How do you expect a heretic to clean house?
You are a 'heretic'? The 'clean house' was for non-heretical Catholics. Get rid of that stooge. Now you know how Luther felt about his pope.
Sigh. Let me simplify it for you:
+Catholic pope excommunicates a heretic, Martin Luther.
+Said heretic starts his own religion.
+Current pope attempts to rehabilitate said heretic and actually celebrates his revolt.
+ergo, current pope is a heretic.
