I’ve been to both very poor small churches and very rich mega-churches. It’s hard to find legitimacy and authenticity in mega-churches and the services are productions.
I’ll take a poor country church any-day...
As Al Pacino as Scarface said about his WASP money laundering banker - “phonies.”
Mega churches become businesses. At that point, I do not need a middleman to talk to God. Small churches usually “get it.”
One of the last churches I went to was a more progressive Catholic church. It was not my choice but someone I was driving to church. I thought it was a business conference center. Where was the crucifix? The cross was invisible like the Holy ghost or something. Nutty.
