You can do is to end your membership in The UMC. I joined TNPC last month; however, I still need to write the letter officially terminating my membership at my parents' Methodist Church.Write a letter to or call the church's office and ask to withdraw membership and remove your information from their records. In the sample letter, fill in your personal information. Below, we'll take a look at some of the options available and two sample letters to remove a board member. _____ Please withdraw my membership with the understanding that, at any time in the future, I may have my membership reinstated. _____ I now live in. This page includes forms you may need below. Use this sample letter to dispute mistakes on your credit report.
