According to this article, U.S. politician Nancy Pelosi has continued to receive communion in another diocese despite being forbidden from doing so in her own diocese by her Archbishop. Is this allowed by the Catholic Church? I.e., if you get barred from receiving communion by your Bishop, you can just head over to the next diocese and continue receiving communion? What are the consequences of doing so as far as the Church is concerned?
As Andreas Blass noted, the consequences don't so much depend on what her (or anyone's) bishop said, as it does the moral and ecclesiastical law she violated (and does violate). There's layers to this.
This is evidenced by what the Archbishop wrote being "Notification". The reality pointed to (really the important thing here) by the notification existed prior to it being announced.
That reality is that Nancy Pelosi is a public person, obstinately remaining in a state of manifest grave sin. This not only concerns her, but every priest, bishop, or whoever might be in a position to give her Holy Communion, who, within reason, would recognize her.
Now, abortion is gravely sinful, and thus so is being an accessory to an abortion. Politicians who push for more abortions are accessory to many abortions. If it were a question of a private individual and their own sins, they could not go receive communion until being absolved in confession, else that communion would be an additional grave sin, "and the last state of that man in made worse than the first." But though this would be the case, Canon 915 would still not be applicable.
Because Canon 915 does apply here, the consequences are threefold that I can see.
- Those ministers who knowingly give her communion incur guilt for allowing a mortal sin that they could have, and should have stopped.
- The general public is scandalized, and also generally thrown into confusion by a lack of consistency from the college of bishops, who now appear disunified.
- Finally, the consequences of Nancy's actions, insofar as they were willed or should have been foreseeable, are imputed to her.
At the end of our lives we are all called to give an account to the Just Judge. In this case it is no different.
