I would argue that the best summation of Christian ethics is found in the sermon on the plain in Luke 6:20–49. What I love about the sermon on the plain is just how radical it seems on the surface, it seems almost impossible; however, when you think about what it’s saying, and think about it deeply—it makes sense. Probably my favorite example of this is found in Luke 6:34–35 (NRSV):
The early Christian Communities practiced communism, here’s how we know.
When I wrote the book All Things in Common, The Economic Practices of the Early Christians some people suggested I drop my use of the term ”communism” from the text; their reasoning was sound: the term communism has many negative connotations. When most people hear the world “communism”, they think of one of two things: totalitarian regimes such as Stalinist Russia or Maoist China, or some far off utopia where the entire world lives without any property whatsoever or any state. The actual classical meaning of the word, the meaning that actually represents something in reality, is basically nothing more than any social-relationship or structure where the principle of “from each according to his ability to each according to his need” is the primary moral framework of the social relationship or structure. Instead of replacing the term with something else, I went through the trouble of breaking down what communism actually means and contrasting it with other principles of social-relationships like hierarchy or exchange. The reason I stuck with the term “communism” was simple: that term is simply the most fitting term for the economic practices of the early Christians that differentiated them from the larger Roman world; the more I studied the issue the more I became convinced of that.
