Did she go up and receive communion? I haven't heard, one way or another.
It would be very difficult to tell anyone they couldn't attend Mass. Even if they were in a state of mortal sin or excommunication, as long as they steered clear of communion.
John Kerry made a photo-op of receiving communion, which was particularly egregious. But you can't very well stop someone from entering a church.
But the priest can deny the person communion.
I am suprised if she did it didnt melt her tounge off.
