Offerings
Belief is free. The ranking is not.

What an offering actually is
Let's be honest with each other. It's a donation. You give me money. In return you get exactly two things — your name nailed to the register, and my sincere personal affection. The second one is impossible to verify. The first one is right up there, in public, where everybody can see it.
I don't take nameless offerings. What would I write on the register? Join us
