How do I write a letter to change my church membership? This is an almost unanswerable question without context.I joined TNPC last month; however, I still need to write the letter officially terminating my membership at my parents' Methodist Church. _____ Please withdraw my membership with the understanding that, at any time in the future, I may have my membership reinstated. _____ I now live in. If you choose to unite with another denomination, your certified candidacy would be severed and you will lose your membership in The United Methodist Church. Please notify us in a letter or email if you wish to withdraw.
