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.

There are those who view that the early Christian Church, such as that one described in the Acts of the Apostles, was an early form of communism and religious socialism. The view is that communism was just Christianity in practice and Jesus was the first communist. This link was highlighted in one of Karl Marx's early writings, which stated that "[a]s Christ is the intermediary unto whom man unburdens all his divinity, all his religious bonds, so the state is the mediator unto which he transfers all his Godlessness, all his human liberty."
