13.21.30   Now then let Thy ministers work upon the earth, -not as upon the waters of infidelity, by preaching and speaking by miracles, and Sacraments, and mystic words; wherein ignorance, the mother of admiration, might be intent upon them, out of a reverence towards those secret signs. For such is the entrance unto the Faith for the sons of Adam forgetful of Thee, while they hide themselves from Thy face, and become a darksome deep. But - let Thy ministers work now as on the dry land, separated from the whirlpools of the great deep: and let them be a pattern unto the Faithful, by living before them, and stirring them up to imitation. For thus do men hear, so as not to hear only, but to do also. Seek the Lord, and your soul shall live, that the earth may bring forth the living soul. Be not conformed to the world. Contain yourselves from it: the soul lives by avoiding what it dies by affecting. Contain yourselves from the ungoverned wildness of pride, the sluggish voluptuousness of luxury, and the false name of knowledge: that so the wild beasts may be tamed, the cattle broken to the yoke, the serpents, harmless. For these be the motions of our mind under an allegory; that is to say, the haughtiness of pride, the delight of lust, and the poison of curiosity, are the motions of a dead soul; for the soul dies not so as to lose all motion; because it dies by forsaking the fountain of life, and so is taken up by this transitory world, and is conformed unto it.
