Communion is a Sacrament, and Catholics know when they are, and are not allowed to recieve Communion. It is not the same as other churches where anyone in attendance, may recieve Communion. The priest told the attendees who was allowed to recieve Communion, and anyone Catholic knows what it means, being in a "state of Grace", or having to have your Confession herd first. I have no idea how the priest made this deduction, other than in the funeral arrangments with him, certain personal facts were made known to him, such as her being an active Lesbian living with another woman. She also made a eulogy, which I read about elsewhere, where the priest stepped away from the alter, so she may have revieled many details, that gave the priest no choice but to deny her Communion. I think there are some unsaid details to this story, that will reviel the Priest had some knowledge to have withheld Communion. Had any other Mortal sins been revieled somehow to the Priest, they also would not be considered not in a "State of Grace". To those who know nothing about the Catholic religion, and rules of Confession and Communion, they regard this as some homophobic or anti gay issue afront. Its about any kind of sin, that removes you from a State of Grace, requiring your Confession before recieving Communion again. Catholics know this. Homosexuality is considered one of those sins removing you from Grace. So is Adultry. So is being married outside the Catholic Church if you are Catholic. Catholics know this and should not be surprized about it.
