We are not entirely sure about the system known as Communism other than what we have assumed from contact with countries like China and Russia which are supposedly Communism. The concept of communism was actually begun by the disciples of Jesus Christ following his resurrection. The system was a communal one where the disciples and their spouses lived in a community sharing and working together. Much of the writings of the New Testament including those of Paul point out to a community of rulers called bishops who were in charge of giving the members of the community their share of living expenses from the community pool of money. The pool of money was made from donations given by old and new members.
The reality on a large scale of communism has proven to be contradictory. The Chinese have managed to make communism work since they were already accustomed to working for the good of the people. Their labor and their assets were expected to go to the central pot to be shared equally by all. Problems with some members who felt that their share was not equal to what they gave or who held back a portion of what they earned is the reality both at the time of inception of Communism in the Old Testament and what has been reported today from China and Russia. The two important sources of Communism, the writings of the disciples of Jesus Christ in the Old Testament and The Communist Manifesto are the concept, the reality is the societies of Russia and China and what we assume to be their usage of Communism.
