Admitting God is wrong

I wasn't going to bother with Rick Warren anymore, but a couple sentences caught my eye. In a posting describing how Warren is trying to repackage himself (and failing because he is blaming others for the mess), a commentator notes:

But Warren is like many preachers I have known. He is convinced that God has called him and that this entitles him to stand above criticism. He’s become accustomed to being a leader of his flock (at 22,000 an awfully large flock) and having his word equated with Gospel.

To Rick Warren, admitting that he has done others wrong is akin to admitting that God is wrong. And why should he back down? God is on his side.

A reply then muses if Warren is acting more like a politician -- a "moderate" Evangelical -- than a pastor.
