I have no problem getting into a good theological discussion with the next brother or sister, but let's call it what it really is - a disagreement or difference of opinion on theological or doctrinal issues. I believe we (in love) focus on the "major issues" and, with grace and mercy, honestly debate and discuss the non-major things of our faith. However, much on this thread has little to do with grace and mercy but more on innuendo and second-hand information (read: "gossip").
You are correct about my church using some of Warren's stuff. I have fought this for several years. Our church has never disclosed the source of this material, bolstering Warren's stated aim at being a 'stealth network' that penetrates the churches "beneath the radar".
We use less and less of this man's stuff and have abandoned much, but not all of it. I am far from satisfied that we have expunged all the false teaching that Warren's marketing organization infects churches with.
