Would you say that any one sacred book is superior to all others in the world? … I say the New Testament, after that, I should place the Koran , which in its moral teachings, is hardly more than a later edition of the New Testament. Then would follow according to my opinion the Old Testament, the Southern Buddhist Tripitaka , the Tao-te-king of Laotze , the Kings of Confucius , the Veda and the Avesta .
