Of course, there would be chapels in some smaller places like towns and villages, which were generally managed by priests.
Generally speaking, as long as one performed his job well, he'd be promoted accordingly. However, in the Brilliance Shrine, it was impossible for an individual to be incompetent. No matter how well a priest did, he'd never be promoted beyond the level of a bishop if his abilities could not reach the mark. In fact, he might forever remain a priest in a chapel.
This might seem unreasonable, but it was rather fair in the Brilliance Shrine because the way that the religious professions enhanced their strength was different from others before reaching the Legendary-level. There was no need for them to meditate and accumulate mana or train their body to a certain level. They simply had to believe in their faith firmly, and their power would increase steadily.
