I think that this pope is demonstrating a serious change than previous modern Popes.

Francis has decided to not live in the lush apartments that popes before him lived in, but to live in much more modest accommodations.

He also refuses to wear the red shoes, a symbol of wealth and power.

Peter (the first Pope) was a man of poverty, this pope as much as the Vatican goons will allow it, is a man who lives in as much poverty as he can.

He even paid his own hotel bill instead of sending a lackey to do that humble job.

Francis is appointing priests to positions, poor priests not rich men. He has chastised serious greedy spending of a few of the higher ups. He has made the bank books open to the public, something that hasn't been done in centuries.

He is very much doing as Peter would have done, turning the church from attending the needs of the rich and being 'the rich organization' to one that serves the poor, and turns from massive use of wealth.

While centuries of wealth can't just be dumped and the buildings and such are historical, and will undoubtedly remain for some time. The way the papacy will approach the display and use (using a modest apartment over the Popes lavish appointments, wearing black shoes over red ones) is a serious move.

Furthermore, this pope is not interested in carrying on doctrine, but seeks to be an organization that focuses on works and the needs of the flock not the doctrine.
