If I had to guess, I truly believe Chrissy is falling for the Keith Craft cult.
Keith craft is basically a generic version of Houston's Joel Osteen. He has a huge loyal following @ his mega church. If you've ever seen these mega churches, the audience is a huge cult who looks up to their leader (keith craft in this case) and they give him tons of money. Also, churches don't have to pay taxes......we know how Chrissy likes to avoid paying taxes.
Chrissy is no longer mesmerized by the lights of Vegas. He sees thislarger than life version himself in Keith Craft and is dumb enough to believe he can learn the ins and outs from Craft and replicate it himself and become this fake church guro that has a huge following and don't have to pay taxes.
Change your life Megachurch coming soon.
I could even see Chrissy eventually turning on his gambling days saying "gambling is a sin" and "I don't gamble 99% of the time (much like his 99% Vegan).
This won't work though because Chrissy is such an unlikeable character and super condescending towards others naturally.
He'll realize this scam won't work and will move on to the next scam within the next 6-12 months. In the meantime He'll continue with the gambling scam.
