If its so bad all it takes is one letter and your name is off the rolls. Just type a letter and mail it in.
My question is, if its so bad, why don't you do that? Whats holding you back?
You don't need to be excommunicated. Thats way too complicated. You could do it so easily...but why not?
You are disgruntled about something. Why not let us in on what that something is?
I have a feeling that its not the church thats bugging you, but rather someone at church (or some cultural issue) pissed you off. Now, you are who you are because of it.
As if writing a letter would solve it all. You must be a single young man!
