You can always write a formal letter to your local church board stating your request and the reasons why. I joined TNPC last month; however, I still need to write the letter officially terminating my membership at my parents' Methodist Church.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. I wanted to write you a letter of encouragement. The church membership ordinarily must be notified of the date, time, and place of both annual and special membership meetings. I wish to bring to your attention a matter of personal significance- my decision to end my membership with our church. I have given this decision careful consideration. So, please get back in the church if only out of obedience to God.
