Letter 1
15 For not only the bodily wounds work death, if they are neglected, but also those of the soul; and yet we have arrived at such a pitch of folly as to take the greatest care of the former, and to overlook the latter; and although in the case of the body it naturally often happens that many wounds are incurable, yet we do not abandon hope, but even when we hear the physicians constantly declaring, that it is not possible to get rid of this suffering by medicines, we still persist in exhorting them to devise at least some slight alleviation; but in the case of souls, where there is no incurable malady; for it is not subject to the necessity of nature; here, as if the infirmities were strange we are negligent and despairing; and where the nature of the disorder might naturally plunge us into despair, we take as much pains as if there were great hope of restoration to health; but where there is no occasion to renounce hope, we desist from efforts, and become as heedless as if matters were desperate; so much more account do we take of the body than of the soul. And this is the reason why we are not able to save even the body. For he who neglects the leading element, and manifests all his zeal about inferior matters destroys and loses both; whereas he who observes the right order, and preserves and cherishes the more commanding element, even if he neglects the secondary element yet preserves it by means of saving the primary one. Which also Christ signified to us when He said, “Fear not them which kill the body, but are not able to kill the soul; but rather fear Him who is able to destroy both soul and body in Hell.”
Well, do I convince you, that one ought never to despair of the disorders of the soul as incurable? Or must I again set other arguments in motion? For even if you should despair of yourself ten thousand times, I will never despair of you, and I will never myself be guilty of that for which I reproach others; and yet it is not the same thing for a man to renounce hope of himself, as for another to renounce hope of him. For he who has this suspicion concerning another may readily obtain pardon; but he who has it of himself will not. Why so pray? Because the one has no controlling power over the zeal and repentance of the other, but over his own zeal and repentance a man has sole authority. Nevertheless even so I will not despair of you; though you should any number of times be affected in this way; for it may be, that there will be some return to virtue, and to restoration to your former manner of life. And now hear what follows: The Ninevites when they heard the prophet vehemently declaring, and plainly threatening; “yet three days and Nineveh shall be overthrown,” even then did not lose heart, but, although they had no confidence that they should be able to move the mind of God, or rather had reason to suspect the contrary from the divine message (for the utterance was not accompanied by any qualification, but was a simple declaration), even then they manifested repentance saying: “Who knows whether God will repent and be entreated, and turn from the fierceness of His wrath, and that we perish not? And God saw their works that they turned from their evil ways, and God repented of the evil which He said He would do unto them and He did it not.” Now if barbarian, and unreasoning men could perceive so much, much more ought we to do this who have been trained in the divine doctrines and have seen such a crowd of examples of this kind both in history and actual experience. “For my counsels” we read “are not as your counsels nor my ways as your ways; but far as is the Heaven from the earth, so far are my thoughts from your mind, and my counsels from your counsels.” Now if we admit to our favour household slaves when they have often offended against us, on their promising to become better, and place them again in their former portion, and sometimes even grant them greater freedom of speech than before; much more does God act thus. For if God had made us in order to punish us, you might well have despaired, and questioned the possibility of your own salvation; but if He created us for no reason than His own good will, and with a view to our enjoying everlasting blessings, and if He does and contrives everything for this end, from the first day until the present time, what is there which can ever cause you to doubt? Have we provoked Him severely, so as no other man ever did? This is just the reason why we ought specially to abstain from our present deeds and to repent for the past, and exhibit a great change. For the evils we have once perpetrated cannot provoke Him so much as our being unwilling to make any change in the future. For to sin may be a merely human failing, but to continue in the same sin ceases to be human, and becomes altogether devilish. For observe how God by the mouth of His prophet blames this more than the other. “For,” we read, “I said unto her after she had done all these deeds of fornication, return unto me, and yet she returned not.” And again: from another quarter, when wishing to show the great longing which He has for our salvation, having heard how the people promised, after many transgressions, to tread the right way He said: “Who will grant unto them to have such an heart as to fear me, and to keep my commandments all their days, that it may be well with them and with their children forever?” And Moses when reasoning with them said, “And now, O Israel, what does the Lord your God require of you, but to fear the Lord your God, and to walk in all His ways, and to love Him?” He then who is so anxious to be loved by us, and does everything for this end, and did not spare even His only begotten Son on account of His love towards us, and who counts it a desirable thing if at any time we become reconciled to Himself, how shall He not welcome and love us when we repent? Hear at least what He says by the mouth of the prophet: “Declare first your iniquities that you may be justified.” Now this He demands from us in order to intensify our love towards Him. For when one who loves, after enduring many insults at the hands of those who are beloved, even then does not extinguish his fondness for them, the only reason why he takes pains to make those insults public, is that by displaying the strength of his affection he may induce them to feel a larger and warmer love. Now if the confession of sins brings so much consolation, much more does the endeavour to wash them away by means of our deeds. For if this was not the case, but those who had once swerved from the straight path were forbidden to return to it again, perhaps no one, except a few persons whose numbers would be easily reckoned, would ever enter the kingdom of Heaven; but as it is we shall find the most distinguished among those who have fallen. For those who have exhibited much vehemence in evil things, will also in turn exhibit the same in good things, being conscious what great debts they have incurred; which Christ also declared when He spoke to Simon concerning the woman: “For do you see,” says He, “this woman? I entered into your house, you gave me no water for my feet; but she has washed my feet with her tears, and wiped them with the hairs of her head. You gave me no kiss, but she since the time I came in has not ceased to kiss my feet. Mine head with oil thou did not anoint; but she has anointed my feet with ointment. Wherefore I say unto you: her sins which are many are forgiven; for she loved much; but to whom little is forgiven, the same loves little. And He said unto her, your sins are forgiven.”
