Christian communism is a theological view that the teachings of Jesus compel Christians to support religious communism. Although there is no universal agreement on the exact dates when communistic ideas and practices in Christianity began, many Christian communists argue that evidence from the Bible suggests that the first Christians, including the Apostles in the New Testament, established their own small communist society in the years following Jesus' death and resurrection. Many advocates of Christian communism and other communists, including Karl Kautsky, argue that it was taught by Jesus and practised by the apostles themselves. This is generally confirmed by historians.

Religious communism is a form of communism that incorporates religious principles. Scholars have used the term to describe a variety of social or religious movements throughout history that have favored the common ownership of property. There are many historical and ideological similarities between Religious communism and Liberation Theology.
