Religious schools? Administrated by the hierarchy, no doubt.
Theological conferences? A ruler with no wisdom or charisma won't be heard.
For myself, I've never been enamored of the Pantheonists, but for the good of the kingdom I hope this goes better than I fear if it wins. It's an unusual moment in history when a significant fraction of the playerbase is saying let's have the crown hand more official power to the Pantheonist order just because we want to; usually it requires a rebellion and a series of poor rolls (or vice versa).
We have a Charismatic father and a wise sister. We do not have to sit in the conferences ourselves.
If we are providing funding for the schools, we should have at least some say over what is taught. Even if we do not, at the very least you have to teach people how to read if you want to teach people how to read scripture.
Other reasons to vote for the Advancement of Religion Act (Or at least not vote for the calendar of festivities) are as follows.
A: If the schools start teaching some math and science, we could have an Islamic Golden Age type situation on our hands.
B: Pushing Pantheonism may help it spread into Parsia, allowing us to better assimilate our new conquest into Methianese culture.
C: It could help strengthen Methianese culture in general, which Haspen pointed out with a handy map awhile back is rather weak.
D: It could make us appear more respectable to deeply Pantheonist Cydwyl, which we are trying to woo.
E: Do you really want to give Yoe IV more reasons to party?
F: Do you really want our nobles to see Yoe IV giving himself more parties?
G: We just betrayed and invaded a large portion of our new citizens, have been tied up in several sex scandals, and our happiness is still decent. Our flow of luxury resources is all we need.
H: Even if for some reason our happiness does get low, what chance do rebels have against our army?
