The two disciples press him to stay with them as they draw near the town of Emmaus. Jesus sits down with them, takes bread, says the blessing, breaks it and gives it to them, and in that moment they recognize him. Though they were, through the mediation of Scripture, beginning to see, they still did not fully grasp who he was. But in the eucharistic moment, in the breaking of the bread, their eyes are opened.
The ultimate means by which we understand Jesus Christ is not the Scripture but the Eucharist, for the Eucharist is Christ himself, personally and actively present. The embodiment of the paschal mystery, the Eucharist is Jesus’ love for the world unto death, his journey into godforsakenness in order to save the most desperate of sinners, his heart broken open in compassion. And this is why it is through the lens of the Eucharist that Jesus comes most fully and vividly into focus.
Successful evangelists are persons of the Eucharist. They are immersed in the rhythms of the Mass; they practice eucharistic adoration; they draw the evangelized to a participation in the body and blood of Jesus. They know that bringing sinners to Jesus Christ is never primarily a matter of personal witness, or inspiring sermonizing, or even exposure to the patterns of the Scripture. It is primarily a matter of seeing the broken heart of God through the broken bread of the Eucharist.
So prospective evangelists, do what Jesus did. Walk with sinners, open the Book, break the Bread.
