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. See Good and Bad Reasons for Moving Churches. Of course, we would love to talk in person about all of this. Don't go, or, letter of resignation. If its bad enough in the usa the jury will probably require the church to pay money to the member they harassed as damages. Just verbally say I'm leaving and leave. If you want to explain the just verbally tell them but you are under no obligation.
