It looks like an individual dive in this situation if only because the expense of a party like that PLUS the liquor would be staggering. Not within a commoner’s discretionary budget.
The answer is God, notice I didn’t even say church... I know firsthand that churches can fail!
Having been a party of and target in a church megafail...
...there were times I said “Lord, save me from your ‘followers’ if You would, please?”
And they were absolutely certain they were doing His work.
Hence why I am unaffiliated, and make no mention of it if I don’t have to.
