In his Life of Morrison, Townsend reminds us that the Christian Church early realized that it could not ignore so vast a nation, while its very exclusiveness attracted bold spirits. As far back as the first decade of the sixth century (505 A. D.), Nestorian monks appear to have begun a mission in China. Romance and tragedy are suggested by the few known facts regarding that early movement. Partly impelled by conviction, partly driven by persecution, those faithful souls travelled beyond the bounds of the Roman Empire, and rested not till they had made the formidable journey across burning deserts and savage mountains to the land of Sinim. That some measure of success attended their effort is probable. Indeed there are hints in the ancient records of numerous churches and of the favour of the great Emperor Tai Tsung in 635. But however zealous the Nestorians may have been for a time, it is evident that they were finally submerged in the sea of Chinese superstition. A quaint monument, discovered in 1625 at Hsi-an-fu, the capital of Shen-si, on which is inscribed an outline of the Nestorian effort from the year 630 to 781, is the only trace that remains of what must have been an interesting and perhaps a thrilling missionary enterprise. The Roman Catholic effort began in 1293, when John de Corvino succeeded in reaching Peking. Though he was elevated to an Archbishopric and reinforced by several priests, this effort, too, proved a failure and was abandoned. Two and a-half centuries of silence followed, and then in 1552, the heroic Francis Xavier set his face towards China, only to be prostrated by fever on the Island of Sancian. As he despairingly realized that he would never be able to set his foot on that still impenetrable land, he moaned: ``Oh, Rock, Rock, when wilt thou open!'' and passed away. But in 1581, another Jesuit, the learned and astute Matteo Ricci, entered Canton in the guise of a Buddhist priest. He managed to remain, and twenty years later he went to Peking in the dress of a literary gentleman. In him Roman Catholicism gained a permanent foothold in China, and although it was often fiercely persecuted and at times reduced to feebleness, it never became wholly extinct. Gradually it extended its influence until in 1672 the priests reported 300,000 baptized Chinese, including children. In the nineteenth century, the growth of the Roman Church was rapid. It is now strongly entrenched in all the provinces, and in most of the leading cities its power is great. There are twenty-seven bishops and about six hundred foreign priests. The number of communicants is variously estimated, but in 1897 the Vicar Apostolic of Che-kiang, though admitting that he could not secure accurate statistics, estimated the Roman Catholic population at 750,000.
