-Experience is, admittedly, the most easily abused of the four. If we allow experience to be shallowly used as a trump card whenever a proposed doctrine makes us uncomfortable (as Wright accuses others of doing), then we might as well quit pretending that we have anything worth taking seriously. But to dismiss experience because some would abuse it is equally shallow, and equally dangerous.
Experience is the forum in which our theology becomes practical. If we never stop to evaluate the fruits of our beliefs, then we risk becoming oppressors of the worst sort. When a doctrine of ours demonstrably causes more harm than good, it is time to reevaluate what we thought to be true rather than blaming those we have harmed for their supposed failure. Without experience as a guidepost, our mandate to love others eventually devolves into an abstraction in which the needs of the people we claim to love are not truly the focus of our concern.
By listening to experience we have one final quality test to ensure that we have not veered too far off course. We allow our lives and the lives of those around us to inform our doctrines, not because we don't value the Bible, but because we value it too highly to allow it to become a symbol for oppression and injustice. We take the experiences of others into account not because truth is relative, but because truth is complex and so much larger than our finite ability to fully grasp it.
Stated in this way, I don't know for sure how far apart Wright and I really are on this issue. Since I haven't read much of his writing I hesitate to put words into his mouth. But I would hope that he recognizes the importance of stepping outside the sterile confines of the seminary before claiming to have divined God's will for those who live in the everyday world.
