I would like to endorse Dr. Peter Masters article on John Piper and Christian Hedonism.
I have heard in the past by a few people that Dr. Peter Masters is prone to go overboard in many of his critiques.
However, if this article is any indication of "going overboard" that these people have accused him of. Then I must strongly disagree with their assessment of Dr. Masters.
I found Dr. Masters to be very fair and actually said some good things about John Piper. What I like about Dr. Masters critique he focused a lot on the Scripture passages that Piper uses to prove his points. He points out how Piper takes his own ideas to Scripture and doesn't think about the context of the passages. This of course is esogesis, rather than exegesis.
I must admit that I need to read the article again and look at the Scripture passages myself, to see for myself. However I get the feeling by what Dr. Masters wrote, that the truth should become evident when I do this.
All in all, if anyone hasn't read this article that Pilgrim made available I highly recommend that you do.
