Translated from the Latin of Rufinus
9 Now the reason of the erroneous apprehension of all these points on the part of those whom we have mentioned above, is no other than this, that holy Scripture is not understood by them according to its spiritual, but according to its literal meaning. And therefore we shall endeavour, so far as our moderate capacity will permit, to point out to those who believe the holy Scriptures to be no human compositions, but to be written by inspiration of the Holy Spirit, and to be transmitted and entrusted to us by the will of God the Father, through His only-begotten Son Jesus Christ, what appears to us, who observe things by a right way of understanding, to be the standard and discipline delivered to the apostles by Jesus Christ, and which they handed down in succession to their posterity, the teachers of the holy Church. Now, that there are certain mystical economies indicated in holy Scripture, is admitted by all, I think, even the simplest of believers. But what these are, or of what kind they are, he who is rightly minded, and not overcome with the vice of boasting, will scrupulously acknowledge himself to be ignorant. For if anyone, e.g., were to adduce the case of the daughters of Lot, who seem, contrary to the law of God, to have had intercourse with their father, or that of the two wives of Abraham, or of the two sisters who were married to Jacob, or of the two handmaids who increased the number of his sons, what other answer could be returned than that these were certain mysteries, and forms of spiritual things, but that we are ignorant of what nature they are? Nay, even when we read of the construction of the tabernacle, we deem it certain that the written descriptions are the figures of certain hidden things; but to adapt these to their appropriate standards, and to open up and discuss every individual point, I consider to be exceedingly difficult, not to say impossible. That that description, however, is, as I have said, full of mysteries, does not escape even the common understanding. But all the narrative portion, relating either to the marriages, or to the begetting of the children, or to battles of different kinds, or to any other histories whatever, what else can they be supposed to be, save the forms and figures of hidden and sacred things? As men, however, make little effort to exercise their intellect, or imagine that they possess knowledge before they really learn, the consequence is that they never begin to have knowledge or if there be no want of a desire, at least, nor of an instructor, and if divine knowledge be sought after, as it ought to be, in a religious and holy spirit, and in the hope that many points will be opened up by the revelation of God— since to human sense they are exceedingly difficult and obscure— then, perhaps, he who seeks in such a manner will find what it is lawful to discover.
10. But lest this difficulty perhaps should be supposed to exist only in the language of the prophets, seeing the prophetic style is allowed by all to abound in figures and enigmas, what do we find when we come to the Gospels? Is there not hidden there also an inner, namely a divine sense, which is revealed by that grace alone which he had received who said, “But we have the mind of Christ, that we might know the things freely given to us by God. Which things also we speak, not in the words which man's wisdom teaches, but which the Spirit teaches?” And if one now were to read the revelations which were made to John, how amazed would he not be that there should be contained within them so great an amount of hidden, ineffable mysteries, in which it is clearly understood, even by those who cannot comprehend what is concealed, that something certainly is concealed. And yet are not the Epistles of the Apostles, which seem to some to be plainer, filled with meanings so profound, that by means of them, as by some small receptacle, the clearness of incalculable light appears to be poured into those who are capable of understanding the meaning of divine wisdom? And therefore, because this is the case, and because there are many who go wrong in this life, I do not consider that it is easy to pronounce, without danger, that anyone knows or understands those things, which, in order to be opened up, need the key of knowledge; which key, the Saviour declared, lay with those who were skilled in the law. And here, although it is a digression, I think we should inquire of those who assert that before the advent of the Saviour there was no truth among those who were engaged in the study of the law, how it could be said by our Lord Jesus Christ that the keys of knowledge were with them, who had the books of the prophets and of the law in their hands. For thus did He speak: “Woe unto you, you teachers of the law, who have taken away the key of knowledge: you entered not in yourselves, and you hindered those who wished to enter in.”
11. But, as we had begun to observe, the way which seems to us the correct one for the understanding of the Scriptures, and for the investigation of their meaning, we consider to be of the following kind: for we are instructed by Scripture itself in regard to the ideas which we ought to form of it. In the Proverbs of Solomon we find some such rule as the following laid down, respecting the consideration of holy Scripture: “And do,” he says, “describe these things to yourself in a threefold manner, in counsel and knowledge, and that you may answer the words of truth to those who have proposed them to you.” Each one, then, ought to describe in his own mind, in a threefold manner, the understanding of the divine letters—that is, in order that all the more simple individuals may be edified, so to speak, by the very body of Scripture; for such we term that common and historical sense: while, if some have commenced to make considerable progress, and are able to see something more (than that), they may be edified by the very soul of Scripture. Those, again, who are perfect, and who resemble those of whom the apostle says, “We speak wisdom among them that are perfect, but not the wisdom of this world, nor of the princes of this world, who will be brought to nought; but we speak the wisdom of God, hidden in a mystery, which God has decreed before the ages unto our glory;” — all such as these may be edified by the spiritual law itself (which has a shadow of good things to come), as if by the Spirit. For as man is said to consist of body, and soul, and spirit, so also does sacred Scripture, which has been granted by the divine bounty for the salvation of man; which we see pointed out, moreover, in the little book of The Shepherd, which seems to be despised by some, where Hermas is commanded to write two little books, and afterwards to announce to the presbyters of the Church what he learned from the Spirit. For these are the words that are written: “And you will write,” he says, “two books; and you will give the one to Clement, and the other to Grapte. And let Grapte admonish the widows and orphans, and let Clement send through all the cities which are abroad, while you will announce to the presbyters of the Church.” Grapte, accordingly, who is commanded to admonish the orphans and widows, is the pure understanding of the letter itself; by which those youthful minds are admonished, who have not yet deserved to have God as their Father, and are on that account styled orphans. They, again, are the widows, who have withdrawn themselves from the unjust man, to whom they had been united contrary to law; but who have remained widows, because they have not yet advanced to the stage of being joined to a heavenly Bridegroom. Clement, moreover, is ordered to send into those cities which are abroad what is written to those individuals who already are withdrawing from the letter—as if the meaning were to those souls who, being built up by this means, have begun to rise above the cares of the body and the desires of the flesh; while he himself, who had learned from the Holy Spirit, is commanded to announce, not by letter nor by book, but by the living voice, to the presbyters of the Church of Christ, i.e., to those who possess a mature faculty of wisdom, capable of receiving spiritual teaching.
