Origen

“ Is it befitting to say of the physician, who looks on dreadful sights and handles unsightly objects in order to cure the sufferers, that he passes from “good to evil,” or from “virtue to vice,” or from “happiness to misery?” And yet the physician, in looking on dreadful sights and handling unsightly objects, does not wholly escape the possibility of being involved in the same fate. But He who heals the wounds of our souls, through the word of God that is in Him, is Himself incapable of admitting any wickedness. ”
