John's Gospel begins the resurrection story with the detail that Mary Magdalene goes to the tomb while it is still dark. Caleb suggests that we ought to bring the darkness of our doubts, the darkness of our griefs and of our disappointments with us to Easter. Secondly, he points out that no one recognizes Jesus at first. It is difficult to see the risen Jesus, for the disciples and for us. Until Jesus calls Mary by her name, and Peter by his (three times!), they do not really believe that Easter has changed the world.
