They recognised him at the breaking of bread
Two of the disciples of Jesus were on their way to a village called Emmaus, seven miles from Jerusalem, and they were talking together about all that had happened. Now as they talked this over, Jesus himself came up and walked by their side; but something prevented them from recognising him. He said to them, ‘What matters are you discussing as you walk along?’ They stopped short, their faces downcast.
Then one of them, called Cleopas, answered him, ‘You must be the only person staying in Jerusalem who does not know the things that have been happening there these last few days.’ ‘What things?’ he asked. ‘All about Jesus of Nazareth’ they answered ‘who proved he was a great prophet by the things he said and did in the sight of God and of the whole people; and how our chief priests and our leaders handed him over to be sentenced to death, and had him crucified. Our own hope had been that he would be the one to set Israel free. And this is not all: two whole days have gone by since it all happened; and some women from our group have astounded us: they went to the tomb in the early morning, and when they did not find the body, they came back to tell us they had seen a vision of angels who declared he was alive. Some of our friends went to the tomb and found everything exactly as the women had reported, but of him they saw nothing.’
Then he said to them, ‘You foolish men! So slow to believe the full message of the prophets! Was it not ordained that the Christ should suffer and so enter into his glory?’ Then, starting with Moses and going through all the prophets, he explained to them the passages throughout the scriptures that were about himself.
When they drew near to the village to which they were going, he made as if to go on; but they pressed him to stay with them. ‘It is nearly evening’ they said ‘and the day is almost over.’ So he went in to stay with them. Now while he was with them at table, he took the bread and said the blessing; then he broke it and handed it to them. And their eyes were opened and they recognised him; but he had vanished from their sight. Then they said to each other, ‘Did not our hearts burn within us as he talked to us on the road and explained the scriptures to us?’
They set out that instant and returned to Jerusalem. There they found the Eleven assembled together with their companions, who said to them, ‘Yes, it is true. The Lord has risen and has appeared to Simon.’ Then they told their story of what had happened on the road and how they had recognised him at the breaking of bread.

WHAT IS THIS SACRAMENT CALLED?
1328 The inexhaustible richness of this sacrament is expressed in the different names we give it. Each name evokes certain aspects of it. It is called:
Eucharist, because it is an action of thanksgiving to God. The Greek words eucharistein and eulogein recall the Jewish blessings that proclaim – especially during a meal – God’s works: creation, redemption, and sanctification.
1329 The Lord’s Supper, because of its connection with the supper which the Lord took with his disciples on the eve of his Passion and because it anticipates the wedding feast of the Lamb in the heavenly Jerusalem.
The Breaking of Bread, because Jesus used this rite, part of a Jewish meat when as master of the table he blessed and distributed the bread, above all at the Last Supper. It is by this action that his disciples will recognize him after his Resurrection, and it is this expression that the first Christians will use to designate their Eucharistic assemblies; by doing so they signified that all who eat the one broken bread, Christ, enter into communion with him and form but one body in him.
The Eucharistic assembly (synaxis), because the Eucharist is celebrated amid the assembly of the faithful, the visible expression of the Church.
1330 The memorial of the Lord’s Passion and Resurrection.
The Holy Sacrifice, because it makes present the one sacrifice of Christ the Savior and includes the Church’s offering. The terms holy sacrifice of the Mass, “sacrifice of praise,” spiritual sacrifice, pure and holy sacrifice are also used, since it completes and surpasses all the sacrifices of the Old Covenant.
The Holy and Divine Liturgy, because the Church’s whole liturgy finds its center and most intense expression in the celebration of this sacrament; in the same sense we also call its celebration the Sacred Mysteries. We speak of the Most Blessed Sacrament because it is the Sacrament of sacraments. The Eucharistic species reserved in the tabernacle are designated by this same name.
1331 Holy Communion, because by this sacrament we unite ourselves to Christ, who makes us sharers in his Body and Blood to form a single body. We also call it: the holy things (ta hagia; sancta) – the first meaning of the phrase “communion of saints” in the Apostles’ Creed – the bread of angels, bread from heaven, medicine of immortality, viaticum. . . .
1332 Holy Mass (Missa), because the liturgy in which the mystery of salvation is accomplished concludes with the sending forth (missio) of the faithful, so that they may fulfill God’s will in their daily lives.
Bless the LORD, my soul! LORD, my God, you are great indeed! You are clothed with majesty and glory,
robed in light as with a cloak. You spread out the heavens like a tent;
you raised your palace upon the waters. You make the clouds your chariot; you travel on the wings of the wind.
You make the winds your messengers; flaming fire, your ministers.
You fixed the earth on its foundation, never to be moved.
The ocean covered it like a garment; above the mountains stood the waters.
At your roar they took flight; at the sound of your thunder they fled.
They rushed up the mountains, down the valleys to the place you had fixed for them.
You set a limit they cannot pass; never again will they cover the earth.
You made springs flow into channels that wind among the mountains.
They give drink to every beast of the field; here wild asses quench their thirst.
Beside them the birds of heaven nest; among the branches they sing.
You water the mountains from your palace; by your labor the earth abounds.
You raise grass for the cattle and plants for our beasts of burden. You bring bread from the earth,
and wine to gladden our hearts, Oil to make our faces gleam, food to build our strength.
The trees of the LORD drink their fill, the cedars of Lebanon, which you planted.
There the birds build their nests; junipers are the home of the stork.
The high mountains are for wild goats; the rocky cliffs, a refuge for badgers.
You made the moon to mark the seasons, the sun that knows the hour of its setting.
You bring darkness and night falls, then all the beasts of the forest roam abroad.
Young lions roar for prey; they seek their food from God.
When the sun rises, they steal away and rest in their dens.
People go forth to their work, to their labor till evening falls.
How varied are your works, LORD! In wisdom you have wrought them all; the earth is full of your creatures.
Look at the sea, great and wide! It teems with countless beings, living things both large and small.
Here ships ply their course; here Leviathan, your creature, plays.
All of these look to you to give them food in due time.
When you give to them, they gather; when you open your hand, they are well filled.
When you hide your face, they are lost. When you take away their breath, they perish and return to the dust from which they came.
When you send forth your breath, they are created, and you renew the face of the earth.
May the glory of the LORD endure forever; may the LORD be glad in these works!
If God glares at the earth, it trembles; if God touches the mountains, they smoke!
I will sing to the LORD all my life; I will sing praise to my God while I live.
May my theme be pleasing to God; I will rejoice in the LORD.
May sinners vanish from the earth, and the wicked be no more. Bless the LORD, my soul! Hallelujah!
