So, the eleven apprentices returned to Anytown, and on the hill where Jesus had taught them they found him again, and rededicated their lives to him – except, actually, not all of them did.
Jesus appeared to them there, saying, "By the authority I have over everything, I say you are no longer apprentices; you are journeymen. Now, wherever you go, make new apprentices, initiating them into the way I taught you: the way of all creation, all humanity, all life. Remember, I'll always be with you, to the very end."
Sooner or later, you've learned enough. You never know it all, but at some point you've learned enough to venture out on your own, and begin to teach what you do know to others. That's the way it's supposed to work. (Of course, as Matthew admits, there are actually some who, for any number of reasons, never quite get to that point.)
This last paragraph is Matthew's Commencement ceremony. Some call it the "Great Commission", but it's not as much a commandment as it is a recognition. Whatever will happen from here forward is up to them. They have what they need to carry on with the Jesus project.
The question for them and for us is: What now?
This weekend, Easter weekend, is our commencement. We have all we need to carry on with the Jesus project. What will we do with it? Where will we take it? Who will we choose as our apprentices?
Here's your diploma. Here's your license to practice the faith. It comes "with all the privlidges, duties and responsibilities thereof".
You're a journeyman now. So go ahead. It's up to you to make something of it.
