In Luke’s gospel, we are given the story of how the resurrected Jesus met two people as a stranger. According to this story, when two men were walking to Emmaus they met a stranger who started to walk and talk with them. They did not recognize him. But he was with them throughout the whole day. At the end of the day when He broke bread at the Eucharist they were able to recognize Him.
This gave them the realization that all human beings are created in the image of God and have the capacity to reflect the resurrected Jesus. This realization made the early Christians accept anyone into their fellowship irrespective of class, code, or ethnicity.
God the Ultimate Reality is calling us to experience this Emmaus Pilgrimage.
