Luther went to the emperor and the Roman Catholic Church in 1521 to defend his belief in Sola Scriptura.
"Unless I am convinced by Scripture and plain reason - I do not accept the authority of the 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. God help me. Amen."
