It is urged that the discovery of so considerable an amount of variableness and differentiation in the Bible must be fatal to the belief in its absoluteness and infallibility. If Paul has one point of view and Peter another, then each can be at best only approximately correct. This would actually follow, if the truth did not carry in itself a multiformity of aspects. But infallibility is not inseparable from dull uniformity. The truth is inherently rich and complex, because God is so Himself. The whole contention ultimately rests on a wrong view of God’s nature and His relation to the world, a view at bottom Deistical. It conceives of God as standing outside of His own creation and therefore having to put up for the instrumentation of His revealing speech with such imperfect forms and organs as it offers Him. The didactic, dialectic mentality of Paul would thus become a hindrance for the ideal communication of the message, no less than the simple, practical, untutored mind of Peter. From the standpoint of Theism the matter shapes itself quite differently. The truth having inherently many sides, and God having access to and control of all intended organs of revelation, shaped each one of these for the precise purpose to be served. The Gospel having a precise, doctrinal structure, the doctrinally-gifted Paul was the fit organ for expressing this, because his gifts had been conferred and cultivated in advance with a view to it.
