It's you who doesn't understand the difference between socialism and communism. Socialism and communism are both systems of production for use based on public ownership of the means of production and centralised planning. 

Jesus never taught that private property or private wealth was intrinsically wrong. Indeed, He didn't hold economic seminars. We no longer live in the Garden of Eden. As St. Clement of Alexandria observed: “if no one possessed anything, it would be impossible to obey Jesus’ commandment to give to the poor.”

Origen’s commentary on St. Matthew concludes that people of wealth are often possessed by their riches; the riches give them the power to do as they please, and various temptations and sinful inclinations are therefore more difficult to resist.
