De Principiis

¹⁴ But let us take from the Gospels also the similitudes of those things which we have mentioned, in which is described a certain rock, having on it a little superficial earth, on which, when a seed falls, it is said quickly to spring up; but when sprung up, it withers as the sun ascends in the heavens, and dies away, because it did not cast its root deeply into the ground. Now this rock undoubtedly represents the human soul, hardened on account of its own negligence, and converted into stone because of its wickedness. For God gave no one a stony heart by a creative act; but each individual's heart is said to become stony through his own wickedness and disobedience. As, therefore, if one were to blame a husbandman for not casting his seed more quickly upon rocky ground, because seed cast upon other rocky soil was seen to spring up speedily, the husbandman would certainly say in reply: “I sow this soil more slowly, for this reason, that it may retain the seed which it has received; for it suits this ground to be sown somewhat slowly, lest perhaps the crop, having sprouted too rapidly, and coming forth from the mere surface of a shallow soil, should be unable to withstand the rays of the sun.” Would not he who formerly found fault acquiesce in the reasons and superior knowledge of the husbandman, and approve as done on rational grounds what formerly appeared to him as founded on no reason? And in the same way, God, the thoroughly skilled husbandman of all His creation, undoubtedly conceals and delays to another time those things which we think ought to have obtained health sooner, in order that not the outside of things, rather than the inside, may be cured. But if any one now were to object to us that certain seeds do even fall upon rocky ground, i.e., on a hard and stony heart, we should answer that even this does not happen without the arrangement of Divine Providence; inasmuch as, but for this, it would not be known what condemnation was incurred by rashness in hearing and indifference in investigation, nor, certainly, what benefit was derived from being trained in an orderly manner. And hence it happens that the soul comes to know its defects, and to cast the blame upon itself, and, consistently with this, to reserve and submit itself to training, i.e., in order that it may see that its faults must first be removed, and that then it must come to receive the instruction of wisdom. As, therefore, souls are innumerable, so also are their manners, and purposes, and movements, and appetencies, and incitements different, the variety of which can by no means be grasped by the human mind; and therefore to God alone must be left the art, and the knowledge, and the power of an arrangement of this kind, as He alone can know both the remedies for each individual soul, and measure out the time of its cure. It is He alone then who, as we said, recognises the ways of individual men, and determines by what way He ought to lead Pharaoh, that through him His name might be named in all the earth, having previously chastised him by many blows, and finally drowning him in the sea. By this drowning, however, it is not to be supposed that God's providence as regards Pharaoh was terminated; for we must not imagine, because he was drowned, that therefore he had immediately completely perished: “for in the hand of God are both we and our words; all wisdom, also, and knowledge of workmanship,” as Scripture declares. But these points we have discussed according to our ability, treating of that chapter of Scripture in which it is said that God hardened the heart of Pharaoh, and agreeably to the statement, “He has mercy on whom He will have mercy, and whom He will He hardens.”

15. Let us now look at those passages of Ezekiel where he says, I will take away from them their stony heart, and I will put in them a heart of flesh, that they may walk in My statutes, and keep Mine ordinances. For if God, when He pleases, takes away a heart of stone and bestows a heart of flesh, that His ordinances may be observed and His commandments may be obeyed, it will then appear that it is not in our power to put away wickedness. For the taking away of a stony heart seems to be nothing else than the removal of the wickedness by which one is hardened, from whomsoever God pleases to remove it. Nor is the bestowal of a heart of flesh, that the precepts of God may be observed and His commandments obeyed, any other thing than a man becoming obedient, and no longer resisting the truth, but performing works of virtue. If, then, God promises to do this, and if, before He takes away the stony heart, we are unable to remove it from ourselves, it follows that it is not in our power, but in God's only, to cast away wickedness. And again, if it is not our doing to form within us a heart of flesh, but the work of God alone, it will not be in our power to live virtuously, but it will in everything appear to be a work of divine grace. Such are the assertions of those who wish to prove from the authority of Holy Scripture that nothing lies in our own power. Now to these we answer, that these passages are not to be so understood, but in the following manner. Take the case of one who was ignorant and untaught, and who, feeling the disgrace of his ignorance, should, driven either by an exhortation from some person, or incited by a desire to emulate other wise men, hand himself over to one by whom he is assured that he will be carefully trained and competently instructed. If he, then, who had formerly hardened himself in ignorance, yield himself, as we have said, with full purpose of mind to a master, and promise to obey him in all things, the master, on seeing clearly the resolute nature of his determination, will appropriately promise to take away all ignorance, and to implant knowledge within his mind; not that he undertakes to do this if the disciple refuse or resist his efforts, but only on his offering and binding himself to obedience in all things. So also the Word of God promises to those who draw near to Him, that He will take away their stony heart, not indeed from those who do not listen to His word, but from those who receive the precepts of His teaching; as in the Gospels we find the sick approaching the Saviour, asking to receive health, and thus at last be cured. And in order that the blind might be healed and regain their sight, their part consisted in making supplication to the Saviour, and in believing that their cure could be effected by Him; while His part, on the other hand, lay in restoring to them the power of vision. And in this way also does the Word of God promise to bestow instruction by taking away the stony heart, i.e., by the removal of wickedness, that so men may be able to walk in the divine precepts, and observe the commandments of the law.
