Gregory of Nyssa · Comentário Patrístico (catena)
João 17:10
For if the Son were not of the same nature as the Father, how could he have had in himself that which was different? Or how could he have shown in himself what was dissimilar if the foreign and alien nature did not receive the stamp of what was of a different kind from itself? But [Eunomius] says, "Neither does he have a divider of his glory." Here he speaks truly even though he does not know what he is saying. For the Son does not divide the glory with the Father but has the glory of the Father in its entirety, even as the Father has all the glory of the Son. For this is what he said to the Father, "All mine are yours and yours are mine." Notice how Christ also says that he will appear on the judgment day "in the glory of the Father," when he will render to every one according to his works. And by this phrase he shows the unity of nature that subsists between them. For as "there is one glory of the sun and another glory of the moon," because of the difference between the natures of those luminaries (since if both had the same glory we would think there was any difference in their nature), so he who foretold of himself that he would appear in the glory of the Father indicated by the identity of glory their community of nature. — AGAINST EUNOMIUS 2.6
João 17:17
The Father, the Son and the Holy Spirit alike give sanctification, life, light, comfort, and any other similar graces. And let no one attribute the power of sanctification in a special sense to the Spirit when he hears the Savior in the Gospel saying to the Father concerning his disciples, "Father, sanctify them in your name." So too all the other gifts are produced in those who are worthy alike by the Father, the Son and the Holy Spirit: every grace and power, guidance, life, comfort, the change to immortality, the passage to liberty, and every other boon that exists, which descends to us. — ON THE HOLY TRINITY
João 17:22
In giving "all power" to his disciples by his blessing, in his prayer here to the Father he grants many other favors to those who are holy. And he adds this, which is the crown of all blessings, that in all the diversity of life's decisions they should never be divided greatly in their choice of the good. And so he prays that all "may be one," united in a single good so that linked "in the bond of peace," as the apostle says, through "the unity of the [Holy] Spirit," all might become "one body and one spirit," through the "one hope" to which they have all been called.But it would be better here if we would quote the actual words of the Gospel. "That they all may be one," he says, "as you, Father, are in me, and I in you; that they also may be one in us." Now the bond of this unity is glory, and no one who would consider seriously the Lord's words would deny that this glory is the Holy Spirit. For he says, "The glory that you have given me, I have given to them." He gave his disciples this glory when he said to them, "Receive the Holy Spirit." And he himself received this glory when he put on human nature, though he had indeed always possessed it since before the beginning of the world. And now that his human nature has been glorified by the Spirit, this participation in the glory of the Spirit is communicated to all who are united with him, beginning with his disciples. — HOMILIES ON THE SONG OF SONGS 15
