How do I write a letter to change my church membership? This is an almost unanswerable question without context.Contact the local church where you attended or were baptized. Membership is controlled at the local level. Grants to USA nonprofit and faith-based organizations, public and private schools, government agencies, and eligible groups for community benefit projects. They would show up at my door uninvited on a fairly regular basis. Wal-Mart and Sam's Club consider it our responsibility to make a positive impact in the communities we serve.
