Now, the 9th chapter of the Didache, concerning the Eucharist, does not indeed make any mention of any ‘words of institution’, but we need not jump to the conclusion (as J.D. Crossan argues) that the tradition as reflected in the NT accounts are later and that the Didache is the earlier stage. It could well be that it assumes the traditional core and attests simply the addition of thanksgiving prayers deemed appropriate in a more liturgically solemnized act (cf. Didache 10). John’s gospel also does not say anything about the supper, but there are eucharistic overtones elsewhere in the work (John 6).
Now concerning the Eucharist, give thanks this way. 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 Eucharist, unless they have been baptized into the name of the Lord; for concerning this also the Lord has said, “Give not that which is holy to the dogs.”
Now, it is a fair question as to whether in the earliest form Jesus is remembered as celebrating a Passover meal or instituting a new ritual to be repeated. On the latter issue, A does not say so, and the call for or assumption of memorial and repetition is a distinctive feature of B and 1 Corinthians 11:25b-26. Nevertheless the characteristics of oral tradition remain clear: a concern to retain the key elements of Jesus’ words as carefully as necessary, with a flexibility (including elaboration) which in this case no doubt reflects the developing liturgical traditions of different churches.
When he was about to surrender himself to voluntary suffering in order to destroy death, to break the devil’s chains, to tread hell underfoot, to pour out his light upon the just, to establish the covenant and manifest resurrection, he took bread, gave you thanks and said, “
Take, eat; this is my body which is broken for you.”
In like manner for the cup, he said, “
This is my blood which is poured out for you. When you do this, do this in commemoration of me.”
-From the Anaphora of Hippolytus
Together with these blessed powers, Master who loves mankind, we also proclaim and say: You are holy and all-holy, you and your only-begotten Son and your Holy Spirit. You are holy and all-holy, and sublime is your glory. You so loved your world that you gave your only-begotten Son so that whoever believes in Him should not perish, but have eternal life. He came and fulfilled the divine plan for us.
On the night when He was handed over, or rather when He handed Himself over for the life of the world, He took bread in His holy, pure, and blameless hands, gave thanks, blessed, sanctified, broke and gave to His holy disciples and apostles, saying, “
Take, eat; this is my body which is broken for you, for the remission of sins.”
R: Amen.
Likewise, after supper, He took the cup, saying, “
Drink of it, all of you; this is my blood of the new covenant which is shed for you and for many for the remission of sins.”
R: Amen.
-From the Divine Liturgy of St. John Chrysostom
We beg you, God, to deign to make this offering in every way blessed, approved, ratified, right and acceptable, so that it may become for our benefit the Body and Blood of your dearly beloved Son, our Lord Jesus Christ; who, the day before he suffered, took bread in his holy and venerable hands, and having raised His eyes to heaven to you, God, His Almighty Father, giving thanks to you, he blessed, broke, and gave it to his disciples, saying, “
Take and eat of this, all of you: for this is my body.”
Similarly, when the supper was ended, taking also this excellent chalice into his holy and venerable hands; again giving thanks to you, he blessed, and gave it to his disciples, saying: “
Take and drink of this, all of you, for this is the cup of my blood, of the new and eternal covenant; the mystery of faith: which will be shed for you and for many for the remission of sins. As often as you shall do these things, you shall do in memory of me.”
Our Lord Jesus Christ, on the night in which He was handed over, took bread: and, giving thanks, blessed and broke: and gave to His disciples, saying, “
Take and eat; this is my body which will be given up for you. As often as you shall eat, this do in commemoration of me.”
Likewise also the chalice, after He had supped, saying, “
This cup is the new covenant in my blood, which will be shed for you and for many for the remission of sins. As often as you shall drink, this do in commemoration of me.”
