I have a Catholic spouse and have been going to Mass in the US for twenty two years.
As far as I can tell, this is a done deal and has been for many years.
Here’s a way to tell. Just call up random Catholic churches and ask them. You are a wealthy Protestant spouse of a Catholic unwilling to become Catholic but willing to give generously to the parish if you can receive Communion. You are looking for a new parish and are discreet. And see what they say.
