" The Christian must therefore walk in the middle path, and set these two classes of men before his eyes. He may meet with hardened and obstinate ceremonialists, who, like deaf adders, refuse to listen to the truth of liberty, and cry up, enjoin, and urge on us their ceremonies, as if they could justify us without faith. Such were the Jews of old, who would not understand, that they might act well. These men we must resist, do just the contrary to what they do, and be bold to give them offence, lest by this impious notion of theirs they should deceive many along with themselves. Before the eyes of these men it is expedient to eat flesh, to break fasts, and to do in behalf of the liberty of faith things which they hold to be the greatest sins. "
― Martin Luther , On Christian Liberty
