There is much conversation these days about the role of doctrine in the Christian life. I was recently reminded of how J. Gresham Machen addressed this issue in the context of the controversies of his day. On September 11, 1924, Machen responded to a reviewer who had published a negative review of Christianity and Liberalism in The British Weekly. Here is the essential section of Machen’s response:
[Christianity] was certainly not a way of life as distinguished from a doctrine, or way of life expressing itself in a doctrine, but it was a way of life founded upon a doctrine. It was founded more especially upon a proclamation of something that happened. The primitive Church proclaimed that happening after the first great act in it had occurred; Jesus proclaimed it by way of prophecy, but the primitive Church and Jesus were alike in proclaiming an event.
Thus, Machen insisted that Christianity is a way of life, but a way of life that is established upon a claim to truth — a claim that is essentially and irreducibly doctrinal in form and substance. The doctrine is not itself the way of life, but the way of life that is true Christianity requires an affirmation of the truth claim. Otherwise, it inevitably devolves into “a mystic experience which clothes itself in new intellectual forms in every generation.”
