To show that it is not true that the soul, when it departs from the body, comes under the dominion of evil spirits, hear what St Paul says: "He that is dead is freed from sin," (Rom. vi. 7,) that is, he no longer sins. For if while the soul dwells in the body, the devil can use no violence against it, it is clear that he cannot when the soul has departed. How is it then, say they, that men sin, if they do not suffer any violence? They sin voluntarily and intentionally, surrendering themselves without compulsion or coercion. And this all those prove who have overcome the evil one's devices. Thus [Satan] was unable to persuade Job to utter any blasphemous word, though he tried a thousand plans. Hence it is manifest that it is in our power either to be influenced or not to be influenced by his counsels; and that we are under no necessity nor tyranny from him. And not only from that which has just been said, but from the parable, it is quite certain that souls when they leave the body do not still linger here, but are forthwith led away. And hear how it is shown: "It came to pass," it is said, "that he died, and was carried away by the angels." Not the souls of the just only, but also those of sinners are led away. This also is clear from the case of another rich man. For when his land brought forth abundantly, he said within himself, "What shall I do? I will pull down my barns and build greater," (Luke xii. 18.) Than this state of mind nothing could be more wretched. He did in truth pull down his barns; for secure storehouses are not built with walls of stone; they are "the mouths of the poor." But this man neglecting these, was busy about stone walls. What, however, did God say to him? "Thou fool, this night shall they require thy soul of thee." Mark also: in one passage it is said that the soul is carried away by angels; in the other, that "they require it;" and in the latter case they lead it away as a prisoner; in the former, they guard and conduct it as a crowned victor. And like as in the arena a combatant, having received many wounds, is drenched with blood; his head being then encircled with a crown, those who stand ready by the spot take him up, and with great applause and praise they bear him home amid shouting and admiration. In this way the angels on that occasion led Lazarus also away. But in the other instance dreadful powers, probably sent for that purpose, required the soul. For it is not of its own accord that the soul departs this life; indeed, it is not able. For if when we travel from one city to another we need guides, much more does the soul stand in want of those who can conduct it, when it is separated from the flesh, and is entering upon the future state of existence. For this reason it often rises up and again sinks down into the depth below; it fears and shivers as it is about to put off the flesh. The consciousness of sin ever pierces us, and chiefly at that hour when we are about to be led hence to the account there to be rendered, and to the awful tribunal. Then, if a man has robbed, if he has been covetous, if he has been haughty, if he has unjustly been any one's enemy, if he has committed any other sin whatsoever, all the load of guilt is brought fresh to light, and being placed before the eye causes mental compunction. And as those who live in prison are always in sorrow and pain, and especially on that day when they are to be led forth, and brought to the place where they are to be tried, and placed at the bar, and hear the voice of the judge within; as they then are full of fear, and seem no better than dead men, so the soul, though it is much pained at the very moment of the sinful act, is much more afflicted when about to be hurried away.
