This has been nagging at me a little bit; I left 10 years ago, but am not DF'd as far as I know. I recognize the fact that this organization has no authority over me so would not bother with a letter just for them to clean up their records.
But to obey the Bible command, is it enough to no longer be a part of it, or is it important to show God where you stand with a formal act of withdrawal from the organization?
What are your thoughts?
