Nearly ALL churches have been infected with the “building program” bug - and when you have multi-million dollar mortgages for toys which substitute for the Holy Spirit, you have to keep your paying “customers” happy.
I think that the small churches out in the rural areas are still solid.The mega churces always seemed to be more about entertainment than the truth of the gospel.
