'The Church claims to be the bearer of a revelation. If that claim is false then we want not to make priestesses but to abolish priests. If it is true, then we should expect to find in the Church an element which unbelievers will call irrational and which believers will call supra-rational. There ought to be something in it opaque to our reason though not contrary to it—as the facts of sex and sense on the natural level are opaque. And that is the real issue. The Church of England can remain a church only if she retains this opaque element. If we abandon that, if we retain only what can be justified by standards of prudence and convenience at the bar of enlightened common sense, then we exchange revelation for that old wraith Natural Religion.'
