"Every man must do two things alone; he must do his own believing and his own dying."

"You must say my sins are not mine; they are not in me at all; they are the sins of another; they are Christ's and none of my business."

"He who would be a Christian must be a Jew."

"He who lets himself be led by reason will never escape sin."

"You are not only responsible for what you say, but also for what you do not say."
