a large number of people receiving the Eucharist at Sunday Mass are probably not worthy to receive it. That's why we ask God to come under our roof and forgive us.....you will seldom see someone who is publically known to be ineligible to recieve the Sacrament doing so.....just not that common. However, if your Democrat mayor, representative, Governor....whatever is a member of your parish, I would feel free to question them personally about their position.
In other parts of the world, people refrain from Communion if they believe themselves to be in a state of mortal sin. When I was in Poland, a very large portion of the assembled did so.
It’s really a failure of catechesis in our country, which starts at the top with the bishops.
