This is an interesting article from Archie Poulos on how to leave a church well.

While this article deals with HOW to leave well as opposed to WHY to leave Archie raises some interesting questions

So I have begun quizzing people about why they leave churches. My conversations have raised two questions.
1. What issues are important enough to leave a church over?
2. What is the best way to deal with unhappiness about a church you are leaving?

I have been thinking a lot lately about what is worth leaving church over. I think the biggest cause of discontent in church is summed up well in this line –

Again, not always, but often the reasons distil down to the fact that we have absorbed the spirit of our age, where we relate to church as consumers not contributors.

I have seen this time and time again, where church becomes about what I can get out of it rather than what I can give. Church is a place of service. Christ, who is the head of the church, himself came not to be served but to serve. So if you are discontent with church I would first make sure you are not asking yourself ‘what am I getting out of this’ but rather asking ‘what am I putting into this’.
