Catechesis: Church Practices

We also believe, teach, and confess that at a time of confession, when the enemies of God’s Word want to suppress the pure doctrine of the Holy Gospel, God’s entire church, indeed, every single Christian, but especially the ministers of the Word, as the directors of the community of God, is bound by God’s Word to confess the doctrine freely and openly… In this case, even in adiaphora, they must not yield to the adversaries or permit these adiaphora to be forced upon them by violence or cunning to the detriment of the true worship of God and sanction of idolatry.—FC SD X:10
