“…but out of the desert, from the dry places and the dreadful suns, come the cruel children of the lonely God; the real Unitarians who with scimitar in hand have laid waste the world. For it is not well for God to be alone.” -- from Chesterton's wonderful book, Orthodoxy, a book every human being should read. It was written 108 years ago, in 1908.
“There is in Islam a paradox which is perhaps a permanent menace. The great creed born in the desert creates a kind of ecstasy out of the very emptiness of its own land, and even, one may say, out of the emptiness of its own theology. It affirms, with no little sublimity, something that is not merely the singleness but rather the solitude of God. There is the same extreme simplification in the solitary figure of the Prophet; and yet this isolation perpetually reacts into its own opposite. A void is made in the heart of Islam which has to be filled up again and again by a mere repetition of the revolution that founded it. There are no sacraments; the only thing that can happen is a sort of apocalypse, as unique as the end of the world; so the apocalypse can only be repeated and the world end again and again. There are no priests; and yet this equality can only breed a multitude of lawless prophets almost as numerous as priests. The very dogma that there is only one Mahomet produces an endless procession of Mahomets. Of these the mightiest in modern times were the man whose name was Ahmed, and whose more famous title was the Mahdi; and his more ferocious successor Abdullahi, who was generally known as the Khalifa. These great fanatics, or great creators of fanaticism, succeeded in making a militarism almost as famous and formidable as that of the Turkish Empire on whose frontiers it hovered, and in spreading a reign of terror such as can seldom be organised except by civilisation…” -- from Chesterton's brief book, really a eulogy, on Lord Kitchener (1917).
“When people talk as if the Crusades were nothing more than an aggressive raid against Islam, they seem to forget in the strangest way that Islam itself was only an aggressive raid against the old and ordered civilization in these parts. I do not say it in mere hostility to the religion of Mahomet; I am fully conscious of many values and virtues in it; but certainly it was Islam that was the invasion and Christendom that was the thing invaded." -- from Chesterton's book, The New Jerusalem (1920)The above comments make one wonder what Chesterton would have thought of Islam today, particularly those expressions of Islam that manifest themselves as ISIS, al-Qaeda, Hamas, Hezbollah, et al.
