This is from one of the earliest church writings called the ” Didache”.  It is the prayer after communion.

We give you thanks, our Father, for the life and knowledge which you have made known to us through Jesus, your servant; to you be the glory forever. Just as this broken bread was scattered upon the mountains and then was gathered together and became one, so may your church be gathered together from the ends of the earth into your kingdom; for yours is the glory and the power through Jesus Christ forever.
