My son is having secular wedding
I’m so devastated. My son is getting married in October. I kept reminding him last year to contact our parish as one of the first steps of wedding planning. After asking a few times and receiving noncommittal responses, I started worrying. His fiancé is Catholic so I never gave a second thought about their understanding that marriage is a sacrament, not just a party and license from the government. His fiancés uncle is getting some type of certification or license to perform the ceremony at the same place wheee the reception will be.
I’m devastated and I can’t change their minds, I’ve tried. Is there anything they can do after the fact if, hopefully, they realized they made a mistake?
