Beck is right. Mainstream Religion has been going this route for a long time. Any organization that is a member of the World Council of Churches, or the National Council of Churches is basically an arm of the Communist party.
That said, Beck’s warning rings hollow when you realize he doesn’t run from his own cult which is steeped in the hallucinogenic rantings of a sexual pervert.
I can’t really trust Beck on anything religious. He has obviously not investigated his own faith as much as he has investigated other things or he wouldn’t be Mormon.
That said, I see a clear division in the Church. The Libs who are WCC and place social problems ahead of the Gospel, and the Conservative churches, many of whom see that the cure for social ills is the same cure as spiritual ills, Jesus Christ.
