In deference to the prejudices of the Brahmins a scheme was then formulated with the approval of the Pope for organising two classes of missionaries, one for the Brahmins and another for the outcasts, but the suppression of the Jesuits in the Portuguese dominions (1756) put an end to this system. The Carmelites did good service by their efforts to reconcile the Nestorian Christians with the Church. The further progress of the Catholic Church in India was impeded by the suppression of the Jesuits, the invasion of India by the Dutch, the insistence of Portugal upon its rights of patronage over all the churches of India, the downfall of the religious spirit in Europe during the eighteenth century, and finally by the destruction during the French Revolution of the colleges and religious houses that supplied workers for the mission.

St. Francis Xavier had planned to introduce the Christian faith into the Celestial Empire, but he died almost in sight of the coast. The first missionary who made any progress in that country was another Jesuit, Father Matteo Ricci[4] (1552-1610) who arrived in China in 1582. He was a man of great ability, well versed in mathematics and in the natural sciences, and well qualified to make an excellent impression on the educated classes. He was protected by the mandarins, and respected by the Emperor, who invited him to the imperial palace at Pekin (1600). Although it was his scholarly attainments that attracted the Chinese rather than his religion, Father Ricci never failed to seize every opportunity of directing the thoughts of his pupils and admirers towards Christianity. At his death in 1610 many of the mandarins had been converted, and most of the old prejudices against the new religion had disappeared. Other Jesuits equally learned and equally prudent were ready to take his place. His successor, Father Schall, was summoned by the Emperor to Pekin, and was appointed president of the mathematical society. By his influence at court he obtained permission for his fellow-workers to open Christian churches in China, and secured the publication of various Christian books in the Chinese language. The revolution that preceded the establishment of the Manchu dynasty (1644) led to some persecution, but the trouble was only of a temporary character. On the death of Father Schall in 1666, he was succeeded by Father Verbiest who was also patronised by the court on account of his scholarly attainments. Finally in 1692 an imperial rescript was issued giving the Christian missionaries full permission to preach the gospel throughout the empire. At that period the number of converts was about twenty thousand. Two bishoprics were erected, one at Pekin and one at Nankin.

In the beginning, as the Jesuits were practically speaking the only missionaries in China, it was reserved for them as their special mission-field by Gregory XIII. (1585). But later on Clement VIII. allowed the Franciscans to go to China, and finally the country was opened to all Christian missionaries by Urban VIII. The presence of the new labourers in the vineyard was not productive of so good results as might have been expected. A fierce controversy that broke out regarding the Chinese Rites[5] principally between the Dominicans and Jesuits, did much to retard the progress of the Catholic Church in the Celestial Empire for a long period. To understand the meaning of this controversy it should be remembered that the Chinese people, deeply attached to the memory of their ancestors and to their veneration for Confucius, were accustomed to perform certain rites and ceremonies at fixed periods in memory of their departed relatives and in honour of Confucius. To prohibit these was to put an end to all hope of conversion, and to tolerate them looked like tolerating Paganism. Father Ricci decided to tolerate them, mainly on the ground that they partook more of a civil than of a religious character, that in themselves they were harmless, that the Church has been always very prudent in regard to the national and civil customs of its converts, and that with the acceptance of Christianity all danger of misunderstanding would soon disappear. Furthermore, for want of better names for the Deity Father Ricci allowed the use of Tien-tschu (Lord of Heaven), Tien and Shangti (supreme emperor), words that had been used hitherto in an idolatrous sense, but which in themselves and as explained by the Jesuit missionaries were orthodox enough. Both parties in the controversy meant well, and each could adduce very convincing arguments in favour of its own views. The Dominicans commissioned one of their number to denounce these customs to Rome as idolatrous. He submitted seventeen articles dealing with the Chinese Rites to the Inquisition, and after a long discussion a provisional condemnation was issued by Innocent X. (1645). Father Martini went to Rome to defend the Chinese Rites, and to point out the serious consequences which such a sweeping condemnation might have upon the whole future of Christianity in China. In 1656 a decision more or less favourable to the Jesuits was given by Alexander VII. The decision helped to prolong rather than to settle the controversy. A crisis was reached, however, when Maigrot, vicar-apostolic of Fu-Kien, one of the priests belonging to the Society for Foreign Missions, denounced the Chinese Rites as pure paganism, and interdicted their observance to all converts within his jurisdiction. The case was carried once more to Rome, and de Tournon was despatched as papal legate to decide the case. In 1707 he issued a decree prohibiting the Chinese Rites, incurring thereby the enmity of the Emperor, who had him thrown into prison where he died (1710). All missionaries who obeyed his orders were banished. The decision of the legate was supported by several decrees from Rome, and at last in 1742 Benedict XIV. condemned the Chinese Rites, and ordered that all missionaries to China should take an oath against further discussion of the question.

The controversy was carried on with considerable earnestness on both sides on account of the importance of the issues at stake, and was embittered considerably by political and religious disputes in Europe that had no concern either with China or the Chinese Rites. The condemnation had a disastrous effect on the missions. Nearly all the missionaries were banished from the country, and the Christians were obliged to choose between apostasy and death.

In Japan[6] St. Francis Xavier had begun the work of conversion. He left behind him two of his brethren who were joined soon by other members of the Society of Jesus, with the result that about the year 1582 there were between one hundred and two hundred thousand Catholics in the country. An embassy consisting of three of the native princes visited Rome in 1585. In many districts the local chiefs granted full liberty to the missionaries, and in a short time the number of Christians rose to three hundred thousand. Some of the authorities, alarmed by the rapid growth of foreign power in the country, began to whisper among the people that the Christian missionaries were only spies working in the interest of Spain and Portugal. A violent persecution broke out against the Christians in 1587, and lasted for several years. Notwithstanding the savagery of the Pagans and the punishments decreed against the missionaries the Jesuits weathered the storm, and fresh labourers arrived to support them in the persons of the Dominicans, the Franciscans, and the Augustinians.

But national jealousy of the foreigners, more especially of the Spanish and Portuguese, fomented as it was by the Dutch and English, led to new troubles for the Christian communities. In 1614 a royal decree was issued against the Christians, and a determined attempt was made to destroy the work of the missionaries.

Punishments of the most awful kind were inflicted on those who would not abjure the Christian faith, and many, both priests and people, were put to death. From 1614 till 1640 the persecution was carried on in a systematic and determined manner, so that by that time all the missionaries were either dead or banished, and the whole of the young communities they had formed were scattered. For years Japan remained closed against the missionaries who made various attempts to escape the vigilance of the authorities.

Whatever may be the explanation, whether it was due to the severity of the climate or to the savage character of the inhabitants, the Christian missions in Africa were not productive of much fruit. St. Vincent de Paul sent some of his community to work in the district around Tunis and in the island of Madagascar. Missionaries from Portugal made various attempts to found Christian communities along the whole western coast of Africa. In the Congo the results at first were decidedly promising. Here the work was begun by the Dominicans, who were assisted at a later period by the Capuchins, the Augustinians, and the Jesuits. Many of the inhabitants were won over to the faith, but as years passed, and as the supply of missionaries failed, much of what had been accomplished was undone, though the Capuchins still continued their efforts. In Angola the Jesuits led the way, in Upper and Lower Guinea the Jesuits and the Carmelites, in Morocco and in Egypt the Franciscans, while various religious bodies undertook the work of evangelising the Portuguese colonies in Eastern Africa.

By far the greatest triumph of the Church during this age of missionary effort was that which was achieved by the conversion of the native races in the territories occupied by Spain and Portugal in the western continent. The hope of extending the boundaries of the Church was one of the motives that induced Columbus and his supporters to undertake their voyage of discovery, as it was also one of the motives urging the rulers of Spain to increase the sphere of their jurisdiction. Hence from the very beginning great care was taken to provide for the conversion of all the natives. Priests were despatched from Spain with all the expeditions. Dominicans, Franciscans, Carmelites, Augustinians, Fathers of the Order of Our Lady of Mercy, and after the establishment of the Society of Jesus, Jesuits vied with each other in their eagerness to risk their lives in the work. Generous provision was made by the rulers of Spain for the support of the clergy and the maintenance of religion. Churches were erected, episcopal and archiepiscopal Sees were founded and endowed, colleges and monasteries were established by the various religious orders, and in the course of less than a century the Church had gained in the new world almost as much as she had lost in the old.

The Spanish rulers were not inclined to destroy or to maltreat the native races, but they were unable to supervise the greedy officials, many of whom acted savagely towards the Indians, killing hundreds of them and forcing the others to work as slaves. The hatred of the Indian races for the Spaniards made the work of the missionaries more difficult, but from the beginning the Church espoused the cause of the Indians, sought to secure protection for them against the officials, and to restrain if not to extinguish entirely the practice of enslaving the natives. Bartholomew de Las Casas[7] (1474-1566) at first a secular priest, then a Dominican, and afterwards a bishop, took a prominent part in the struggle on behalf of the natives, and though his methods were not always of the most prudent character he helped to put down some of the most glaring abuses. Charles V. was most sympathetic towards the Indians, laid down very strict rules for his subordinates, and invited the bishops to become protectors of the Indians, while Paul III. insisted strongly on the freedom of the natives and their rights as men (1537).
