I have never once seen a person literally turned away at the communion rail (or by the priest or EM) at a Catholic Church. I have heard "of" it on only two occasions in my lifetime:
- Once, where LGBT demonstrators wearing Rainbow Sashes came in as a group and tried to receive Communion in a Catholic Church in (I think) Minneapolis. The demonstrators had proclaimed beforehand that the "Rainbow Sash" represented "Out and Proud" Gay, and the celebrant of the Mass (I think it was a bishop) said they could not receivce Communion unless they removed their sashes. They would not; so they were not offered the Sacrament.
- Once, when a Polish priest on loan to the Archdiocese of Washington was called on a celebrate a funeral Mass for a parishioner, whose adult daughter and her "wife" introduced themselves to the priest in the sacristy right before Mass, and said they'd be receiving. He said "Not from me,you won't." They went straight to the newspaper/radio/TV, and a big media kerfuffle ensued. Shamefully, the Archbishop of Washington didn't back him up, and he was publicly reprimanded and sent back to Poland.
Anybody remember that one?
the Bishop in the "Rainbow Sash" incident was right. The priest in the DC incident was right, and the Archbishop was wrong.
If these individuals want to go to Confession, repent their sins, and then come and receive Our Lord, fine. But if they want to treat the Holy Eucharist as a political token, a publicity hook or a fast-food snack: no.
Same for the Mafia, an abortion-promoting Senator, or any other proud, strutting public evildoer.
Begone, ye workers of iniquity.
