Dear Chairman Board of Elders,. I am writing to withdraw my membership from Grace Community Church.Answer: There is no requirement in the Bible for a formal letter to be written in order to apologize for your sins. If it's a very formal church, they may want you to withdraw your membership in the congregation. The short answer: No. I have the intention of writing and submitting a letter to the church I was a part of that would basically entail withdrawing my membership. It was a journey to believe in the uniqueness of Christ, the Scriptures and the gospel story.
