Unless I am convicted by Scripture and plain reason—I do not accept the authority of popes and councils, for they have contradicted each other—my conscience is captive to the Word of God, I cannot and I will not recant anything, for to go against conscience is neither right nor safe. Here I stand. I can do no other. God help me. Amen.
April 18, 1521 in protest at the Diet of Worms
As recorded in Roland Bainton, Here I Stand, 180.
