‘Now that same day two of them were going to a village called Emmaus, about seven miles from Jerusalem. They were talking with each other about everything that had happened. As they talked and discussed these things with each other, Jesus himself came up and walked along with them; but they were kept from recognizing him … He said to them, “How foolish you are, and how slow to believe all that the prophets have spoken! Did not the Messiah have to suffer these things and then enter his glory?” And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself … When he was at the table with them, he took bread, gave thanks, broke it and began to give it to them. Then their eyes were opened and they recognized him, and he disappeared from their sight. They asked each other, “Were not our hearts burning within us while he talked with us on the road and opened the Scriptures to us?”’ – Luke 24:13-16,25-27,30-32
Note the Liturgical character of this narrative. First the Scriptures are expounded then the breaking of the bread – the Liturgy of the Word and the Liturgy of the Eucharist. Jesus Christ is our high priest.
‘Then he took the book of the covenant, and read it in the hearing of the people … And Moses took the blood and threw it upon the people, and said, “Behold the blood of the covenant which the LORD has made with you in accordance with all these words.” Then Moses and Aaron, Nadab, and Abi′hu, and seventy of the elders of Israel went up, and they saw the God of Israel … they beheld God, and ate and drank.’ – Exodus 24:7a,8-10a,11b
We not only see God, but now we can KNOW Him. We know him in the Eucharist – in the breaking of the bread.
