About Caius of Korea
Lived 1571 – 1624 (aged 52–53). Caius of Korea was a Korean buddhist monk.
Caius of Korea (1571 in Korea – 15 November 1624 in Nagasaki, Japan) is the 128th of the 205 Catholic Martyrs of Japan beatified by Pope Pius IX on 7 July 1867, after he had canonized the Twenty-six Martyrs of Japan five years before on 8 June 1862.
The 19th century French Catholic missionary Claude-Charles Dallet wrote of him in his A history of the church in Korea, "His history proves, in a dazzling way, that God would rather make a miracle than abandon an infidel who follows the lights of his conscience, and seeks the truth with an upright and docile heart."
Biography Caius was born in Korea and was given to a Buddhist monastery by his parents. He left the monastery because he could not find the peace he wanted there and went to a mountain to live as a hermit. According to Dallet, "He withdrew into solitude to meditate with more ease on this happiness which he sought. He had as a dwelling only a cave, which he shared with a tiger, which occupied it before him. This wild animal respected its guest; it even yielded the cave to him some time after, and withdrew elsewhere."
Allured by the life of the Buddhist monks, he felt that he had found what he had been seeking for many years, and went to live in one of the most famous pagodas in Kyoto. Again he felt that he could not find the peace that he wanted there, and he became ill. During his illness, he had a dream in which he saw the pagoda ablaze. Then a "child of a charming beauty" appeared to him in his dream, comforting him,
Caius then left the temple and went back to his master, who introduced him to a Christian, who in turn introduced him to some Jesuit priests. He converted to Catholicism and was baptised immediately. While he was instructed, one of the priests showed him a tableau representing Jesus Christ, at which Caius is said to have exclaimed, "Oh! Voila! Here is who appeared to me in my cave, and who foretold all that happened to me."
On 15 November 1624, Caius was burnt at the stake with James Coici (Koichi), a Japanese Catholic, after he was arrested for harbouring missionaries.
