People have fallen into a foolish habit of speaking of orthodoxy as something heavy, humdrum, and safe. There never was anything so perilous or so exciting as orthodoxy…It was the equilibrium of a man behind madly rushing horses, seeming to stoop this way and to sway that, yet in every attitude having the grace of statuary and the accuracy of arithmetic. The Church in its early days went fierce and fast with any warhorse; yet it is utterly unhistoric to say that she merely went mad along one idea, like a vulgar fanaticism. She swerved to left and right, so exactly as to avoid enormous obstacles…To have fallen into any of these open traps of error and exaggeration, which fashion after fashion and sect after sect set along the historic path of Christendom – that would indeed have been simple. It is always simple to fall; there are an infinity of angles at which one falls, only one at which one stands. To have fallen into any one of the fads from Gnosticism to Christian Science would indeed have been obvious and tame. But to have avoided them all has been one whirling adventure; and to my vision the heavenly chariot flies thundering through the ages, the dull heresies sprawling and prostrate, the wild truth reeling but erect.
