G. K. Chesterton on Heresy

“Truths turn into dogmas the instant that they are disputed. Thus every man who utters a doubt defines a religion.”

“The word "heresy" not only means no longer being wrong; it practically means being clear-headed and courageous. The word "orthodoxy" not only no longer means being right; it practically means being wrong. All this can mean one thing, and one thing only. It means that people care less for whether they are philosophically right.”

“It is easy to be a madman: it is easy to be a heretic. It is always easy to let the age have its head; the difficult thing is to keep one's own. It is always easy to be a modernist; as it is easy to be a snob. 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 in my vision the heavenly chariot flies thundering through the ages, the dull heresies sprawling and prostrate, the wild truth reeling but erect.”
