What is Roger Waters Religion?

I don't know if this has already been covered but I was wondering what is Rogers religion? In his solo albums he sings a lot about religion. If anyone knows just let me know. Thanks.

Waters does not subscribe to any religion; he is quite vocal about his atheist views and highly critical of religious attitudes.

I found it interesting that his father Eric Fletcher Waters was staunchly opposed to fighting in WWII on the basis of Christian values, but then changed his mind when he became politically active in British Communism.
