It is better for you to free yourself from the shackle of sin than to free slaves from their slavery. It is better for you to make peace with your soul, causing concord to reign over the trinity within you (I mean, the body, the soul, and the spirit), than by your teaching to bring peace among men at variance....It is more profitable for you to attend to raising up unto the activity of your cogitations concerning God the deadness of your soul due to the passions, than it is to resurrect the dead.
Many have accomplished mighty acts, raised the dead, toiled for the conversion of the erring, and have wrought great wonders; and by their hands they have led many to the knowledge of God. Yet after these things, these same men who quickened others, fell into vile and abominable passions and slew themselves, becoming a stumblingblock for many when their acts were made manifest. For they were still sickly in soul, but instead of caring for their souls' health, they committed themselves to the sea of this world in order to heal the souls of others, being yet in ill health; and, in the manner I have stated, they lost their souls and fell away from their hope in God.
