“Right now, we are officially banned from marriage and ordination, and often denied other sacraments, as well.” - Yes, and you should be.
Actually, a person who is attracted to have sex with someone of the same gender is still allowed to marry a person of the opposite sex. I’m pretty sure that given the history of the bunch of queens who were in the seminaries in the 70s and the havoc they wrecked that the seminaries are being very careful who they allow in now but having an attraction is not the same as somehow you’re born a certain way. I’m trying to change my speech and my granddaughter’s speech so that I don’t speak of “gay” people but of people who are sexually attracted to someone of the same sex. We all need to do that. Once we lost that narrative, it became a civil rights issue which it totally is not.
The Sacrament they need most, right now, is Reconciliation (also known as Confession.) Once you repent and turn away from your sins, you’re good to go as far as the other Sacraments. Including Matrimony: if they can find somebody of the opposite sex to marry.
