That they all may be one; as you, Father, are in me, and I in you, that they also may be one in us: that the world may believe that you have sent me.

That they may be all one. By one faith, hope, charity, and concord. Learn hence how united Christians should be amongst themselves, and how far removed are they who disseminate discord and strife, from the mind of Christ.
As Thou, Father, art in Me, and I in Thee, that they also may be one in Us. For God is love, and he that abideth in love abideth in God, and God in him. 1 John 4:16. By faith then and love we are united to God and Christ, and afterwards mutually to each other as to members of Christ"s Mystical Body, the Church. The word "as" does not mean identity, as the Arians held, but merely resemblance. For the Father and the Son are one by the same numerical Essence and Godhead, we are one by having the same quality; namely, love and concord. But by this we are so united to God as to possess Him, and be in turn possessed by Him. Hear the author "De Salutaribus documentis," assigned to S. Augustine [probably Paulinus of Aquileia]: "If we are pleased at possessing anything in this world, it is good for us to keep in our minds God who created and is the Possessor of all things, and to have in Him all that we holily and happily desire. But since no one possesses God, save he that is possessed by Him, let us become the possession of God, and He will become our possession. For what greater happiness can there be in the world, than to have our Lord and our Redeemer counted as our own, and whose inheritance the Godhead deigns to be? For we enjoy every blessing from Him if we live from Him, and in Him. For what, I ask you, suffices a Prayer of Manasseh , if the Creator Himself does not suffice him? What does he seek further, whose Redeemer ought to be his sole joy, and everything to him? By love therefore we are so united to God as to be made one Spirit, that so all earthly desires in us may be swallowed up, and our whole mind be so raised up by its affections to God, as to be, in a way, deified. Just as a drop of water poured into generous wine is absorbed in it, and as iron when heated passes into heat, though the nature of the iron still remains, and as the air illumined by the sun turns into light, so that it seems to be nothinag else but the light of the sun," And S. Bernard (Sermon lxxi. on Cant.) says, "Who is He that cleaves perfectly to God, save He who, abiding in God, as beloved by Him, has in like measure drawn God into himself by loving Him in return? And thus when men cleave to each other on all sides, being bound up in their mutual and intimate love for each other, I should not hesitate to say that in this way God was in man and man in God." This union they feel and enjoy, who with Magdalen pass a contemplative life. For in that life the loving soul flows away from itself, and reduced, as it were to nothing, falls back, and is absorbed into the abyss of eternal love, and being utterly dead to itself, lives only to God, knowing nothing, and caring for nothing except Himself. For it loses itself in the boundless solitude and depth of the Godhead, but to lose itself thus, is far happier and far more for its own good, than to find itself. For stripping itself of everything human, and arraying itself in everything which is Divine, it is thus transformed and changed into God0 truly blessed is the soul, which has laid aside all its own0 truly blessed is the soul, which casting off every action which springs from itself in its power of memory, strips itself of all its imaginings, in its understanding feels and cherishes the brilliant rays of the Sun of righteousness, in its faculty of desire feels a certain glow of calm love, or the action of the Holy Spirit flowing with rivers of eternal sweetness, like some real fountain. For when it is set free and detached from all things else, and it exists in its own simplicity, and is cleansed as a bright mirror, the Lord is wont to enlighten it with the rays of His own Divine brightness. For when God Himself is acting, man is only passive. For when the powers of the soul are resting, and not engaged in their own proper actions, and set free from any outward impressions, God Himself speaks, and disposes, and impresses those powers of the soul just as He pleases, carrying on within a most glorious work. And therefore, 0 most generous, 0 most noble soul, keep thyself pure and free, rush not ahead for every variety of sensual pleasure, but restrain thy senses, dwell in thine own thoughts, turn thyself ardently to God, and immersed a thousand times daily in the abyss of the Godhead, be careful to swim up and down therein. Pant for that supernatural union of the spirit with God, fly back to God from whom thou derivest thy being, for He is the uncreated Light, and the Light also of eternity." Accordingly S. Bernard rightly exclaims (De Div. Amor, cap. iv.), "O happy, yea most happy soul, whom God vouchsafes to influence so that by unity of spirit with God it loves God only, and not its own private good, and loves itself only as in God; while God loves or approves in it only that which He ought to approve, that is to say Himself, which in truth ought alone to be loved both by the Creator and the creature. For the name and feeling of love belongs and is due to Thee alone, 0 thou beloved Lord, Thou true love." And he concludes thus with the words from S. John , "This is the will of Thy Son in us. This His prayer to Thee His Father, I will that as I and Thou art one, so they also may be one in Us. This is the end, this the consummation, this is perfection, this is peace, this is joy in the Holy Ghost, this is silence in heaven."
That the world may believe that Thou hast sent Me. Not merely through its unity and agreement in doctrine, as Euthymius supposes, but through its union with God and Christ. That Isaiah , even by this mark alone will the world believe Christ to be the Son of God, because it will behold Christians both united to God and Christ as well as by mutual love to each other. For it will see that such an union could not be effected except by Christ and God. And therefore it will be attracted by this, so as, though now unbelieving, to cast off its unbelief and to believe. The "world" is here used in a good sense, as in John iii17,2Cor. v19. Jansen less correctly considers the "world" here to mean the reprobate; in this sense, "That it will be forced by the evidence of the miracles and the holiness of My disciples to confess Me to be God. As S. James says, "the devils believe and tremble.""
