 Unless I am convinced by the testimony of the Scriptures or by clear reason (for I do not trust either in the Pope or in councils alone, since it is well known that they often erred and contradicted themselves), I am bound by the Scriptures I have quoted and my conscience is captive to the Word of God. I cannot and will not retract anything, since it is neither safe nor right to go against conscience. (1521, WA 7:838/LW 32:112)
