Catholicism in Japan…
On 15 August, 1549, St. Francis Xavier arrived in Japan, at the port of Kagoshima in Kiusiu, with two companions and three neophytes. By the boldness of his preaching, his sanctity, and his miracles, he renewed the marvels of the Apostolic age. He preached at Hirado, Yamaguchi, Bungo, and Funai, but he was unable to see the emperor or enter Miako (Kyoto). He set out for China on 20 November, 1551. In Japan there were then 3000 faithful, the feudal regime being favourable to evangelization. Ordinarily, when a prince was converted a portion of his subjects followed him. The celebrated Nobunaga (1565), the terrible enemy of the bonzes, was kindly disposed towards the Christians and a friend of the missionaries. When he died (1582) there were 200,000 faithful and 250 churches. The three Christian princes of Bunga, Arima, and Omura sent an embassy to Europe, which was sent out, on 20 Feb., 1582, reached Lisbon on 10 May, 1584, and Rome 23 March, 1585. The ambassadors witnessed the coronation of Sixtus V and were created knights and patricians. Hideyoshi, the successor of Nobunaga, at first favoured the Christians, but being prejudiced by the bonzes, he later believed that the missionaries were spies and proscribed the Christian religion, but refrained from slaying the Christians (1587). The missionaries hid themselves and remained, and within ten years they baptized 65,000 persons (1587-97), making a total of 300,000 faithful, and 134 religious. In 1593 three Spanish Franciscans having been sent as ambassadors by the king of Spain, they were well-received by Hideyoshi. A Spanish vessel, the “San Felipe”, having run aground within the province of Tosa, the captain was foolish enough to say that the missionaries had been sent to prepare for the conquest of the country. Thereupon Hideyoshi became afraid and angry, and on 9 December, 1596, nine religious were arrested and orders were given to draw up a list of Japanese Christians. All gladly made ready for death. On 5 February, 1597, twenty-six were crucified at Nagasaki, and died preaching and singing to the end. After the death of Hideyoshi in 1598 peace reigned for fifteen years. Christians multiplied and the Faith manifested itself in all manner of good works; 130 Jesuits, some secular priests, and about 30 religious of the orders of St. Francis, St. Dominic, and St. Augustine worked side by side. In 1609 and 1613 Dutch and English Protestants arrived who were envious of the Spanish and Portuguese Catholics. In 1613 persecution recommenced. In that year the prince of Sendai, Date Masamune, sent Asahura Roku-yemon on an embassy to Pope Paul V and the King of Spain, the Franciscan Sotelo accompanying him. In the following year (1614) the edict of destruction was published by the new master of the empire Ieyasu Tokugawa, the first shogun of that name. It was decreed that Catholicism be abolished, and this edict was renewed by Hidetada in 1616, the successor of Ieyasu. The result was horrible. In 1622 took place what was called the “great martyrdom”, fifty-two chosen Christians being martyred on the same day (2 Sept.) at Nagasaki, twenty-seven being decapitated, and the remainder being burned alive. In the following year, under Iemitsu, the persecution waxed still more furious and extended throughout the empire. The cruelty and refinement of the tortures are unparalleled even in the early history of the Church. The exact number of the victims is unknown. In 1637 the province of Azima, 37,000 Christians, driven to extremities, revolted, shut themselves up within the fortress of Shimbara, and were slain to the last one. In 1640 four Portuguese ambassadors who had gone from Macao to Nagasaki were called upon to apostatize, and when they refused they were put to death without further trial. Thirteen of their followers were sent back to Macao with this warning: “While the sun warms the earth let no Christian be so bold as to enter into Japan. Let this be known to all men. Though it were the King of Spain in person or the God of the Christians or Shaka himself [Buddha], whosoever will disobey this prohibition will pay for it with his head.” Thus Japan was closed, and remained so for two centuries, during which time the persecution did not cease. A price was set on the head of foreign and native Christians. Each year every Japanese was called upon to trample the cross under foot. Some Dutch merchants consented to separate themselves from the Christian population and allow themselves to be confined as prisoners in Nagasaki on the Island of Deshima, in order to carry on business with the Japanese. In 1642 five Jesuits embarked by stealth for Japan where they died after frightful tortures. …
