Cyril of Alexandria, on Isa 66:18

“But I know their works, and their thoughts: I come that I may gather them together with all nations and tongues: and they shall come and shall see my glory.”

“Christ makes, as it were, a certain recapitulation of the whole discourse, and of all prophecy through these things, and as in brief and concise terms he announces the things from the beginning to the end, and the power of the economy in the flesh. For he also remembers the calling of the nations, and the appointment of the holy apostles, and that he will be worshipped by all under heaven. For the old law gathered one and only one nation, that is, clearly, the one from Israel, and it called one tongue. But our Lord Jesus Christ did not bestow the power of the economy in the flesh on those of the blood of Israel alone, but indeed on every nation and all tongues. For He said through the lyre of the Psalmist: "Hear these things, all nations: give ear, all you who inhabit the world:" therefore I will gather all, he says: "They shall come, and shall see my glory." For they have been called through faith, and those who were once far off have become near, and they have seen his glory: how, or in what way? For they have heard through the evangelical proclamations that he is both equal in work and equal in strength to God the Father, and he has become the accomplisher of things beyond reason, so as to raise the dead from their tombs, and to give light to the blind, and in addition to these things to have done other things worthy of all account and wonder. Or in another way: they have seen his glory, having been initiated that the Word was God, and became man: for the Gentiles have not said, as the Jews did: "Why do you, being a man, make yourself God?" But rather, having recognized the mystery concerning him, they cry out those sacred words: "You are the Christ, the Son of the living God," and indeed also that which was said by the holy apostles, "Truly you are the Son of God." And a sign has also been set upon them: for as Paul says, "We were sealed with the Spirit of redemption, and Christ was formed in all our hearts through participation in the Holy Spirit."”
