How do I write a letter to change my church membership? This is an almost unanswerable question without context.Dear Chairman Board of Elders,. I am writing to withdraw my membership from Grace Community Church. This letter is my formal resignation from the Church of Jesus Christ of Latter-day Saints and it is effective immediately. Below, we'll take a look at some of the options available and two sample letters to remove a board member. I joined TNPC last month; however, I still need to write the letter officially terminating my membership at my parents' Methodist Church. "Transferring your letter" is more of a perfunctory act between churches who are merely shuffling members as though they are numbers on a score board.
