Yes, the most commonly used passage from the seeker-sensitive group.
Paul's really only referring to two groups, the Jew and the Gentile, and his intent is that he's presenting the truth to both groups.
He is not watering down the message so as to not offend them, nor is he implementing un-biblical methods to present the gospel, and he is not sacrificing sound preaching to "win" the crowd. He is still presenting the truth of the word of God, regardless of his audience.
If you read several of Warren's quotes posted earlier on this thread, he is not doing what Paul did. Warren is mis-quoting scripture and taking things out of context in order to satisfy those who don't want to be "preached to". Many of the seeker-sensitive churches implement methods that appeal to man's fleshly desires just to "get them in the door". That is wrong. We are not accountable for making people "feel good" or meeting their "felt needs". We are taught to preach the word, in season and out of season, always being ready, regardless of who our audience is.
Two things. I am concerned when people here use the term "unbiblical methods". Second, I don't understand what one means by "watered down". If you were to take some chapters out of Galations and asked them to stand on their own, they too would appear "watered down". But they are not intended to stand alone. Like any preacher, Warrens comments that are quoted here are presented within a certain context to address a particular issue.
I am still seing no smoking gun on any major doctrinal issues. Most of it is "style" stuff.
