But I’ve never seen anything like that at Mass.
When someone is a public sinner, in a matter that is potentially mortally sinful (all three conditions met), it does indeed create scandal for them to receive communion. If two men, or two women, are known to be living together, seen in public making displays of affection appropriate to married people, possibly even wearing a sign of their commitment to one another (such as rings), yes, it’s reasonable to assume that they go home and have sex, just as it is for two married heterosexual people in the same circumstances. Gay sex is an abomination — sodomy — that can never be made into a good thing.
I love gay people, there are gay people I think the world of, I do not hesitate to defend their civil rights (housing, employment, freedom from bullying and harassment, and so on), I abhor violence against them — what did they ever do to
you? — but I cannot say that sodomy is ever good. I can’t say that fornication, adultery, contraception, deliberate sterilization, or deviant sex between heterosexuals is ever good either. But we cannot automatically say that anyone is ever practicing contraception or sterilization (as has been discussed in these forums many,
many times), whereas we
can say that two gay people living as “husband and husband”, or “wife and wife”, at least if they are young, energetic, and visibly affectionate to each other, are almost certainly practicing
peccatum illud horribile inter christianos non nominandum (unless it is a case of “lesbian bed death”, which possibly has an equivalent among elderly gay men as well).
I know we all bend over backwards anymore to think the best of everyone, not to judge, not to jump to conclusions, to give everyone the benefit of the doubt, and so on —
not least because the world does not like what we believe (just tell it like it is) — but the fact remains, if someone is organizing their life so that it can be reasonably inferred that they are committing sin X, a sin that is mortal given the three conditions, and that they are not breaking with sin X, it does give scandal, and it does give scandal for them to receive communion. I don’t see much of a way around that, unless we want to suspend disbelief under the rubric of “we cannot say for sure and we cannot judge”.
