I say therefore that any man who tells us that there are seven sacraments, when the Bible only mentions two; or that any man-made ordinance is as binding on our consciences and as needful to salvation as an ordinance appointed by Christ, is telling us what he has no right to tell. We must not listen to him. He is committing not only a mistake, but a sin.
