If it’s a question of ritual, which I understand, couldn’t Accomodations have been made for the Protestants present to do communion separately?
I’m not sure what you mean by an accommodation for
Protestants to “do communion separately” . Do you mean they would have a Liturgy and have their own ministers consecrate their own Eucharist? Or do you mean they would bring along previously consecrated bread and wine to distribute to their own members?
Sorry but I’m not sure what you’re envisioning.
Could you explain?
