Dear Chairman Board of Elders,. I am writing to withdraw my membership from Grace Community Church.In the case of a withdrawal a simple announcement that someone has withdrawn from the church should suffice.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. I wish to bring to your attention a matter of personal significance- my decision to end my membership with our church. Letters of withdrawal are for people that perform a function outside of the congregation. So here is the question? You can always write a formal letter to your local church board stating your request and the reasons why. If they send you mail or email, you ask them to remove you from their list. Done. For Catholic parishes, it works the same.
