Didache

Now concerning the Thanksgiving (Eucharist), 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 modest 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 (Eucharist), 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.

But after ye are filled, thus give thanks: We thank Thee, holy Father, for Thy holy name which Thou didst cause to tabernacle in our hearts, and for the knowledge and faith and immortality, which Thou modest known to us through Jesus Thy Servant; to Thee be the glory for ever. Thou, Master almighty, didst create all things for Thy name's sake; Thou gavest food and drink to men for enjoyment, that they might give thanks to Thee; but to us Thou didst freely give spiritual food and drink and life eternal through Thy Servant. Before all things we thank Thee that Thou art mighty; to Thee be the glory for ever. Remember, Lord, Thy Church, to deliver it from all evil and to make it perfect in Thy love, and gather it from the four winds, sanctified for Thy kingdom which Thou hast prepared for it; for Thine is the power and the glory for ever. Let grace come, and let this world pass away. Hosanna to the God (Son) of David! If any one is holy, let him come; if any one is not so, let him repent. Maran atha. Amen. But permit the prophets to make Thanksgiving as much as they desire.
