James McGrath writes in his blog entry titled "Thank God For Blessing Us With A Fallible Bible",
Perhaps, rather than assuming that the difficulties are in the Bible to test our willingness to switch off the minds God gave us, and take a leap of faith (or of gullibility), it could be assumed instead that the difficulties are there to be taken seriously, to teach us.Isn't there great value in learning not just from those before us who got thing right, but also from those who got things wrong?
A progressive faith is not about constantly re-inventing the wheel. This is a false charge that sometimes gets leveled at progressives by theological conservatives. On the contrary, progressive religion at its best does not simply reject the past, but in fact sees the past dogmas, for right or wrong, as examples of how those who preceded us wrestled with the great questions. They gives us material to work with. Maybe the process is just as important as the final result, especially since the final result may not always have been right. We wrestle with many of the same questions today that others did before us; by seeing how others addressed these questions, we don't have to start at square one. This doesn't mean slavishly adopting everything that came before us, but it does mean that we are not alone. Instead, we stand on the shoulders of our ancestors.
If you imagine progressive faith as a creative endeavor, then perhaps it is something like the difference between painting a complete portrait strictly from the imagination versus making changes to one that was already started; or writing a novel completely from the imagination versus improving on an earlier draft. It is just easier to engage in a creative endeavor when the work has already been started; and, just as importantly, you can avoid making the same mistakes if you have studied the mistakes that those before you have made.
There is, then, value in the Bible precisely because it is flawed.
