The Didache

Now concerning the Thanksgiving, thus give thanks. First, concerning the cup: We thank thee, our Father, for the holy vine of David Thy servant, which Thou madest known to us through Jesus Thy Servant; to Thee be the glory for ever. And concerning the broken bread: We thank Thee, our Father, for the life and knowledge which Thou madest known to us through Jesus Thy Servant; to Thee be the glory for ever. Even as this broken bread was scattered over the hills, and was gathered together and became one, so let Thy Church be gathered together from the ends of the earth into Thy kingdom; for Thine is the glory and the power through Jesus Christ for ever. But let no one eat or drink of your Thanksgiving, but they who have been baptized into the name of the Lord; for concerning this also the Lord hath said, Give not that which is holy to the dogs.
