I think you're underestimating the level of acculturalisation that comes from being born and raised into a church and having your identity to a large extent shaped by it. By twenty-five, thirty, perhaps, you'd have enough of a sense of yourself to be able to stand up and say "Now, wait - I know for the first fifteen years, you told me <insert sin here> was evil, but I'm beginning to see it differently. And I don't think that makes me a lesser person." But indoctrination can be hard to shake off, and in the case, for instance, of a child who knows herself to be gay and is taught that homosexuality is evil - and whose family are probably also deeply entrenched in the dogmas - well, I think it's a difficult ask. I think the first defense should be found in the culture that she was born into. Her time for creating or finding a new culture will be some years away.
No, not at all. I completely understand it. But my point remains, it is more reasonable to ask someone to leave a club built on certain tenants than it is to ask the club to change their founding philosophies.
Obviously it's difficult and won't happen in most instances (which is why I think children should be raised outside of he church and introduced when they're old enough to decide whether or not to be involved, but that's another argument for another day.) But you must understand the issue with simply changing dogma every time a societal shift occurs? It's a religion, not a political party.
And I for one wouldn't want to make those years any harder for her. I'd like to take every chance I could to strengthen her bonds and faith in herself and in the love of the people around her. I'd feel that was my first duty, as a priest or a teacher or parent.
A teacher or parent, maybe. But surely a priest has more of a duty to uphold the tenants of his religion than he does to make individuals feel all warm and fuzzy about going against them?
