The stories of the several Protestant groups vary much; from what I know, their motives and behaviors I don't share, though there is much to admire in them and in their followers; RCs can learn much from them. As for Sedevacantists, and the SSPX crowd, I see nothing admirable in them. But it's not my business.

The first four councils, up to Chalcedon, were truly ecumenical and are definitive for faith (and say NOthing about sexuality). Trent and Vat I work for decent order, but reflect the RC fearful weakness in imposing uniformity. The much better new outlook of Vat II should have been allowed to flourish, but JPII and the conservatives ended that project too fast.

The magisterium should be consulted as one source of wisdom alongside others. Obedience is a virtue only when one is persuaded the authority deserves being obeyed. "Hard sayings" should be hard for everybody, but Christians with anti-gay bias find it too easy to flaunt those few gay-unfriendly texts in Scripture.
