“Among other things it records the coming of a missionary, Olopun, from the Empire of Ta Ts’in in 635 bringing sacred books and images, tells how the books were translated, the doctrine approved by the imperial authority and permission given to teach it publicly. It describes the spread of the doctrine, and how, later, Buddhism made more progress, but under Hiuan Tsung (713-755) a new missionary, Kiho, came and the Church was revived. The mention of the images shows what declension there had been from the original purity of the Gospel and this departure prepared the way for the triumphs of Mohammedanism that were to come.”
