Write a long, nasty, mean-spirited letter to explain everything that they dislike about the church and articulate their own self-pity at length. Dear Chairman Board of Elders,.I am writing to withdraw my membership from Grace Community Church. Got my membership withdrawal letter. 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. I joined TNPC last month; however, I still need to write the letter officially terminating my membership at my parents' Methodist Church. 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. Answer: There is no requirement in the Bible for a formal letter to be written in order to apologize for your sins.
