"Evil life does no great harm except to itself. But evil teaching is the most pernicious thing on earth, for it leads hosts of souls to hell. Whether you are good or bad does not concern me. But I will attack your poisonous and lying teaching, which contradicts God's Word; and with God's help I will oppose it vigorously." What Luther Says, An Anthology, 3 vols., ed., Ewald Plass, St. Louis: Concordia Publishing House, 1959, I, p. 415.
