If they are not engaging in sexual relations, I respect their purity.
If they are engaging in sexual relations, they are engaging in an objectively immoral act. Whether they know it or not. (A lot are confused about this.)
Very much like longtime straight fornicators who are "faithful". A lot of confusion here, too.
It's becoming common. In very many of our families, our daughters, nephews, sons, cousins, if the overall statistics can be believed.
Though common, it's still disordered, and those involved in it should be called to repentance. We hope and pray for that.
I have actusally met, though, a used-to-be-actively-gay couple who decided not to have sex. I think their choice is virtuous and honorable, because abstinence can be quite difficult and is certainly countercultural at this point, yet it is what God's law requires of everyone except lawfully wedded husbands and wives.
If I may ask, pray for all these sruggling people.
By moral, I meant the customary definition. Honest in business, kind to puppies and faithful to one’s partner.
