Dear Chairman Board of Elders,. I am writing to withdraw my membership from Grace Community Church.Create and write an official letter to announce your departure from a church. Download finished copies as PDFs. 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. Write a long, nasty, mean-spirited letter to explain everything that they dislike about the church and articulate their own self-pity at length. With this letter I resign my membership in the Union and in all of its affiliates. These forms are now available at the Department of City Planning's Forms page. And thus they should follow the rules of their jurisdiction. I suspect a formal resignation letter would be sufficient.
