You can always write a formal letter to your local church board stating your request and the reasons why. (It is understood that this letter of recommendation terminates the bearer's membership in The Wesleyan Church immediately.) C. Letter of Membership Withdrawal.I wish to bring to your attention a matter of personal significance- my decision to end my membership with our church. I joined TNPC last month; however, I still need to write the letter officially terminating my membership at my parents' Methodist Church. Simple. Highly Effective!
