On the walk to Emmaus, Jesus is first recognized as an alien.
An economic migrant—a desert nomad—leads his family toward a land of promise, believing he is following the will of his Creator. And so begins the great trek for new life, survival, redemption. He will find danger, so much danger that he plans to pass his wife off as his sister. It is a trek repeated today in the heat of the Sonoran desert, in boats from Africa running ashore in southern Europe, in the hulls of boats from Fujian province to the shores of Long Island.
