(Click to view the full-size version. Ok, so the cartoon's not specifically about UBF, but it's got a good point. I talk about someone who was abused in UBF 4 months ago and left. Then someone claims that UBF has changed so much in the last 4 months. And so it goes.)

Can Abusive Churches Change?
Those who find themselves in authoritarian churches often remain despite the difficulties because there is an underlying hope that the church can change. Even after they leave they often remain keenly interested in the affairs of the former church because they hope restoration will still occur.
Can abusive churches change? Although with God all things are possible, it is my opinion that it is highly unlikely that this will happen. Although a few have, they are the exceptions.
Why is change in these organizations so difficult? One reason is that change usually begins in the leadership. However, the leadership structure is designed so that the leader [or cabal of leaders] has control over the personnel. Although there may be a board, the individuals on the board are ultimately selected by the authoritarian leader. He selects men and women loyal to him [that cabal again], who do not question him, or hold him accountable. Therefore, he insulates himself from dealing with difficult issues or addressing his unhealthy practices.
Dysfunctional leaders also resist change because it is an admission of failure. In order for a genuine change of heart, leaders must first acknowledge a problem and repent. However, a leader who considers himself "God's man" or the spokesman for God will rarely humble himself to confess his shortcomings. Spiritual wholeness and renewal cannot be achieved until unhealthy behavior is recognized and dealt with. Unless this behavior is confronted, the likelihood of real change is diminished.
In most cases, the leadership focuses the blame on others. Those who left the church were not committed, were church hoppers, etc. Stephen Arterburn writes, "Anyone who rebels against the system must be personally attacked so people will think the problem is with the person, not the system." It is often useless to point out flaws because an abusive church lives in a world of denial. Many of the leaders are themselves deceived. Although sincere in their efforts, they may have no idea their leadership style is unhealthy and harmful. They are usually so narcissistic or so focused on some great thing they are doing for God that they don't notice the wounds they are inflicting on their followers. These leaders often twist Scripture to justify their unhealthy behavior. Most members will go along with this because they assume their pastors know the Bible better than they do.
Lastly, authoritarian churches make every effort to ensure that a good name and image is preserved. Therefore, the leadership often functions in secrecy. Disagreeing members are threatened and told to remain silent or are quietly dismissed.
For these reasons, it is my opinion that it is best to leave an abusive or unhealthy church. Learn to let go [of the hope of change] and let God deal with that group. Only He can bring people to repentance [No doubt about it]. Although painful, leaving an unhealthy church and joining a healthy body of believers will begin the healing process and open new doors of fellowship, worship, and service for you.
Add to these reasons the dynamics of Korean Confucianism in which saving face is more important than anything.
