I’m sorry that happened to you.
Many of the Sunday and Easter Masses I have seen have had musicians, cantors, and lectors - somewhere between 2 and 6 people I’d say. I know the idea is to try to put on a “nice” Mass that resembles one we would normally have on the given day, and for the most part they succeed, so that hasn’t bothered me, whether or not those people receive Communion (sometimes yes and sometimes no).
There is one church located in the heart of the urban area most hit by COVID in these parts that has seemed to have people receiving who were not playing any role in the Mass, i.e. not lectors, cantors, musicians, or altar servers, and I was grumpy over that for a day although I didn’t complain in the social media comments or write to the bishop.
In the end I decided to just take it as a lesson in humility and offer it up, because the reality is that even if they would have welcomed me at that Mass, I wasn’t going to be driving a long distance into an area with 10 times more COVID than my local area to attend it, and for all I know maybe those people really needed the special grace of that Eucharist. It was not easy to keep from feeling resentful about it though. I always have to fight the feeling that the parishes act like “every parishioner is special, but some are more special than others.”
