1 Corinthians 10:18

21. This, then, being the state of the case, the holy apostle desiring to elevate in some degree, and to raise our understanding above the earth, says in a certain place, “Behold Israel after the flesh;” by which he certainly means that there is another Israel which is not according to the flesh, but accord­ing to the Spirit. And again in another passage, “For they are not all Israelites who are of Israel.”

21. Such, then, being the state of the case, the apostle, elevating our power of discernment (above the letter), says some­where, “Behold Israel after the flesh,” as if there were an Israel “according to the Spirit.” And in another place he says, “For they who are the children of the flesh are not the children of God;” nor are “they all Israel who are of Israel;” nor is “he a Jew who is one outwardly, nor is that ‘circumcision’ which is outward in the flesh: but he is a Jew who is one ‘inwardly;’ and circumcision is that of the heart, in the spirit, and not in the let­ter.” For if the judgment respecting the “Jew inwardly” be adopted, we must understand that, as there is a “bodily” race of Jews, so also is there a race of “Jews inwardly,” the soul having acquired this nobility for certain mysterious reasons. …

48. Now the species is not always overstepped, for things are often said of such a kind as evidently apply to it also, or perhaps even to it exclusively. But when Scripture, having up to a certain point been speaking about the species, makes a transition at that point from the species to the genus, the reader must then be carefully on his guard against seeking in the species what he can find much better and more surely in the genus. Take, for example, what the prophet Ezekiel says: “When the house of Israel dwelt in their own land, they defiled it by their own way, and by their doings: their way was before me as the uncleanness of a removed woman. …

39. “Give ye glory to God, above Israel is the magnificence of Him” ( ver. 34 ). Of whom saith the Apostle, “Upon the Israel of God.” For “not all that are out of Israel, are Israelites:” for there is also an Israel after the flesh. Whence he saith, “See ye Israel after the flesh.” “For not they that are sons of the flesh, are sons of God, but sons of promise are counted for a seed.” Therefore at that time when without any intermixture of evil men His people shall be, like a heap purged by the fan, like Israel in whom guile is not, then most pre-eminent “above Israel” shall be “the magnificence” of “Him: and the virtue of Him in the clouds.” For not alone He shall come to judgment, but with the elders of His people: to whom He hath promised that they shall sit upon thrones to judge, who even shall judge angels. These be the clouds.

Let us then become worthy of His spotless hands. Let us invite Him to strike even upon our heart. For He rather needeth not any inviting. Only make it worthy of that touch, and He will be foremost in running unto thee. For if in consideration of their attainments not yet reached, He runneth to them (for when Paul was not yet so advanced He yet framed that praise for him) when He seeth one fully furnished, what is there that He will not do? But if Christ shall sound forth and the Spirit shall indeed light upon us, and we shall be better than the heaven, having not the sun and the moon fixed in our body, but the Lord of both sun and moon and angels dwelling in us and walking in us. And this I say, not that we may raise the dead, or cleanse the lepers, but that we may show forth what is a greater miracle than all these, charity. …
