We also believe, teach, and confess that in a time when confession is necessary, as when the enemies of God's Word want to suppress the pure teaching of the holy gospel, the entire community of God, indeed, every Christian, especially servants of the Word as leaders of the community of God, are obligated according to God's Word to confess true teaching and everything that pertains to the whole of religion freely and publicly. They are to do so not only with words but also in actions and deeds. In such a time they shall not yield to the opponents even in indifferent matters, nor shall they permit the imposition of such adiaphora by opponents who use violence or chicanery in such a way that undermines true worship of God or that introduces or confirms idolatry.
