Some Christian denominationsCatechism of the Catholic Church, "The institution of the Eucharist"John Anthony McGuckin, The Encyclopedia of Eastern Orthodox Christianity (Wiley-Blackwell 2011 ), Eucharist article by MC Steenberg vol. 1, p. 231Colin Buchanan, The A to Z of Anglicanism (Scarecrow Press 2009 ), p. 107 place the origin of the Eucharist in the Last Supper of Jesus with his disciples, at which he is believed to have taken bread and given it to his disciples, telling them to eat of it, because it was his body, and to have taken a cup and given it to his disciples, telling them to drink of it because it was the cup of the covenant in his blood.Enrico Mazza, Celebration of the Eucharist: The Origin of the Rite and the Development of Its Interpretation (Liturgical Press 1999 ), p. 19 Quotation concerning the origin: "The Christian Eucharist has its origin in the Last Supper. There, Jesus took bread, blessed God, broke the bread, and gave it to his disciples, telling them to take it and eat of it, because it was his body. In the same way, after they had eaten, he took the cup, gave thanks, and gave it to his disciples, telling them all to take it and drink of it, because it was the cup of the covenant in his blood as redemption of sin for many (Matthew 26:26–28). At the end he said: "Do this in remembrance of me."

The earliest extant written account of a Christian (Greek for 'thanksgiving') is that in the First Epistle to the Corinthians (around AD 55),. See also First Epistle to the Corinthians#Time and Place in which Paul the Apostle relates "eating the bread and drinking the cup of the Lord" in the celebration of a "Supper of the Lord" to the Last Supper of Jesus some 25 years earlier. Paul considers that in celebrating the rite they were fulfilling a mandate to do so.Encyclopædia Britannica, s.v. Eucharist The Acts of the Apostles presents the early Christians as meeting for "the breaking of bread" as some sort of ceremony.

Writing around the middle of the second century, Justin Martyr gives the oldest descriptions of something that can be recognised as the rite that is in use today, according to K.W. Noakes. Earlier sources, such as the Didache, 1 Clement and Ignatius of Antioch provide glimpses of what Christians were doing in their Eucharists. Later sources, Tertullian and the Apostolic Tradition, offer some details from around the year 200. Even before the Church "went public" after the conversion of Constantine the Great in the second decade of the fourth century, it was clear that the Eucharist was a central part of Christian life and worship.

Scholars seeking to understand Christian practice debate whether Jesus meant to institute a ritual at his Last Supper;Crossan, John Dominic, The Historical Jesus, pp. 360–367 whether the Last Supper was an actual historical event in any way related to the undisputed early "Lord's Supper" or "Eucharist"Bradshaw, Paul, Eucharistic Origins (London, SPCK, 2004) , p. 10. and have asked if the Eucharist had its origins in a pagan context, where dinners to memorialize the dead were common.

Old Testament accounts

Book of Judges The supper at Emmaus (Luke 24:28–35) is reminiscent of the Book of Judges: the vocation of Gideon and the prophecy made to Manoach and to the barren woman of the birth of Samson. In both cases, the angel of the Lord appears and is not recognized as such. He carries a message: deliverance for Israel for Gideon and birth of Samson for Manoach and his wife. Each time, those who are visited prepare a sacrifice at the request of the mysterious host: kid and unleavened bread for Gideon; kid and vegetable offering for Manoach. In both cases, it is the sacrifice that reveals the identity of the host:

"And the angel of God said unto him, Take the flesh and the unleavened cakes, and lay them upon this rock, and pour out the broth. And he did so. Then the angel of Jehovah put forth the end of the staff that was in his hand, and touched the flesh and the unleavened cakes; and there went up fire out of the rock, and consumed the flesh and the unleavened cakes; and the angel of Jehovah departed out of his sight. And Gideon saw that he was the angel of Jehovah; and Gideon said, Alas, O Lord Jehovah! forasmuch as I have seen the angel of Jehovah face to face." "So Manoah took the kid with the meal-offering, and offered it upon the rock unto Jehovah: and the angel did wondrously, and Manoah and his wife looked on. For it came to pass, when the flame went up toward heaven from off the altar, that the angel of Jehovah ascended in the flame of the altar: and Manoah and his wife looked on; and they fell on their faces to the ground. But the angel of Jehovah did no more appear to Manoah or to his wife. Then Manoah knew that he was the angel of Jehovah."

These two events have parallel scenes in the New Testament: the same day that the empty tomb of Jesus is discovered, two disciples "were going to a village called Emmaus". A mysterious traveler joins them and questions them about the cause of their dejection. After listening to them, the traveller explains the events from the scriptures, then "when he had sat down with them to meat, he took the bread and blessed; and breaking it he gave to them. And their eyes were opened, and they knew him; and he vanished out of their sight".

These prefigurations and their realization shed light on the sacrificial nature of the Last Supper: on one hand, the Eucharist shows the paradoxical nature of this breaking of the bread which attests to a presence while keeping it invisible to the eyes of the two disciples; on the other hand, the sacrifice makes it possible to recognize the one who has manifested himself: it is at the moment when Jesus gives thanks, breaks the bread and gives it to the disciples of Emmaus that they recognize him.

Malachi In the Old Testament, the prophet Malachi exposes God's plans concerning the sacrifices which were offered to him in the temple of Jerusalem and as for the offerings which offered to him in the future: "Oh that there were one among you that would shut the doors, that ye might not kindle fire on mine altar in vain! I have no pleasure in you, saith Jehovah of hosts, neither will I accept an offering at your hand. For from the rising of the sun even unto the going down of the same my name shall be great among the Gentiles; and in every place incense shall be offered unto my name, and a pure offering: for my name shall be great among the Gentiles, saith Jehovah of hosts." According to Irenaeus, God, "by these words, he shows in the plainest manner that the former people [the Jews] shall cease to make offering to God, but that in every place sacrifices shall be offered to God, one that is pure, and that God's name is glorified among nations." Malachi prophesied the celebration of the Lord's Supper, all over the world, as a sacrificial meal, in place of the vegetable offerings and thanksgiving sacrifices that were offered in the Temple.

New Testament accounts

Institution narratives In the New Testament there are four accounts of the institution of the Eucharist, the earliest by St Paul in his first letter to the Corinthians which links it back to the Last Supper and three in the Synoptic Gospels in the context of that same meal., ,

+ Paul and the Synoptic Gospels in parallel columns 1 Corinthians 11:23–26 Mark 14:22–25 Matthew 26:26–29 Luke 22:14–20 "For I received from the Lord what I also handed on to you, that the Lord Jesus on the night when he was betrayed took a loaf of bread, and when he had given thanks, he broke it and said, 'This is my body that is broken for you. Do this in remembrance of me.' In the same way he took the cup also, after supper, saying, 'This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.' For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes." "While they were eating, he took a loaf of bread, and after blessing it he broke it, gave it to them, and said, 'Take; this is my body.' Then he took a cup, and after giving thanks he gave it to them, and all of them drank from it. He said to them, 'This is my blood of the covenant, which is poured out for many. Truly I tell you, I will never again drink of the fruit of the vine until that day when I drink it new in the kingdom of God.'" "While they were eating, Jesus took a loaf of bread, and after blessing it he broke it, gave it to the disciples, and said, 'Take, eat; this is my body.' Then he took a cup, and after giving thanks he gave it to them, saying, 'Drink from it, all of you; for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. I tell you, I will never again drink of this fruit of the vine until that day when I drink it new with you in my Father's kingdom.'" "When the hour came, he took his place at the table, and the apostles with him. He said to them, 'I have eagerly desired to eat this Passover with you before I suffer; for I tell you, I will not eat it until it is fulfilled in the kingdom of God.' Then he took a cup, and after giving thanks he said, 'Take this and divide it among yourselves; for I tell you that from now on I will not drink of the fruit of the vine until the kingdom of God comes.'

Then he took a loaf of bread, and when he had given thanks, he broke it and gave it to them, saying, 'This is my body, which is given for you. Do this in remembrance of me.' And he did the same with the cup after supper, saying, 'This cup that is poured out for you is the new covenant in my blood.[']"

Matthew likely follows the account found in the Gospel of Mark. Luke's version differs at so many points from the Markan that some scholars believe it stems from another source. John, which does not include an "Institution Narrative", includes an account of a supper on the night Jesus was betrayed, including a foot washing scene. Chapters 13–17 of the Gospel of John attribute to Jesus a series of teachings and prayers at his Last Supper, but does not mention any meal rituals. On the other hand, John 6, in particular verses such as 55–56 ("For my flesh is food indeed, and my blood is drink indeed. He who eats my flesh and drinks my blood abides in me, and I in him"), is widely interpreted as an allusion to the Eucharist.For instance, John 6, The Eucharist, and Protestant Objections; The Institution of the Eucharist in Scripture, etc. Perkins identifies reflections of the liturgical tradition of the Johannine community in the passage, though a growing number of scholars have challenged the idea of a Johannine community and cite the lack of evidence for such a community, and there is no consensus among scholars today. A passage found in Luke records a command, found also in Paul, to his disciples, to "do this as my memorial" without specifying whether it should be performed annually, like the Passover, or more frequently.

The text of the Lucan version is uncertain. A number of commentators conclude that the second half of 22:19 and all of 22:20 are later interpolations. In 1926 E.C. Ratcliff declared: "The textus receptus indeed includes the command, but the passage in which it occurs is an interpolation of the Pauline account; and whatever view be taken of the Lucan text, the command is no part of the original".Encyclopædia Britannica 13th Edition (1926) art. Eucharist However, C.P.M. Jones, writing in 1978, comments "Many scholars[...] have returned to the support of the longer text", and the same position was taken by the majority of editors of the United Bible Societies Greek New Testament. The attribution to Jesus of the words "This do in memory of Me" is therefore possible, but not certain. Jeremias says "Do this in remembrance of me" would better be translated "That God may remember me", but Richardson objects that the "presence of one particular meaning must not be taken to exclude other shades of meaning, and overtones".
