But for the rest, let our most beloved brethren firmly decline, and avoid the words and conversations of those whose word creeps onwards like a cancer; as the apostle says, "Evil communications corrupt good manners." And again: "A man that is an heretic, after one admonition, reject: knowing that he that is such is subverted, and sinneth, being condemned of himself." And the Holy Spirit speaks by Solomon, saying, "A perverse man carrieth perdition in his mouth; and in his lips he hideth a fire." Also again, he warneth us, and says, "Hedge in thy ears with thorns, and hearken not to a wicked tongue." And again: "A wicked doer giveth heed to the tongue of the unjust; but a righteous man does not listen to lying lips." And although I know that our brotherhood there, assuredly fortified by your foresight, and besides sufficiently cautious by their own vigilance, cannot be taken nor deceived by the poisons of heretics, and that the teachings and precepts of God prevail with them only in proportion as the fear of God is in them; yet, even although needlessly, either my solicitude or my that Antichrist is near, prepares the soldiers for the battle, not only by the urgency of his speech and his words, but by the example of his faith and courage.
