(Seattle, WA)  --  Embattled Mars Hill Church founder and pastor Mark Driscoll is stepping down.  The website for the Seattle-based mega-church says Driscoll submitted his resignation earlier this week, and it was accepted by the church's Board of Overseers.  Driscoll had been on a leave of absence for about two months, following accusations of bullying and conflict with fellow church administrators, as well as cutbacks and closures of some of its locations because of financial problems.  Mars Hill opened a church in Southeast Portland in 2011.
