I know of no DoC church that requires a tithe or ten percent or a percentage of income.  Stewardship drives are held in the fall, to faciliate a budget for the church, esp. larger city or suburban congregations, and pledges are made during October or November as part of a stewarship month.  The congregation generally has a portion of its offerings going to the regional and general church levels.

I don't ever remember being asked for a specific amount or percentage.  I do remember the pastor bringing out that one guy (or a couple of times, elderly lady) known affectionately--though secretly--by church members as 'THE HAMMER' to tell the congregation that the overall pledge level was inadequate.

I can't imagine any DoC congregation getting into guidelines, bullying tactics (though 'THE HAMMER' could possibly fit that category), etc.

My church pretty much lets households determine what they can afford to give. But when we joined, the minister told us someone from the stewardship committee would visit with us to talk about giving; the meeting never happened, though. And that was just as well -- for most of our time there, we had so little income that we could barely afford to give anything. That was one reason I gave so much of my "time and talents."
