Luther had no use for reason. Indeed, he hated it, once called it: "that damned whore," obviously because it acted contrary to the faith which Luther apparently set above all things. Worse, he endorses lying for his god for the good of his church. Makes me wonder how he feels about the ninth commandment, then.
Thanks to AronRa and his Third Foundational Falsehood of Creationism, from which I got these graphics.
