You can always write a formal letter to your local church board stating your request and the reasons why. Dear Chairman Board of Elders,.I am writing to withdraw my membership from Grace Community Church. To make a withdrawal from your agency fund, you must submit an authorization letter to CCF. Write a letter to or call the church's office and ask to withdraw membership and remove your information from their records. NOTE TO MEMBER: The church requires a signed request from each person requesting withdrawal. This form should be given to your pastor for processing. When any member requests a letter of withdrawal, the pastor and local church secretary shall grant it on the proper form provided in 6040. Got my membership withdrawal letter.
