Perhaps… but he still remains one of my favorite authors.
“Now before I became a Christian I was under the impression that the first thing Christians had to believe was one particular theory as to what the point of [Jesus’] dying was. According to that theory God wanted to punish men for having deserted and joined the Great Rebel, but Christ volunteered to be punished instead, and so God let us off… What I came to see later on was that neither this theory nor any other is Christianity. The central Christian belief is that Christ’s death has somehow put us right with God and given us a fresh start. Theories as to how it did this are another matter. A good many different theories have been held as to how it works; what all Christians are agreed on is that is does work… You may ask what good will it be to us if we do not understand it. but that is easily answered. A man can eat his dinner without understanding exactly how food nourishes him. A man can accept what Christ has done without knowing how it works: indeed, he certainly would not know how it works until he has accepted it.
We are told that Christ was killed for us, that His death has washed out our sins, and that by dying He disabled death itself. That is the formula. That is Christianity. That is what has to be believed. Any theories we build up as to how Christ’s death did all this are, in my view, quite secondary: mere plans or diagrams to be left alone if they do not help us, and, even if they do help us, not to be confused with the thing itself.”
