“Vice is a sickness of the soul, and delusion is a loss of truth. Most men who are sick with the disease of vice and delusion proclaim health and are lauded by men. Unless the soul is cured from vice and is found in her natural state of health (with which she was created) so that she can be reborn by health of spirit, it is impossible for a man to desire the supernatural things of the Spirit. For so long as the soul is sick with passions, her senses have no perception of what is spiritual, and she does not even know how to desire it, saving only from the hearing of the ears and from writings.… Those who desire perfection must keep all the commandments, since the working of the commandments heals the powers of the soul. The practice of the commandments is not accomplished simply and by chance, for it is written that, "There is no remission without the shedding of blood." Our nature first received renewal through the incarnation of Christ, and it participated in His passion and death, and then, after the renewal of the shedding of blood, our nature was renewed and sanctified and became able to receive his new and perfect commandments. For if the new commandments had been given to men before the shedding of the Lord's blood, before our nature was renewed and sanctified, then it is perhaps possible that even the new commandments, like those of old, would have merely cut off vice from the soul but would have been unable completely to pluck out the very root of vice from her. But now it is not so; now there is a secret labour that accompanies the new, spiritual commandments. When the soul keeps these through the circumspection of the fear of God, they renew her, sanctify her and secretly heal all her members. For it is obvious which passion is quietly cured in the soul by each commandment. The operation of the commandments is perceived only by the healer and the healed, after the likeness of the woman who had an issue of blood.”
