I pray not that you should take them out of the world, but that you should keep them from the evil.

Cyril of Alexandria
AD 444
What, then, is His prayer, after that He has shown that the disciples are hated by those who are fast bound by the evil things of the world? I pray not, He saith, that Thou shouldest take them from the world, but that Thou shouldest keep them from the evil one. For Christ does not wish them to be quit of human affairs, or to be rid of life in the body, when they have not yet finished the course of their apostleship, or distinguished themselves by the virtues of a godly life; but he wishes them, after they have lived their lives in the company of men in the world, and have guided the footsteps of those who are His to a state of life well pleasing to God, then at last, with the glory they have achieved, to be carried into the heavenly city, and to dwell with the company of the holy angels. We find, moreover, one of the Saints approaching the God Who loves virtue with the cry: Take me not away in the midst of my days; for pious souls cannot, without a pang, put off the garment of the flesh before they have perfected their life in holiness above their fellows. Therefore also the Law of Moses, teaching us that sinners are visited as in wrath, and by way of penalty, with premature death, often reiterates the warning to stand aloof from evil, that thou diest not before thy time. Besides, if the Saints chose to keep themselves apart from our daily life, it would infer no small loss to those who are unstable in the faith; nay, they could in nowise be guided in the way of righteousness, without the aid of those who are able to lead them therein. Paul knew this when he said, To depart and be with Christ is far better for me, yet to abide in the flesh is more needful for your sake. Christ, therefore, in His care for the salvation of the uninstructed, says that those who are in the world ought not to be left desolate without the Saints, who are men of light, and the salt of the earth; but prays rather for the safe keeping of His holy ones, and that they may be ever untouched by the malice of the evil one, shunning the assault of temptations by the power of His Omnipotent Father.
We must also remark that He calls the Word, which is His, and came forth from Him----I mean the Gospel-----the Word of God the Father, showing that He is not separate from the Father, but Consubstantial with Him. For we shall find in the writings of the Evangelists that the people of the Jews were amazed at Him, because He taught them as one having authority, and not as their Scribes. For these latter were seen to apply the teaching of the Law in every case in their discourses to them; while our Lord Jesus Christ did not at all follow slavishly the types shadowed forth in those writings, but, illumining His own Word by Divine power, exclaimed: It was said to them of old time, Thou shalt not commit adultery: but I say unto you, Thou shalt not covet; though the Law expressly says, with reference to the statutes of God, that none should add thereto or take away therefrom: but Christ took away from, and also added unto them, changing the type into truth. Therefore He cannot be reckoned among those under the Law, that is, among creatures; for on whomsoever Nature has put the brand of slavery, on him is imposed the necessity of being under the Law. Christ, then, represented His own Word as the Word of the Father. For He is the Word That is in the Father and proceedeth from Him, and That enunciates the Will of the Godhead----I mean the only true Godhead Which is in the Father, Son, and Holy Spirit.
