i do believe that Pope Francis will reform the Vatican by cracking down on many levels including corruption, pedophilia, and the Vatican's finances. I especially like that while remaining to God's word about social issues including homosexuality this Pope does not take a position of judgment, but instead caring, and understanding.
The Catholic Church is not going to change any time soon. Although Francis might make a few small adjustments in policies for public relations purposes, it is highly unlikely that he will make any substantive reforms. The Church has not changed in 2,000 years, and it's not going to because of one new Pope.
