The following is Van Til’s response to Fred Howe’s contribution to ‘Jerusalem and Athens’.
You are certainly right in saying that I did not, in the discussion among Mr. White, Mr. Grey, and Mr. Black, make any sharp distinction between witnessing to and defending the Christian faith. I am not convinced by the evidence from Scripture which you cite that any sharp distinction between them is required or even justified. My defense of the truth of Christianity is, as I think of it, always, at the same time, a witness to Christ as the Way, the Truth, and the Life. We do not really witness to Christ adequately unless we set forth the significance of his person and work for all men and for the whole of their culture. But if we witness to him thus then men are bound to respond to him either in belief or disbelief. If they respond in disbelief they will do so by setting forth as truth some “system of reality” that is based on the presupposition of man as autonomous. I must then plead with them to accept Christ as their Savior from the sin of autonomy, and therewith, at the same time, to discover that they have been given, in Christ, the only foundation for intelligent predication.
