I remember recommending a Christian book on Autism, and one brother brought it to my attention that the author had committed suicide. I had to ponder whether to continue to use the book (which I did), partly because it would be unlikely that readers would find this out, partly because it didn't change the quality of the book.
We used praying the Scripture books by Ken Boa, but found out he had later delved into contemplative prayer (which disregards the actual meaning of Scripture). We chose to announce that we had not been aware that the author had made a bad turn, but that the books we used in our effort that year were themselves solid and did not recall them. But we would not use them again.
There are many ways to disgrace the Gospel. Anywhere from Bill Hybels (who was never that solid to begin with) to James McDonald to Andy Stanley to whoever. In a sense, the amazing John Stott (in his latter years) denied the eternality of hell.
So would you remove Stott's books from your church library, or just the one that deals with hell? Would you refer to books by C.S. Lewis (who had many doctrinal issues) in a positive light?
Do you cease and desist using materials from men or women who went astray sexually? Would you use the early materials from Beth Moore and Patricia Shriver from their early days but not their latter?
You get the point. How do the baby, the bathwater, and separation meld? Messy subject, this.
Part of the confusion is about this question: "Do you endorse everything someone is or does by using his/her material?"
Another ponderable is this: "If a person really loves this individual's teaching, might he or she then be drawn to some of their other books?"
In our situation with Boa, this seemed very unlikely, and we did not want to base a decision on a remote possibility. But if ti were Gordon or James MacDonald or Andy Stanley, what might we have done? When it comes to Stott, he is rock solid on so much that I would hesitate to label him a denier of foundational truth. It is tough.
What are your thoughts and opinions?
