The answer concerning the trampling down of shame, and the danger of one without contrition.
Moses: Just as all young men are not alike in fervour of spirit nor equally instructed in learning and good morals, so too we cannot find that all old men are equally perfect and excellent. For the true riches of old men are not to be measured by grey hairs but by their diligence in youth and the rewards of their past labours. “For,” says one, “the things that you have not gathered in your youth, how shall you find them in your old age?” “For venerable old age is not that of long time, nor counted by the number of years: but the understanding of a man is grey hairs, and a spotless life is old age.” And therefore we are not to follow in the steps or embrace the traditions and advice of every old man whose head is covered with grey hairs, and whose age is his sole claim to respect, but only of those whom we find to have distinguished themselves in youth in an approved and praiseworthy manner, and to have been trained up not on self-assurance but on the traditions of the Elders. For there are some, and unhappily they form the majority, who pass their old age in a lukewarmness which they contracted in youth, and in sloth, and so obtain authority not from the ripeness of their character but simply from the number of their years. Against whom that reproof of the Lord is specially aimed by the prophet: “Strangers have devoured his strength and he knew it not: yea, grey hairs also are spread about upon him, and he is ignorant of it.” These men, I say, are not pointed out as examples to youth from the uprightness of their lives, nor from the strictness of their profession, which would be worthy of praise and imitation, but simply from the number of their years; and so the subtle enemy uses their grey hairs to deceive the younger men, by a wrongful appeal to their authority, and endeavours in his cunning craftiness to upset and deceive by their example those who might have been urged into the way of perfection by their advice or that of others; and drags them down by means of their teaching and practice either into a baneful indifference, or into deadly despair. And as I want to give you an instance of this, I will tell you a fact which may supply us with some wholesome teaching, without giving the name of the actor, lest we might be guilty of something of the same kind as the man who published abroad the sins of the brother which had been disclosed to him. When this one, who was not the laziest of young men, had gone to an old man, whom we know very well, for the sake of the profit and health of his soul, and had candidly confessed that he was troubled by carnal appetites and the spirit of fornication, fancying that he would receive from the old man's words consolation for his efforts, and a cure for the wounds inflicted on him, the old man attacked him with the bitterest reproaches, and called him a miserable and disgraceful creature, and unworthy of the name of monk, while he could be affected by a sin and lust of this character, and instead of helping him so injured him by his reproaches that he dismissed him from his cell in a state of hopeless despair and deadly despondency. And when he, oppressed with such a sorrow, was plunged in deep thought, no longer how to cure his passion, but how to gratify his lust, the Abbot Apollos, the most skilful of the Elders, met him, and seeing by his looks and gloominess his trouble and the violence of the assault which he was secretly revolving in his heart, asked him the reason of this upset; and when he could not possibly answer the old man's gentle inquiry, the latter perceived more and more clearly that it was not without reason that he wanted to hide in silence the cause of a gloom so deep that he could not conceal it by his looks, and so began to ask him still more earnestly the reasons for his hidden grief. And by this he was forced to confess that he was on his way to a village to take a wife, and leave the monastery and return to the world, since, as the old man had told him, he could not be a monk, if he was unable to control the desires of the flesh and to cure his passion. And then the old man smoothed him down with kindly consolation, and told him that he himself was daily tried by the same pricks of desire and lust, and that therefore he ought not to give way to despair, nor be surprised at the violence of the attack of which he would get the better not so much by zealous efforts, as by the mercy and grace of the Lord; and he begged him to put off his intention just for one day, and having implored him to return to his cell, went as fast as he could to the monastery of the above mentioned old man— and when he had drawn near to him he stretched forth his hands and prayed with tears, and said “O Lord, who alone art the righteous judge and unseen Physician of secret strength and human weakness, turn the assault from the young man upon the old one, that he may learn to condescend to the weakness of sufferers, and to sympathize even in old age with the frailties of youth.” And when he had ended his prayer with tears, he sees a filthy Ethiopian standing over against his cell and aiming fiery darts at him, with which he was straightway wounded, and came out of his cell and ran about here and there like a lunatic or a drunken man, and going in and out could no longer restrain himself in it, but began to hurry off in the same direction in which the young man had gone. And when Abbot Apollos saw him like a madman driven wild by the furies, he knew that the fiery dart of the devil which he had seen, had been fixed in his heart, and had by its intolerable heat wrought in him this mental aberration and confusion of the understanding; and so he came up to him and asked “Whither are you hurrying, or what has made you forget the gravity of years and disturbed you in this childish way, and made you hurry about so rapidly”?
