Beatified soul, glückendes Leben

"We say that a body can be handled not only because of its resistance, but also on account of its density. But from rarity and density follow weight and lightness, heat and cold, and similar contraries, which are the principles of corruption in elementary bodies. Consequently, a body that can be handled by human touch is naturally corruptible. But if there be a body that resists touch, and yet is not disposed according to the qualities mentioned, which are the proper objects of human touch, such as a heavenly body, then such body cannot be said to be handled. But Christ's body after the Resurrection was truly made up of elements, and had tangible qualities such as the nature of a human body requires, and therefore it could naturally be handled; and if it had nothing beyond the nature of a human body, it would likewise be corruptible. But it had something else which made it incorruptible, and this was not the nature of a heavenly body, as some maintain, and into which we shall make fuller inquiry later (Suppl., Q. 82, A. 1), but it was glory flowing from a beatified soul: because, as Augustine says (Ep. ad Dioscor. cxviii): "God made the soul of such powerful nature, that from its fullest beatitude the fulness of health overflows into the body, that is, the vigor of incorruption." And therefore Gregory says (Hom. in Evang. xxvi): "Christ's body is shown to be of the same nature, but of different glory, after the Resurrection."
