves a new mode of interpretation. At least therefore they must allow us to produce our interpretation, and the rather in that it is both pious and rational. …

Ver. 15 . “I pray not that Thou shouldest take them out of the world, but that Thou shouldest keep them from the evil.” Again He simplifieth His language; again He rendereth it more clear; which is the act of one showing, by making entreaty for them with exactness, nothing else but this, that He hath a very tender care for them. Yet He Himself had told them, that the Father would do all things whatsoever they should ask. How then doth He here pray for them? As I said, for no other purpose than to show His love.
