James Swan at AOM critiques a Catholic critique of the doctrine of sola scriptura.
Speaking of the Reformation, my thanks to John Bird for the reminder that it was on this day, April 18, in 1521 that Martin Luther stood before the Diet of Worms and uttered those famous words: "Since your majesty and your lordships desire a simple reply, I will answer without horns and without teeth. 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 cannot do otherwise, God help me. Amen."
