Translated from the Latin of Rufinus
7 It is, however, a matter attended with considerable labour, to point out, in every instance, how and when the predictions of the prophets were fulfilled, so as to appear to confirm those who are in doubt, seeing it is possible for everyone who wishes to become more thoroughly acquainted with these things, to gather abundant proofs from the records of the truth themselves. But if the sense of the letter, which is beyond man, does not appear to present itself at once, on the first glance, to those who are less versed in divine discipline, it is not at all to be wondered at, because divine things are brought down somewhat slowly to (the comprehension of) men, and elude the view in proportion as one is either sceptical or unworthy. For although it is certain that all things which exist in this world, or take place in it, are ordered by the providence of God, and certain events indeed do appear with sufficient clearness to be under the disposal of His providential government, yet others again unfold themselves so mysteriously and incomprehensibly, that the plan of Divine Providence with regard to them is completely concealed; so that it is occasionally believed by some that particular occurrences do not belong to (the plan of) Providence, because the principle eludes their grasp, according to which the works of Divine Providence are administered with indescribable skill; which principle of administration, however, is not equally concealed from all. For even among men themselves, one individual devotes less consideration to it, another more; while by every man, He who is on earth, whoever is the inhabitant of heaven, is more acknowledged. And the nature of bodies is clear to us in one way, that of trees in another, that of animals in a third; the nature of souls, again, is concealed in a different way; and the manner in which the diverse movements of rational understandings are ordered by Providence, eludes the view of men in a greater degree, and even, in my opinion, in no small degree that of the angels also. But as the existence of divine providence is not refuted by those especially who are certain of its existence, but who do not comprehend its workings or arrangements by the powers of the human mind; so neither will the divine inspiration of holy Scripture, which extends throughout its body, be believed to be non-existent, because the weakness of our understanding is unable to trace out the hidden and secret meaning in each individual word, the treasure of divine wisdom being hid in the vulgar and unpolished vessels of words, as the apostle also points out when he says, “We have this treasure in earthen vessels,” that the virtue of the divine power may shine out the more brightly, no colouring of human eloquence being intermingled with the truth of the doctrines. For if our books induced men to believe because they were composed either by rhetorical arts or by the wisdom of philosophy, then undoubtedly our faith would be considered to be based on the art of words, and on human wisdom, and not upon the power of God; whereas it is now known to all that the word of this preaching has been so accepted by numbers throughout almost the whole world, because they understood their belief to rest not on the persuasive words of human wisdom, but on the manifestation of the Spirit and of power. On which account, being led by a heavenly, nay, by a more than heavenly power, to faith and acceptance, that we may worship the sole Creator of all things as our God, let us also do our utmost endeavour, by abandoning the language of the elements of Christ, which are but the first beginnings of wisdom, to go on to perfection, in order that that wisdom which is given to them who are perfect, may be given to us also. For such is the promise of him to whom was entrusted the preaching of this wisdom, in the words: “Howbeit we speak wisdom among them that are perfect; yet not the wisdom of this world, nor of the princes of this world, who will be brought to nought;” by which he shows that this wisdom of ours has nothing in common, so far as regards the beauty of language, with the wisdom of this world. This wisdom, then, will be inscribed more clearly and perfectly on our hearts, if it be made known to us according to the revelation of the mystery which has been hid from eternity, but now is manifest through the Scriptures of prophecy, and the advent of our Lord and Saviour Jesus Christ, to whom be glory for ever. Amen.
Many, not understanding the Scriptures in a spiritual sense, but incorrectly, have fallen into heresies.
8. These particulars, then, being briefly stated regarding the inspiration of the sacred Scriptures by the Holy Spirit, it seems necessary to explain this point also, viz., how certain persons, not reading them correctly, have given themselves over to erroneous opinions, inasmuch as the procedure to be followed, in order to attain an understanding of the holy writings, is unknown to many. The Jews, in fine, owing to the hardness of their heart, and from a desire to appear wise in their own eyes, have not believed in our Lord and Saviour, judging that those statements which were uttered respecting Him ought to be understood literally, i.e., that He ought in a sensible and visible manner to preach deliverance to the captives, and first build a city which they truly deem the city of God, and cut off at the same time the chariots of Ephraim, and the horse from Jerusalem; that He ought also to eat butter and honey, in order to choose the good before He should come to know how to bring forth evil. They think, also, that it has been predicted that the wolf— that four-footed animal— is, at the coming of Christ, to feed with the lambs, and the leopard to lie down with kids, and the calf and the bull to pasture with lions, and that they are to be led by a little child to the pasture; that the ox and the bear are to lie down together in the green fields, and that their young ones are to be fed together; that lions also will frequent stalls with the oxen, and feed on straw. And seeing that, according to history, there was no accomplishment of any of those things predicted of Him, in which they believed the signs of Christ's advent were especially to be observed, they refused to acknowledge the presence of our Lord Jesus Christ; nay, contrary to all the principles of human and divine law, i.e., contrary to the faith of prophecy, they crucified Him for assuming to Himself the name of Christ. Thereupon the heretics, reading that it is written in the law, “A fire has been kindled in Mine anger;” and that “I the Lord am a jealous (God), visiting the sins of the fathers upon the children unto the third and fourth generation;” and that “it repents Me that I anointed Saul to be king;” and, “I am the Lord, who make peace and create evil;” and again, “There is not evil in a city which the Lord has not done;” and, “Evils came down from the Lord upon the gates of Jerusalem;” and, “An evil spirit from the Lord plagued Saul;” and reading many other passages similar to these, which are found in Scripture, they did not venture to assert that these were not the Scriptures of God, but they considered them to be the words of that creator God whom the Jews worshipped, and who, they judged, ought to be regarded as just only, and not also as good; but that the Saviour had come to announce to us a more perfect God, who, they allege; is not the creator of the world—there being different and discordant opinions among them even on this very point, because, when they once depart from a belief in God the Creator, who is Lord of all, they have given themselves over to various inventions and fables, devising certain (fictions), and asserting that some things were visible, and made by one (God), and that certain other things were invisible, and were created by another, according to the vain and fanciful suggestions of their own minds. But not a few also of the more simple of those, who appear to be restrained within the faith of the Church, are of opinion that there is no greater God than the Creator, holding in this a correct and sound opinion; and yet they entertain regarding Him such views as would not be entertained regarding the most unjust and cruel of men.
