"It is by your silence and cloaking that you cast suspicion upon yourself. If you believe as you declare in my presence, then speak so also in the church, in public lectures, in sermons, and in private conversations, and strengthen your brethren, and lead the erring back to the right path, and contradict the contumacious spirits; otherwise your confession is sham pure and simple, and worth nothing. Whoever really regards his doctrine, faith, and confession as true, right, and certain cannot remain in the same stall with such as teach, or adhere to, false doctrine; nor can he keep on giving friendly words to Satan and his minions. A teacher who remains silent when errors are taught, and nevertheless pretends to be a true teacher, is worse than an open fanatic and by his hypocrisy does greater damage than a heretic. Nor can he be trusted. He is a wolf and a fox, a hireling and a servant of his belly, and ready to despise and to sacrifice doctrine, Word, faith, Sacrament, churches, and schools. He is either a secret bedfellow of the enemies, or a skeptic and a weathervane, waiting to see whether Christ or the devil will prove victorious; or he has no convictions of his own whatever, and is not worthy to be called a pupil, let alone a teacher; nor does he want to offend anybody, or say a word in favor of Christ, or hurt the devil and the world.”
