Quick background - I am a non-Catholic married to a Catholic. Last Friday my wife and I were doing a bit of volunteer work at the church. We were just finishing up when the priest (who is a great guy, has a really wonderful sense of humor, but is fairly new to our parish and does not know me that well) walked into the room, fully vested, and with a great flourish announced,“Your minister is here to serve you. It’s time for mass.” I looked at my watch and, sure enough, it was noon - time for the scheduled mass. Given his grand announcement, it didn’t seem right to tell him that we were just getting ready to go to McDonalds. So…off to mass. We got to the chapel and, much to my dismay, there were only three other people there - all very elderly and all with various mobility issues. I could see this dilemma coming from a mile away, and sure enough, when the time came, Father said, “Rick, can you come forward and give the readings?” Since I am a non-Catholic, I know this isn’t really kosher, but rather than cause a big disruption, I just did as Father asked.
Now, in my mind, this isn’t a big deal. I just read the words from the book. They would have sounded exactly the same if a Catholic had been reading them. However, I really do make an effort to be respectful and to follow the rules when I attend mass with my wife. So…with that in mind, did I commit a minor faux pas, or did I render the whole mass invalid? (Just kidding about the invalid mass part - you know what I mean.) How should I handle this if it comes up in the future?
