The difference between communism and heaven sharing is that communism has to be forced by people that take extra in order to enforce it and the heavenly way is voluntary within a community that all are of the same heart and mind.

For the pope to promote sharing of property with out first talking about the deep spirituality required is preparing/brainwashing people to accept the communist way. There is a reason they put walls in Berlin which is to keep people locked in the communist hell they made.
