Prayer at the reception diner...

My Dad is going to say a prayer prior to dinner. I think it is a very nice way to include your grandparents at the reception.

Your DJ can introduce Grandpa and let him say the prayer then give the mic back to the DJ for whatever process you have in place to release by table.

LDS here. We didn't have a prayer for everyone. Honestly, public prayers aren't super common unless it's a ward activity

I love the idea! Even though you aren't religious, how thoughtful of you to think of this special opportunity for your grandparents. If it were me, I would have them pray over dinner after the bridal party is announced and immediately before the buffet line begins.

I'm not sure how customary it is, but I think it's a lovely idea regardless.

Giving praise TO God especially for a marriage before eating is always a good idea

I think that's very sweet. I would say to say the prayer after everyone is seated before the tables get called up.

The last wedding I went to, the Pastor said a quick prayer over the food before they started dismissing tables.

Thank you all for the input. I'll definitely be asking them if this is something they would like to do.

I'm atheist, but I have friends/family of multiple faiths. So if I'm in a situation where someone is saying a prayer I just just shut up, and look down at my hands, and respect that shit. So I would be fine with that at a wedding. It might be weird because I wouldn't expect it, and I may or may not subtly put down my fork and pretend like I wasn't already obliterating whatever I was eating because I wasn't expecting a prayer, but I think it would be fine if it was important to your grandparents.

A prayer is always a great thing to have at any wedding. It's very common. Even when you go to a college graduation they have prayers before and after the ceremony. So definitely have the prayer right before anyone gets up to eat

I love that idea, I'm having my close childhood friend pray before dinner
