No judgment in what you ultimately decide, I just thought I’d share my own thoughts on Eucharist at weddings.
I converted to Catholicism just before my husband I were married. I believed in the Real Presence, but I also had friends and family that were…problematic. Several protestant “friends” at the time and my family made it perfectly clear to me, when I explained the etiquette at a Catholic Mass, that they intended to receive no matter what. When I asked them not to out of consideration and respect for, if not my religious beliefs, than me on my wedding day, they outright refused. I wasn’t ready to sever relationships with these people yet, and disinviting them to my wedding would certainly have done that (though the relationships did end over time…) so I made a decision that to this day I deeply and sorely regret - my husband and I agreed not to have a full Mass.
I couldn’t bear the thought of people using our wedding Mass as a chance to profane Jesus for their own pride. I also couldn’t bear the thought of creating a situation where Jesus was withheld from the believing Catholics in his family while some people received.
If I had it to do all over again, especially now knowing how precious Eucharist is, I would have done it. I would have had a full Mass and gone over with the priest what several guests intended to do and let him help me figure it out. Actually, if I had it to do all over again I would have straight up disinvited those people and realized that people (be they family or friends) who are so abusive of someone that they can’t do something as simple as STAY IN THEIR SEAT is NOT someone you really want to have around in any kind of close relationship.
