The Society of Ministers in some sense is the most mundane of the three branches, consisting of ordinary priests, deacons, bishops, and cardinals who administer the ordinary rites of the church. This is the largest of the three primary groups within the church, with members across the continent serving their communities. While some members of this order wield divine magic, the vast majority do not and are simply trained in theology and community leadership.
Inside Thrane, the Society of Ministers gains special importance as the organization that provides actual governance. Each village, town, and region are governed by a priest, bishop, or archbishop respectively. Not every minister serves in a governing role in Thrane, as any given village, town, or region may have multiple ministers that share the religious duties, but only one person holds legal authority. The legal authority of a governing minister is extremely broad and can only be overruled by a higher level minister. While the vast majority of theocrats use their power wisely and judiciously, the cults of the whispering flame are always looking to recruit new members to serve Bel Shalor. Furthermore, even well-intentioned theocrats are fallible and can be deceived into maladministration and injustice.

This order includes what most people would consider standard priests. They lead services at local temples, act as community leaders, conduct research and liturgical debate, or serve in Thrane’s military. Most priests of this order are experts, but adepts and clerics make up a significant minority.
