“Had they ever thought of the parallel in the origins of Mohammedanism and Bolshevism—both springing out of Christianity, one proclaiming brotherhood and the other communism, but both proclaiming death and damnation upon all unbelievers. Within a century of the death of the prophet the Mohammedans had spread from Arabia to the Pyrenees by means of the sword and were stopped by Charles Martel at Tours. Russia throws up few great men but imagine what might happen if a Bolsehvik Peter the Great appeared on the scene.”

Context: Christianity is not the creed of Asia and Africa at this moment solely because the seventh century Christians of Asia and Africa had trained themselves not to fight, whereas the Moslems were trained to fight. Christianity was saved in Europe solely because the peoples of Europe fought. If the peoples of Europe in the seventh and eighth centuries, an on up to and including the seventeenth century, had not possessed a military equality with, and gradually a growing superiority over the Mohammedans who invaded Europe, Europe would at this moment be Mohammedan and the Christian religion would be exterminated. Wherever the Mohammedans have had complete sway, wherever the Christians have been unable to resist them by the sword, Christianity has ultimately disappeared. From the hammer of Charles Martel to the sword of Sobieski, Christianity owed its safety in Europe to the fact that it was able to show that it could and would fight as well as the Mohammedan aggressor...... The civilization of Europe, American and Australia exists today at all only because of the victories of civilized man over the enemies of civilization because of victories through the centuries from Charles Martel in the eighth century and those of John Sobieski in the seventeenth century. During the thousand years that included the careers of the Frankish soldier and the Polish king, the Christians of Asia and Africa proved unable to wage successful war with the Moslem conquerors; and in consequence Christianity practically vanished from the two continents; and today, nobody can find in them any "social values" whatever, in the sense in which we use the words, so far as the sphere of Mohammedan influences are concerned. There are such "social values" today in Europe, America and Australia only because during those thousand years, the Christians of Europe possessed the warlike power to do what the Christians of Asia and Africa had failed to do — that is, to beat back the Moslem invader.
