Yeah, it's tied to control of holy sites. There are two ways to do it: one way only requires 3 of the 5 holy sites, but also requires the faith to have a Moral Authority of 50, which might not be feasible. The second way requires control of all holy sites but doesn't have an MA requirement. Both ways also require 750 piety.

There are other ways to get Moral Authority, of course: raiding infidel temples, successful county conquests, paragons of virtue, building temples, certain festivals and successful county conversions all increase it slightly. You can now also build a "Great Pillar" for a cool 5% MA. Conversion rate is affected greatly by the moral authority of the religions involved, but unreformed religions are penalized, as noted.

Speaking of reforming, I'm using a mod that lets you pick 3 doctrines instead of the two, and I did successfully reform Romuva. Unyielding/Defenders of Dievas/Astrology/Stable. I don't really power-game, but the Kingdom of Lithuania will be well-insulated from threats, from within and without.
A note on natures: I've read that they made a mistake insofar as the chances the AI will attempt to convert a county. Only Unyielding and Proselytizing have proper weights: the rest have none, meaning the AI will basically never try to convert anything if you select other Natures. It does sound like they have a bug-fixing patch in the oven though, so hopefully it's fixed soon.
