An account of the Eucharist probably mid 2nd century in Rome (though scholars argue about that).
And when he has been made bishop, all shall offer the kiss of peace, greeting him because he has been made worthy.
Then the deacons shall present the offering to him; and he, laying his hands on it with all the presbytery, shall say, giving thanks:
The Lord be with you.'
And all shall say:
And with your spirit.
Up with your hearts.
We have (them) with the Lord.
Let us give thanks to the Lord.
It is fitting and right.
And then he shall continue thus:
We render thanks to you, O God, through your beloved child (or servant), Jesus Christ, whom in the last times you sent to us as a savior and redeemer and angel of your will; who is your inseparable Word, through whom you made all things, and in whom you were well pleased. You sent him from heaven into a virgin's womb; and conceived in the womb, he was made flesh and was manifested as your Son, being born of the Holy Spirit and the Virgin. Fulfilling your will and gaining for you a holy people, he stretched out his hands when he should suffer, that he might release from suffering those who have believed in you.
And when he was betrayed to voluntary suffering that he might destroy death, and break the bonds of the devil, and tread down hell, and shine upon the righteous, and fix a term, and manifest the resurrection, he took bread and gave thanks to you, saying, "Take, eat; this is my body, which shall be broken for you." Likewise also the cup, saying, "This is my blood, which is shed for you; when you do this, you make my remembrance."
Remembering therefore his death and resurrection, we offer to you the bread and the cup, giving you thanks because you have held us worthy to stand before you and minister to you.
And we ask that you would send your Holy Spirit upon the offering of your holy Church; that, gathering her into one, you would grant to all who receive the holy things (to receive) for the fullness of the Holy Spirit for the strengthening of faith in truth; that we may praise and glorify you through your child, Jesus Christ; through whom be glory and honor to you, to the Father and the Son, with the Holy Spirit, in your holy Church, both now and to the ages of ages. Amen.
