You can always write a formal letter to your local church board stating your request and the reasons why. Thank them for ministering to you and your whole family over the years.Tell them (if true) that God used them in your life, spiritually. She had a template for a letter of church membership that explained that I had terminated my membership in good standing on the effective date. Dear Chairman Board of Elders,. I am writing to withdraw my membership from Grace Community Church. I have found some churches deny the withdrawal of membership while under church discipline. I want you to know how much you and your family have meant to me, my family and this church, that makes your letter and mine all the more painful. You are allowed to resign from a church whenever you wish to do so, no matter what your covenant, church constitution or designated church leader says. What about when someone just flat out leaves the church and requests that their membership simply be cancelled?
