(We had this Gospel on a weekday some time ago. So, if you don't mind, I'll repeat what I wrote then.)
In all the Bible stories about the Risen Christ no one recognized him. I’m sure there is a lesson for us their, but I do not know what it is. Perhaps it is meant to alert us to a need to recognize him when he comes to us in different forms.
The two disciples seem to have missed Our Lord’s real message. They thought him a failure when he did not take advantage of his popularity to drive out the Romans.
Don’t you wish they could have recorded it when “Beginning with Moses and all the prophets he interpreted for them what referred to him in all the Scriptures” The two of them later said that their hearts were burning inside of them as he explained the Scriptures.
They later spoke of “how he was made known to them in the breaking of the bread.” I don’t think that his bread-breaking had a distinctive snap crackle pop to it. For a time in the First Century the Mass was known simply as “the breaking of the bread.” Although Jesus that night might have stopped short of offering a Eucharist, his words and actions must have followed his distinctive ritual for the blessing at the Last Supper.
The long day’s walk had wearied the disciples, but dining with Jesus had energized them for sprinting back to the gathering of disciples in Jerusalem.
