Translated from the Greek
20 Since, therefore, as will be clear to those who read, the connection taken literally is impossible, while the sense preferred is not impossible, but even the true one, it must be our object to grasp the whole meaning, which connects the account of what is literally impossible in an intelligible manner with what is not only not impossible, but also historically true, and which is allegorically understood, in respect of its not having literally occurred. For, with respect to holy Scripture, our opinion is that the whole of it has a “spiritual,” but not the whole a “bodily” meaning, because the bodily meaning is in many places proved to be impossible. And therefore great attention must be bestowed by the cautious reader on the divine books, as being divine writings; the manner of understanding which appears to us to be as follows:— The Scriptures relate that God chose a certain nation upon the earth, which they call by several names. For the whole of this nation is termed Israel, and also Jacob. And when it was divided in the times of Jeroboam the son of Nebat, the ten tribes related as being subject to him were called Israel; and the remaining two, along with the tribe of Levi, being ruled over by the descendants of David, were named Judah. And the whole of the territory which the people of this nation inhabited, being given them by God, receives the name of Judah, the metropolis of which is Jerusalem,— a metropolis, namely, of numerous cities, the names of which lie scattered about in many other passages (of Scripture), but are enumerated together in the book of Joshua the son of Nun.
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. Moreover, there are many prophecies which predict regarding Israel and Judah what is about to befall them. And do not such promises as are written concerning them, in respect of their being mean in expression, and manifesting no elevation (of thought), nor anything worthy of the promise of God, need a mystical interpretation? And if the “spiritual” promises are announced by visible signs, then they to whom the promises are made are not “corporeal.” And not to linger over the point of the Jew who is a Jew “inwardly,” nor over that of the Israelite according to the “inner man”— these statements being sufficient for those who are not devoid of understanding— we return to our subject, and say that Jacob is the father of the twelve patriarchs, and they of the rulers of the people; and these, again, of the other Israelites. Do not, then, the “corporeal” Israelites refer their descent to the rulers of the people, and the rulers of the people to the patriarchs, and the patriarchs to Jacob, and those still higher up; while are not the “spiritual” Israelites, of whom the “corporeal” Israelites were the type, sprung from the families, and the families from the tribes, and the tribes from some one individual whose descent is not of a “corporeal” but of a better kind—he, too, being born of Isaac, and he of Abraham—all going back to Adam, whom the apostle declares to be Christ? For every beginning of those families which have relation to God as to the Father of all, took its commencement lower down with Christ, who is next to the God and Father of all, being thus the Father of every soul, as Adam is the father of all men. And if Eve also is intended by the apostle to refer to the Church, it is not surprising that Cain, who was born of Eve, and all after him, whose descent goes back to Eve, should be types of the Church, inasmuch as in a pre-eminent sense they are all descended from the Church.
22. Now, if the statements made to us regarding Israel, and its tribes and its families, are calculated to impress us, when the Saviour says, “I was not sent but to the lost sheep of the house of Israel,” we do not understand the expression as the Ebionites do, who are poor in understanding (deriving their name from the poverty of their intellect— “Ebion” signifying “poor” in Hebrew), so as to suppose that the Saviour came specially to the “carnal” Israelites; for “they who are the children of the flesh are not the children of God.” Again, the apostle teaches regarding Jerusalem as follows: “The Jerusalem which is above is free, which is the mother of us all.” And in another Epistle: “But you have come unto mount Zion, and to the city of the living God, to the heavenly Jerusalem, and to an innumerable company of angels, to the general assembly and to the Church of the first-born which are written in heaven.” If, then, Israel is among the race of souls, and if there is in heaven a city of Jerusalem, it follows that the cities of Israel have for their metropolis the heavenly Jerusalem, and it consequently is the metropolis of all Judea. Whatever, therefore, is predicted of Jerusalem, and spoken of it, if we listen to the words of Paul as those of God, and of one who utters wisdom, we must understand the Scriptures as speaking of the heavenly city, and of the whole territory included within the cities of the holy land. For perhaps it is to these cities that the Saviour refers us, when to those who have gained credit by having managed their “pounds” well, He assigns the presidency over five or ten cities. If, therefore, the prophecies relating to Judea, and Jerusalem, and Israel, and Judah, and Jacob, not being understood by us in a “carnal” sense, indicate some such mysteries (as already mentioned), it will follow also that the predictions concerning Egypt and the Egyptians, Babylon and the Babylonians, Tyre and the Tyrians, Sidon and the Sidonians, or the other nations, are spoken not only of these “bodily” Egyptians, and Babylonians, and Tyrians, and Sidonians, but also of their “spiritual” (counterparts). For if there be “spiritual” Israelites, it follows that there are also “spiritual” Egyptians and Babylonians. For what is related in Ezekiel concerning Pharaoh king of Egypt does not at all apply to the case of a certain man who ruled or was said to rule over Egypt, as will be evident to those who give it careful consideration. Similarly, what is said about the ruler of Tyre cannot be understood of a certain man who ruled over Tyre. And what is said in many places, and especially in Isaiah, of Nebuchadnezzar, cannot be explained of that individual. For the man Nebuchadnezzar neither fell from heaven, nor was he the morning star, nor did he arise upon the earth in the morning. Nor would any man of understanding interpret what is said in Ezekiel about Egypt— viz., that in forty years it should be laid desolate, so that the footstep of man should not be found thereon, and that the ravages of war should be so great that the blood should run throughout the whole of it, and rise to the knees— of that Egypt which is situated beside the Ethiopians whose bodies are blackened by the sun.
