Funnily enough I went to a BBQ at the home of the only baptists I know on Monday. We had been eating for 5-10 minutes when I suddenly realised no one had said grace. I kinda felt guilty, I felt they had not said it because I was there.
I was bought up in a no-grace-ever-ever-ever household and I know this family usually say grace. Obviously they were very polite but I felt a bit guilty they broke their rules because I was in their house.
My dad actually used this as the prayer once or twice (certainly not when we had company!) He even used hand signals:
“Rub-a-dub-dub” (rub belly with one hand)
“Rub-a-dub-dub” (rub belly again)
“Yea God!” (raise hands and wave like you are at a revival)
“Thanks for the grub!” (said with hands folded in prayer)
No, pious wouldn’t be a good adjective to describe him…
Yet perhaps more sincere than the OP’s example.
Human developed propriety aside, it takes care of the basics:
While number 3, and therefore the “Yea, God” might be off-putting to some of your more radical atheists, even the most hard core can’t find fault with 1,2 and 4.
My cousins do the “rub-a-dub-dub-yea-God!” thing after saying the traditional “Bless Us, Oh Lord” prayer. They raise their hands in the air and everything. Since they’re kids, I think it’s cute, and I usually participate when I’m eating over at their house.
