Write a letter to or call the church's office and ask to withdraw membership and remove your information from their records. You can always write a formal letter to your local church board stating your request and the reasons why.Dear Chairman Board of Elders,. I am writing to withdraw my membership from Grace Community Church. 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. See Form 202 (Word 152kb, PDF 142kb). Your church must have bylaws or some other guidelines that describe the grounds for revocation of membership. I joined TNPC last month; however, I still need to write the letter officially terminating my membership at my parents' Methodist Church.
