You can always write a formal letter to your local church board stating your request and the reasons why. Dear Chairman Board of Elders,.I am writing to withdraw my membership from Grace Community Church. Letters of withdrawal are for people that perform a function outside of the congregation. So here is the question? In the case of a withdrawal a simple announcement that someone has withdrawn from the church should suffice. Keep it short and to the point. Talk to the exiting church members. If they are willing, have a conversation with those who are leaving your church. I have found some churches deny the withdrawal of membership while under church discipline.
