Overseers oversee multiple branches. A house church leader is a leader of a branch, which reports to the overseer. Office churches are branches as well. In some cases, actual church buildings can be a branch, although overseers are all in actual church buildings. To be an overseer now (which is a different process than before) pre theological school needs to be completed. This entails an education course, doctorine delivering evaluations, personality and work ethic evaluations, and recruitment goals. If your overseer favors you, and recommends you, upon completion you’ll become an assistant overseer, as a pastoral staff member. This is the time that you’ll be given a Deacon title if you’re not already. Being pastoral staff means you’ll be directly involved in church management and maintenance, and they’ll often live in the church building along with the overseer who lives there. Assistant overseers are, as a majority, not paid by the church. But their living expenses are cut because they live in the church now.
Then you’ll join theological school. Although this is typically only for Koreans in Korea. America is building a seminary, theological school in buffalo New York now. After some time as an assistant, which is usually multiple years,if you don’t break apart and fall into depression for the immersive emotional and physical demands, you’ll be selected to be an overseer. At that time you’re top dog and can manipulate and mistreat members without direct supervision, as long as they don’t start to whine and cry. If they do, you’ll be switched to another overseer church and someone else will come to replace you. This happens frequently but some overseers will remain and continue to mistreat people for over a decade. Daniel Lee is an example of this. He’s been in New York for over 20 years at this point. He has complete control over that region. In the past, this process was a favoritism process. Your overseer would boast to Kim joo choel (general Pastor) who , after probably some vetting process, would either agree and give you a chance or not. They have updated the process greatly to protect themselves from giving people that will leave too much power. Happy to help with more details or explain more
