"Few noticed the significance of what the Professor was saying in speaking of the end of Orthodox civilization. He signified the disappearance of the only Christian civilization on earth, for, from an Orthodox viewpoint, Western humanist civilization is a sub-variety and deformation of Christianity. With its invention of murderous ideologies, industrial warfare with its killing machines, concentration camps and the Atom Bomb, Western civilization is not Christian. As the American General Omar Bradley said some sixty years ago: ‘We have grasped the mystery of the atom, but rejected the sermon on the mount’. However, the situations of both Western civilization and Orthodox civilization are somewhat different today from those described by Samuel Huntingdon fourteen years ago.
On the one hand, even those who were still then deluded can now see that Western civilization does indeed only retain Christianity as a vestige from the past. That civilization is not only Non-Christian, but through the dechristianizing ideology of humanist political correctness, it is more and more openly anti-Christian. Its residual Christian sentiment has little influence on the rest of the world. Indeed, African nations are now sending missionaries to try and wake up Darkest Europe from its profound spiritual sleep and faithless indifference."
-From an essay by Fr. Andrew Phillips.
Note: I do not agree with everything Fr. Andrew writes in his essay. His writings have over time become almost radically slavophile. That said he makes some rather compelling if strongly worded points.
