"The words socialism and communism were used almost interchangeably in the beginnings of the socialist movement, prior to the formation of communism as a distinct movement. People chose to use one or the other on the basis of perceived attitude to religion. In Europe communism was considered to be the more atheistic of the two; whereas in England that sounded too close to communion with Catholic overtones, hence atheists preferred to call themselves socialists."
