In case anyone is interested in why I posted the link to MR's interview of Rick Warren. It was because I thought it was an interesting interview. However, on reflection I have to say that although Rick Warren claimed to believe in things like the 5 Solas. If he actually did, he wouldn't have written the Purpose Driven books.
Those books are in direct conflict with what he said in the interview.
I have to conclude then that the interview made his teaching that much more dangerous. His teaching has caused some people of Reformed persuasion to defend him.
