Here’s another idea, we did this in religious ed and the children loved it. One day we took them “behind the scenes” for a tour of the sacristy. The priest explained all the various vessels and things, the closet with all the vestments. This was fascinating to them. We had a “dry Mass” which is where you go thru the prayers and some motions, but it’s not sacramental, there is no consecration (not a real Mass), so that you can stop along the way and explain what the words mean, or what the priest is doing on the altar and why. We had a small group of adults attend, who just wanted to learn more about the Mass.
That’s very much what I was suggesting for a video presentation. Our RE program includes around 800 children, so it would be very difficult for Father to do something like this “live”!
That’s a great idea too.
