Thought this was interesting thread so I hope you don't mind me butting in here a bit.
We say 3 prayers at family gatherings
"Bless us, O Lord, and these thy gifts for which we are about to receive. From thy bounty, through Christ, our Lord, Amen."
"Come Lord Jesus, be our Guest, let these gifts to us be blessed. Amen."
"We thank thee Lord for happy hearts, for rain and sunny weather. We thank thee Lord for this our food, and we are here together. Amen"
In that order.
I know the first 2 are for the people in our family that are Roman Catholic which is most. The 2nd is for the Lutherans which are a few.
For the life of me I have no idea where the 3rd came from or who it's for. I can't think of anyone in our family who doesn't either identify as a Roman Catholic or a Lutheran.
