In today's Gospel, Jesus appears to his apostles after his violent and humiliating death on the cross, and they are terrified because they think he is a ghost! And rightfully so because ghosts are scary! (For why we think this, listen to the podcast.) But to show that he is not a ghost, he makes it a point to allow the disciples to touch his body, and then he eats a piece of fish in front of them. All of this to show them that it is he, himself: Jesus, the One whom they have known and the One who knows them. It is this same Jesus who still lives today, and because He lives, a real relationship is possible with Him.
