Luther was one passionate preacher; he spared no words. In his sermon on the Pharisee and the publican from Luke 18, he contrasts these two sinners:

Now see, what a disgraceful, monstrous devil is in such a beautiful saint, who can cover himself with a thin appearance of a few works which he performs before the eyes of the people, and what he does in his worship, thanks and prayers, whereby he blasphemes and dishonors the high majesty with outrage and defiance in the open public, that he dares to boast before God of such scandalous vices, and be so brave as though God were bound to treat him as a model saint, and as a debt and duty give him heaven and everything he might ask. Or if he knew that God would not do it, and accept the poor publican in preference to himself, he would be so enraged, with anger and hatred against God, as to publicly take the word out of God’s mouth and say, that he is not God but the devil from hell, and would gladly if he could, thrust him down from his throne and usurp his seat. And in all this he will not suffer himself to be punished by any one and will claim he did just right; whereas he deserves more than all other blasphemers, that God should at once open the earth and devour him alive.
