The Gospel for this week is a follow-on to last Sunday’s Gospel. Then, people who came to Jesus’ tomb in the early morning found the tomb empty. Now, it is the evening of the same day, and the disciples are locked in a room, hiding from the people frenzied by the religious powers-that-were in those days. Locked door or no, Jesus is suddenly there with them.
He not only proves that it’s really him, he gives them their basic mission, one which we have to this day.
