Exarch

Okay, so an exarch is a very important person in a church. They kind of act like a boss for a specific area of the church. So think of it like a big office building where there are bosses for each floor. The exarch is like the boss for a specific part of the church. They help make sure everyone in that area is following the rules of the church and they also help make important decisions about things like building new churches or choosing new leaders. Overall, the exarch helps keep everything running smoothly in their part of the church.
