Sorry I can't answer that I am not Catholic.
My uncles exact words were “I need to find out if we can come”. He called back about two hours later and said “we are not allowed to attend”. My uncle is a former bishop, I don't know if that makes a difference.
It shouldn't; my dad attended with me at Methodist services whenever we went back to his home town (no Mormon church for over a hundred miles back then).
I always forgot to have some change for when they passed the plate. The last time I went, I gave my uncle a $50 and told him it was for all the times he'd put a couple of bucks in for me... He put it in the plate, LOL!
Thanks for reminding me of that, he died of Lou Gehrig's Disease a few years back, I miss him.
