More info: :)
Before Reconciliation last week, I arrived early to pray the Rosary before the statue of Mary and Jesus. I was 45 minutes early. A Mass was being said when I arrived, which I have not encountered before. It was in Spanish, and at first, I thought of participating completely, as I arrived only a few minutes after it began.
However, it became clear after the Homily, that this was a Marriage ceremony, and I quickly changed my mind about receiving Communion. :( I did stand during the Lord's Prayer, but did not participate past the Wedding Vows other than that. I had stood/sat down the rest. I was at the side, towards the back of the building.
I knelt and continued praying the Rosary, with special intentions for the married couple. Many people were in line for Confession by the time Mass was over.
I think that there were extenuating circumstances, as we have a second, older Church building where weddings and Spanish Mass are usually celebrated; I think perhaps something went wrong that they were unable to hold it there as scheduled.
Did I do the right thing? Would you have left the building?
(And I ended up being there from 5:00-7:30! I prayed a lot; confessions started at 6:00 PM, and the line was super long, and I was unable to stand in line for that long, so I just continued praying in a pew until almost everyone had left, and then I got in line. Apparently, the First Communicants are doing their First Reconciliations on the regular Confession times, and many with their parents, so it's taking longer than usual, even with two priests. Not complaining at ALL, I am honored that I was able to partake for almost 3 hours!)
