Thank you! I did not know where to get this information as our local parish priest was not really sure (I moved here to Poland a year ago and they don’t really know how to deal with marriages of Catholics to non-Christians!)
I have first hand experience with this. My husband didn’t swim the Tiber until the Easter after our marriage, but we still chose a Mass, because we wanted the grace and a mass.
My limited experience, with friends and such, if one of the parties is in RCIA, they often go with a mass.
