Now that very day two of them were going to a village seven miles from Jerusalem called Emmaus, and they were conversing about all the things that had occurred. And it happened that while they were conversing and debating, Jesus himself drew near and walked with them, but their eyes were prevented from recognizing him. He asked them, "What are you discussing as you walk along?" They stopped, looking downcast…
And he said to them, "Oh, how foolish you are! How slow of heart to believe all that the prophets spoke! Was it not necessary that the Messiah should suffer these things and enter into his glory?" Then beginning with Moses and all the prophets, he interpreted to them what referred to him in all the scriptures…
And it happened that, while he was with them at table, he took bread, said the blessing, broke it, and gave it to them. With that their eyes were opened and they recognized him, but he vanished from their sight. (Lk 24, 13-35)
A beautiful story. Two disappointed disciples were on their way back home. All the miracles they had witnessed and all the teaching of Jesus were of no use to them at the moment. While they were walking they were also talking about the events of the days. They were true to fact about their narration of events (at least as the gospel presents). They were reading/narrating the events as they happened. They read the events humanly and historically and factually. They did not read the events theologically (in faith perspective).
Jesus came into the story as a passerby. He began to read the same events biblically (events as the fulfilment of the Old Testament). He read the same events in faith perspective. God was read into the events. All what happened were according to the plan of God, and in fact, God had revealed these things earlier, in scriptures.
Finally, they re-lived the breaking of the bread. This re-living made them experience the risen Jesus. This experience is sudden and short-lived. There was sufficient time to recognize him and as soon as thy recognized him he vanished from them. Historical reading, biblical reading, and theological reading are stages towards an experience. Jesus walks along until one gets this experience through these stages. But as soon as one recognizes the presence of the risen Lord, immediately He disappears. WHY? Because experience has to be lived, professed and proclaimed.
