Who is he to judge ???

He's the Pope, for God's sake! If he won't judge, how can anyone?

Jesus said this:

Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.

-Matthew 5:17-18 KJV

The real question is this: what is the law, how shall it be fulfilled, and by whom?
