State Religion? Yes, the CoI is a State Religion. It's also not a coincidence that the Elders hold the Rulerships (Pre-Diocese destruction it was still multiple, the current 'Ruler' of the Diocese, since there isn't much of it left, has been pushed forward by the Elders as well) and that the Elders have a lot of influence in matters like appointments of Dukes / Government positions etc. The CoI very much controls the Realm, but it has managed to place itself in the Realm Leadership. I believe that contributes to there not being much distinction between CoI and Realm, but that's mostly due a lack of a differentiating Realm. It has also existed in Fontan with a select group of followers for a while. The CoI can be very aggressive though when it smells a chance, and the Nobles are not afraid to push their beliefs onto others. It has a list of Religions at Evil, mostly those that have interacted with the CoI in some way. If you have other beliefs, you are simply wrong in the eyes of the CoI.
To be honest, it can use a few more Nobles that just fully concentrate on the Religion solely, and they would easily make it far quickly within CoI and Ibladesh. That would help a lot, but people are busy sadly, including some Elders (I'm guilty of that as well). A while back we had someone that gave a big drive to the Religion, focusing on books and fleshing out parts here and there, and got others to join in as well, but he paused his character and the momentum was a bit lost. To be honest, CoI seems so ingrained into Ibladesh it has become part of life, like breathing.
