Tim Challies has an interesting article here worth reading on "theological black holes" - i.e., unwise theological endeavors that may begin with small steps but once past the event horizon are destined for disaster.
I hear them tell me about some great new theological innovation they have discovered, or some great truth the church had been hiding from them. Or I see them gain a public profile and then their books begin to quote certain authors or hint at certain ideas. And I feel that same sense of dread. And I want to tell them that others have tried this and that it hasn’t gone well.
Others have tried to reconcile God’s knowledge and all the tragedy that happens in this world through various shades of Open Theism, but it has not gone well for them and they’ve soon smeared the very character of God. Others have been convinced that “inerrancy” is too strong a term and that we have to leave some room for minor errors or for certain cultural corrections, and before long they’ve rejected not just the inerrancy of the Bible, but also its authority. Others have become dissatisfied with hearing from God through the Bible and have demanded more; they have begun to live their lives by promptings and whisperings which they ascribe to God, and so often their lives have descended into personal and theological chaos. I see them setting up shop, thinking they are doing the right thing, but all the while they are walking into disaster.
And this is one of the reasons God places us in church communities where we are surrounded by people who are that much wiser and that much more mature than we are. He surrounds us with people who have tried things and found them wanting, or who have witnessed other people trying things and being led astray. He surrounds us with people who can speak with loving authority and experienced firmness of all of their attempts and failures, and who can guide us back to the straight path. He surrounds us with people who are wise enough to detect the first signs of wandering, and who love us enough to warn us of the consequences.
