8 “My wounds stink and are corrupt”. Now he who has wounds is not perfectly sound. Add to this, that the wounds “stink and are corrupt.” Wherefore do they “stink”? Because they are “corrupt:” now in what way this is explained in reference to human life, who does not understand? Let a man but have his soul's sense of smelling sound, he perceives how foully sins stink. The contrary to which stink of sin, is that savour of which the Apostle says, “We are the sweet savour of Christ unto God, in every place, unto them which be saved.” But whence is this, except from hope? Whence is this, but from our “calling the Sabbath to remembrance”? For it is a different thing that we mourn over in this life, from that which we anticipate in the other. That which we mourn over is stench, that which we reckon upon is fragrance. Were there not therefore such a perfume as that to invite us, we should never call the Sabbath to remembrance. But since, by the Spirit, we have such a perfume, as to say to our Betrothed, “Because of the savour of Your good ointments we will run after You;” we turn our senses away from our own unsavourinesses, and turning ourselves to Him, we gain some little breathing-time. But indeed, unless our evil deeds also did smell rank in our nostrils, we should never confess with those groans, “My wounds stink and are corrupt.” And wherefore? “from the face of my foolishness.” From the same cause that he said before, “from the face of my sins;” from that same cause he now says, “from the face of my foolishness.”
9. “I am troubled, I am bowed down even unto the end”. Wherefore was he “bowed down”? Because he had been “lifted up.” If you are “humble, you shall be exalted;” if you exalt yourself, you shall be “bowed down;” for God will be at no loss to find a weight wherewith to bow you down....Let him groan on these things; that he may receive the other; let him “call the Sabbath to remembrance,” that he may deserve to arrive at it. For that which the Jews used to celebrate was but a sign. Of what thing was it the sign? Of that which he calls to remembrance, who says, “I am troubled, and am bowed down even unto the end.” What is meant by even “unto the end”? Even to death.
“I go mourning all the day long.” “All day long,” that is, “without intermission.” By “all the day long,” he means, “all my life long.” But from what time has he known it? From the time that he began to “call the Sabbath to remembrance.” For so long as he “calls to remembrance” what he no longer possesses, would you not have him “go mourning”? “All the day long have I gone mourning.”
10. “For my soul is filled with illusions, and there is no soundness in my flesh”. Where there is the whole man, there there is soul and flesh both. The “soul is filled with illusions;” the flesh has “no soundness.” What does there remain that can give joy? Is it not meet that one should “go mourning”? “All the day long have I gone mourning.” Let mourning be our portion, until our soul be divested of its illusions; and our body be clothed with soundness. For true soundness is no other than immortality. How great however are the soul's illusions, were I even to attempt to express, when would the time suffice me? For whose soul is not subject to them? There is a brief particular that I will remind you of, to show how our soul is filled with illusions. The presence of those illusions sometimes scarcely permits us to pray. We know not how to think of material objects without images, and such as we do not wish, rush in upon the mind; and we wish to go from this one to that, and to quit that for another. And sometimes you wish to return to that which you were thinking of before, and to quit that which you are now thinking of; and a fresh one presents itself to you; you wish to call up again what you had forgotten; and it does not occur to you; and another comes instead which you would not have wished for. Where meanwhile was the one that you had forgotten? For why did it afterwards occur to you, when it had ceased to be sought after; whereas, while it was being sought for, innumerable others, which were not desired, presented themselves instead of it? I have stated a fact briefly; I have thrown out a kind of hint or suggestion to you, brethren, taking up which, you may yourselves suggest the rest to yourselves, and discover what it is to mourn over the “illusions” of our “soul.” He has received therefore the punishment of illusion; he has forfeited Truth. For just as illusion is the soul's punishment, so is Truth its reward. But when we were set in the midst of these illusions, the Truth Itself came to us, and found us overwhelmed by illusions, took upon Itself our flesh, or rather took flesh from us; that is, from the human race. He manifested himself to the eyes of the Flesh, that He might “by faith” heal those to whom He was going to reveal the Truth hereafter, that Truth might be manifested to the now healed eye. For He is Himself “the Truth,” which He promised unto us at that time, when His Flesh was to be seen by the eye, that the foundation might be laid of that Faith, of which the Truth was to be the reward. For it was not Himself that Christ showed forth on earth; but it was His Flesh that He showed. For had He showed Himself, the Jews would have seen and known Him; but had they “known Him, they would never have crucified the Lord of Glory.” But perhaps His disciples saw Him, when they said unto Him, “Show us the Father, and it suffices us;” and He, to show that it was not Himself that had been seen by them, added: “Have I been so long with you, and have ye not known Me, Philip? He that sees Me, sees the Father also.” If then they saw Christ, wherefore did they yet seek for the Father? For if it were Christ whom they saw, they would have seen the Father also. They did not therefore yet see Christ, who desired that the Father should be shown unto them. To prove that they did not yet see Him, hear that, in another place, He promised it by way of reward, saying, “He who loves Me, keeps My commandments; and whoso loves Me, shall be loved of My Father; and I will love Him and” (as if it were said to Him, “what will You give unto him, as You love him?” He says), “I will manifest Myself unto him.” If then He promises this by way of a reward unto them that love Him, it is manifest that the vision of the Truth, promised to us, is of such a nature, that, when we have seen it, we shall no longer say, “My soul is filled with illusions.”
