MAE has three rulers (though Cathay counts in name only), a judge and two generals (lol Cathay again), 5 dukes, and several ambassadors along with a goodly handful of barons, counts and other lords.
Again what actual baring does that have though? How many of the rulers would declare war for the religion? Arcachon is the real strength of Adgharinism, they are one of the few realms that are serious about religion. OW also has dedicated faithful that would put the religion before all other considerations.
I consider most of the MAE nobles to be like the majority of Western Christians, they may never have attended church, only have a vague knowledge of the scriptures, which they most likely gained from watching Easter and Christmas TV shows, but still will tick the Christian box on a census.
