Congregations seeking to transform do not demand blind loyalty. While they appropriately oppose unfounded opposition, this does not mean they oppose the loyal opposition of the contrarian. They know they need to hear the voices of diversity because it can in the long-term be a stronger and more effective approach than shallow harmony.
Failing to listen to the contrarian can negatively impact the spirit of the congregation, the eagerness for participation, and even the financial health of the congregation. Contrarians may be right. Of course, they may also be wrong. Yet, you do not know unless you listen to them.
