Jeremias 31:34

having bestowed on us the truly great, divine, and inalienable inheritance of the Father, deifying man by heavenly teaching, putting His laws into our minds, and writing them on our hearts. What laws does He inscribe? “That all shall know God, from small to great;” and, “I will be merciful to them,” says God, “and will not remember their sins.” Let us receive the laws of life, let us comply with God’s expostulations; let us become acquainted with Him, that He may be gracious. And though God needs nothing let us render to Him the grateful recompense of a thankful heart and of piety, as a kind of house-rent for our dwelling here below.

Whatever, then, our poor ability has attempted to suggest with reference to laying hold of repentance once for all, and perpetually retaining it, does indeed bear upon all who are given up to the Lord, as being all competitors for salvation in earning the favour of God; but is chiefly urgent in the case of those young novices who are only just beginning to bedew their ears with divine discourses, and who, as whelps in yet early infancy, and with eyes not yet perfect, creep about uncertainly, and say indeed that they renounce their former deed, and assume (the profession of) repentance, but neglect to complete it. For the very end of desiring importunes them to desire somewhat of their former deeds ; just as fruits, when they are already beginning to turn into the sourness or bitterness of age, do yet still in some part flatter their own loveliness. …

In Jeremiah: “Behold, the days come, saith the Lord, and I will complete for the house of Israel, and for the house of Judah, a new testament, not according to the testament which I ordered with their fathers in that day in which I took hold of their hands to bring them out of the land of Egypt, because they remained not in my testament, and I disregarded them, saith the Lord: Because this is the testament which I will establish with the house of Israel after those days, saith the Lord: I will give them my laws, and into their minds I will write them; and I will be to them for a God, and they shall be to me for a people; and they shall not teach every man his brother, saying, Know the Lord: for all shall know me, from the least even to the greatest of them: for I will be merciful to their iniquities, and will no more be mindful of their sins.”

In the cxth Psalm: “The fear of the Lord is the beginning of wisdom.” Of the same thing in the Wisdom of Solomon: “The beginning of wisdom is to fear God.” Also in the Proverbs of the same: “Blessed is the man who reverences all things with fear.” Of the same thing in Isaiah: “And upon whom else will I look, except upon him that is lowly and peaceful, and that trembleth at my words?” Of this same thing in Genesis: “And the angel of the Lord called him from heaven, and said unto him, Abraham, Abraham: and he said, Here am I. …

32. For behold, O Lord our God, our Creator, when our affections have been restrained from the love of the world, by which we died by living ill, and began to be a “living soul” by living well; and Thy word which Thou spakest by Thy apostle is made good in us, “Be not conformed to this world;” next also follows that which Thou presently subjoinedst, saying, “But be ye transformed by the renewing of your mind,”, not now after your kind, as if following your neighbour who went before you, nor as if living after the example of a better man (for Thou hast not said, “Let man be made after his kind,” but, “Let us make man in our image, after our likeness”), that we may prove what Thy will is. …

Observe this also in that testimony which was given by the prophet on this subject in the clearest way: “Behold, the days come, saith the Lord, that I will consummate a new covenant with the house of Israel, and with the house of Judah; not according to the covenant which I made with their fathers, in the day that I took them by the hand, to bring them out of the land of Egypt. Because they continued not in my covenant, I also have rejected them, saith the Lord. But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and I will be their God, and they shall be my people. …

Accordingly, in our prophet likewise, whose testimony we are dealing with, this is added, that in God is the reward, in Him the end, in Him the perfection of happiness, in Him the sum of the blessed and eternal life. For after saying, “I will be their God, and they shall be my people,” he at once adds, “And they shall no more teach every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least even unto the greatest of them.” Now, the present is certainly the time of the New Testament, the promise of which is given by the prophet in the words which we have quoted from his prophecy. …

What then is the import of the “ All , from the least unto the greatest of them,” but all that belong spiritually to the house of Israel and to the house of Judah, that is, to the children of Isaac, to the seed of Abraham? For such is the promise, wherein it was said to him, “In Isaac shall thy seed be called; for they which are the children of the flesh are not the children of God: but the children of the promise are counted for the seed. For this is the word of promise, At this time will I come, and Sarah shall have a son. …

As then the law of works, which was written on the tables of stone, and its reward, the land of promise, which the house of the carnal Israel after their liberation from Egypt received, belonged to the old testament, so the law of faith, written on the heart, and its reward, the beatific vision which the house of the spiritual Israel, when delivered from the present world, shall perceive, belong to the new testament. Then shall come to pass what the apostle describes: “Whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away,”, even that imperfect knowledge of “the child” in which this present life is passed, and which is but “in part,” “by means of a mirror darkly.” Because of this, indeed, “prophecy” is necessary, for still to the past succeeds the future; and because of this, too, “tongues” are required, …

I beg of you, however, carefully to observe, as far as you can, what I am endeavouring to prove with so much effort. When the prophet promised a new covenant, not according to the covenant which had been formerly made with the people of Israel when liberated from Egypt, he said nothing about a change in the sacrifices or any sacred ordinances, although such change, too, was without doubt to follow, as we see in fact that it did follow, even as the same prophetic scripture testifies in many other passages; but he simply called attention to this difference, that God would impress His laws on the mind of those who belonged to this covenant, and would write them in their hearts, whence the apostle drew his conclusion, “not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart;” and that the eternal recompense of this righteousness was not …

What then could the apostle have meant to imply by, after checking the boasting of the Jews, by telling them that “not the hearers of the law are just before God, but the doers of the law shall be justified,”, immediately afterwards speaking of them “which, having not the law, do by nature the things contained in the law,” if in this description not they are to be understood who belong to the Mediator’s grace, but rather they who, while not worshipping the true God with true godliness, do yet exhibit some good works in the general course of their ungodly lives? Or did the apostle perhaps deem it probable, because he had previously said that “with God there is no respect of persons,” and had afterwards said that “God is not the God of the Jews only, but also of the Gentiles,”, that even such scanty little works of the law, as are suggested by nature, were not discovered in such as receive …

If this grace is to be called “teaching,” let it at any rate be so called in such wise that God may be believed to infuse it, along with an ineffable sweetness, more deeply and more internally, not only by their agency who plant and water from without, but likewise by His own too who ministers in secret His own increase, in such a way, that He not only exhibits truth, but likewise imparts love. For it is thus that God teaches those who have been called according to His purpose, giving them simultaneously both to know what they ought to do, and to do what they know. …
