Oh, we are back to "God causes sin" again...I forgot you guys believe that. More properly, God ALLOWED it to happen. Without it, the Council of Trent wouldn't have come about in its form, nor would the Counter Reformation. See? God brings about great good even out of evil!
Now come on, in Catholicism, nothing is ever REALLY done, is it? :)
We are told to persevere. Until the end. Take it up with the Sacred Scriptures that you purport to support.
We're still Heeeeeere. :) Therefore, God must have fully ordained and commanded the Reformation.
The Old Testament story of Korah is not meant to be taken as a literal example for future rebels to God's People. Does the Earth open up and swallow atheists today? Hitler? Stalin? The point of the story is to say that God WILL punish such people. In the context, God condemns such ring leaders to hell, eternal death. I'd rethink your logic.

Jokus-Oh, we are back to "God causes sin" again
Hmmmmm......
Perhaps it has never occurred to you that the Reformation might not have been sinful? :O)
