The church of the City of the Clouds is the biggest church you can find in the Luminous Continent. Comparing all the churches present in the continent, this city has the biggest one and you can say that this is as big as the most well-known historical churches in the world. That's how big it is and it's not just a big place for a mass to take.
After the events of the expedition in the past life where the Anti-Rebellion won, the church flourished, its teachings spread out, and the pope gained the title of "Saint" and is one of the figures that governs the people of the continent. You can say that he is the so-called "President" of the Luminous Continent and due to that, his presence and name spread out to every part of the world.
