2 Corinthians 4:16

But though our outward man perish. Though the body be corrupted through persecutions, afflictions, hunger, thirst, cold, nakedness, scourgings, and diseases, yet the spirit within is renewed, and advances in faith, hope, charity, readiness of mind, and, like gold from the fire, comes out stronger and brighter, says Chrysostom.

This verse differs from Romans 7:22. There the outward man is concupiscence, or the man governed by concupiscence; the inward man is charity, or the man renewed by the spirit. But here the outward man is the body, the inward is the soul; or, more appositely, the outward man is the man regarded as corporeal, or in so far as through his body he is visible, tangible, passible, and susceptible of injuries from without; the inward man is the same man regarded as possessed of a soul, or in so far as through his soul he is invisible, and bravely and cheerfully bears bodily afflictions. Since man consists of two so dissimilar parts, the body without and the soul within, and since the soul itself seems to have two sides, one which animates the body, and shows itself outwardly in the body by its working and passions, and so seems in a sense outward, animal, and embodied; one self-contained, concerned only with the operations of the mind, and so seems inward and invisible, hence man, consisting of these two parts, is called outward in the first respect, and inward in the second.

Hence it is evident, against Illyricus, that original sin and concupiscence are not an evil substance formed from man by the devil, and united to man's substance as its form; for this form would be the inward man, and that so corrupt as to be incapable of renewal, opposed to what the Apostle says here.

Tertullian was wrong, says S. Thomas, in gathering from this passage that the soul is corporeal, and has its figure and members like the body, so that the inward man is but a copy of the outward. In the same way John Huart, a physician, in his Examen Ingeniorum, lately published, has maintained that the souls of the lost are tortured by fire, because, he says, they have their members or images of members, they have their senses and sensations, in the same way that Dives said that his tongue was tormented, in S. Luke 16

But this opinion is baseless. As the soul is not corporeal, it has no members strictly speaking; but what is said of its senses and sensations may be true. For the rational soul, being also sensitive, has within itself a root of sense and sensation, e.g., touch, by which it feels heat and fire, and the pain they cause. Although this sensation cannot be exercised naturally apart from the body, yet God can supernaturally produce it in a soul separated from the body; for such a soul has and retains the root of sensation within itself. This is the opinion of many subtle philosophers, and they find it easy in this way to explain how fire affects the soul. Reason, too, is in their favour; for sensation wholly consists in the soul. When, e.g., we see with the eye, or hear with the ear, or touch with the hand, the sight, or bearing, or perception of touch is not in the eye, or ear, or hand, but in the soul. It is not the body but the soul which sees by the eye, hears by the ear, and touches by the hand; why, then, cannot God, by His omnipotence, produce the same sensation in a soul separated from the body? The natural use of the organs of the body, which has been lost at death, may be supernaturally replaced, as He can and does sometimes supply the object of sensation; as, e.g., he may enable a man to see through a wall what is being done in a closed bedroom, or see what is taking place in distant countries. We read of such things in the life of Anselm and other Saints.

Day by day. As the outward, i.e., the body daily is weakened and aged by affliction, so the inward man, i.e., the mind, is daily renewed and gifted with youth through the hope of resurrection. We read of Abbot Barnabas in Sophronius (Prat. Spir. c. x.), that he drove a thorn into his foot and refused to have it taken out, and so caused his foot to fester; and when some expressed their wonder, he said. "The more the outward man suffers, the more does the inward flourish." In the same work, in chap. viii., we read of Myrogenes, a man afflicted with dropsy, saying: "Pray for me, fathers, that the inward man may not grow dropsical, for my prayer to God is that I may live a long time in this weakness." No doubt these Saints applied this general declaration of the Apostle to their own particular diseases.

So that admirable martyr, Clement of Ancyra, when tortured by Agathangelus, under the Emperor Diocletian, with every possible kind of torture, though broken in body, yet became daily stronger, so much so as to long for fresh tortures, and to pray God that his life might be prolonged for them, and obtained his request. He lived for twenty eight years, during which he was constantly tortured. At length Diocletian and the judges, amazed at his constancy, asked him how he could bear such tortures, and he answered in these words of Paul: "Though our outward man perish, yet the inward man is renewed day by day."
