If communists started saying communism was a religion, we could point to their doctrines, which declare that religion is obsolete, and present that as compelling evidence that they were NOT sincere.

For what it’s worth, there are some Christian Communists:

Christian communism can be seen as a radical form of Christian socialism. It is a theological and political theory based upon the view that the teachings of Jesus Christ compel Christians to support communism as the ideal social system. Although there is no universal agreement on the exact date when Christian communism was founded, many Christian communists assert that evidence from the Bible suggests that the first Christians, including the Apostles, created their own small communist society in the years following Jesus’ death and resurrection. As such, many advocates of Christian communism argue that it was taught by Jesus and practiced by the Apostles themselves.

True, most religions are (partly) health/lifestyle guides
