The Youth Movement that Brought Catholicism to Korea

Korean scholars studying the Western Learning in the late 18th century. 

The host city for World Youth Day 2027 will be Seoul, South Korea. The fact that an American Pope will be presiding and that Korean culture generally is pretty popular in the US means that interest in attending should be pretty high among Americans. I suspect that some of my own kids may find their way over there for the event. 

This being the case, what better time for American Catholics to find out about the vibrant past and hopeful future of the Church in Korea? Seoul is a particularly appropriate site for WYD 2027 considering that Catholicism had its origins in Korea largely as the result of a youth movement.

Christianity got a comparatively late start on the Korean peninsula. The first murmurings of Catholic doctrine only arrived in Korea in the 18th century. This was largely due to the closed nature of the country during the Joseon Dynasty (1392-1897). But that hasn't stopped Koreans from catching up quickly. At present, there are nearly 6 million Catholics in Korea, representing about 12% of the total population. 

Perhaps the most awe-inspiring aspect of the advent of Catholicism in Korea is that unlike practically every other country in the world, the Faith did not first arrive there courtesy of foreign missionaries. Indeed, foreigners were strictly forbidden from entering the Joseon kingdom. Though several French martyr-saints would play key roles later on, Catholicism would first emerge in Joseon based solely on the Holy Spirit-inspired intellectual curiosity of a few Korean scholars. 

Western literature began to filter into Korea in the mid-18th century, courtesy of embassies sent from the Joseon royal court to the imperial court of Qing Dynasty China. Interest in Western learning was particularly strong among the young members of noble families. Though brought up to follow the strict doctrines of neo-Confucianism which stressed right living and filial piety, these young scholars were eager to get their hands on anything related to the outside world.  

By the early 1780s, enough Western literature had reached Korea for scholars to set up study-groups to explore Western philosophy and religion. One of these scholars, a young man named Yi Seung-hun, joined an embassy to China. While in Peking, he found a French Catholic priest who instructed him in the Faith and baptized him, giving him the Christian name of Peter.

Peter Yi Seung-hun returned to Korea with a treasure trove of Catholic books, crucifixes and artifacts which he presented to his study group. These men were deeply impressed by some of the unique teachings of Catholicism, among them: that God not only exists but actually condescended to appear on Earth in the form of the man Jesus Christ; that all men possess an immortal soul; that a man's soul is destined either for eternal life of bliss in Heaven or eternal torment in Hell based on how well he follows the teachings of Christ in the Gospels.

Among the study group was a revered senior scholar named Yi Byeok who had encouraged Peter Yi to join the embassy to China in the first place. Upon reading the books brought back from China by Peter, Yi Byeok was convinced that Catholic teaching was true. He and several other members of the study group desired baptism and Peter did the honors.

What happened after that was again unique in the history of the Church. Based on their limited knowledge of Church practice, this first handful of Korean Catholics stood up their own church in imitation of the Catholic Church. This included the creation of bishops and priests, and the administration of the sacraments, including Holy Eucharist in a liturgical setting. This pseudo or improvised church endured for several years until in response to letters sent to China seeking guidance, the Korean Catholics were told that they could not celebrate the sacraments without properly ordained priests, and that priests could only be ordained by legitimate bishops.

From that point on, Korean Catholics would petition the Church to send priests and bishops to minister to them. Given that foreigners were absolutely forbidden from entering the Joseon kingdom except on official business with the court, and that any foreigners who attempted to enter without permission could be tortured and executed, it was exceedingly dangerous to attempt to smuggle a Catholic priest into the kingdom.

But what caused the new Korean Catholics the most distress was the instruction that the traditional form of Confucian ancestor worship, including the offering of food and drink to their deceased relatives, was a superstition that could not be reconciled with Catholicism. Failing to perform these rites made one unfilial and a public disgrace. For members of the upper class, the censures for such failures to revere their ancestors were more dramatic. By 1791, Korean Catholics who refused to perform the rites of ancestor worship were being condemned and executed.  

Many noble Catholics, Yi Byeok among them, refused to repudiate ancestor worship and subsequently abandoned the nascent Church. Those brave souls who remained were viewed with increasing suspicion and hostility by the Joseon court. By 1795, Catholicism was considered a subversive foreign religion disruptive to the harmony of the Joseon state, and the first larger scale persecutions of Korean Catholics erupted. 

The reigning monarch at the time was King Jeongjo, a rather high-minded ruler who tolerated a certain amount of internal dissent in the interest of national unity. The idea of kingdom-wide persecution of Korean Catholics would not fly as long as he was in power. During the reign of Jeongjo, a Chinese Catholic priest, Fr. James Zhou Wen-mo, managed to enter Joseon and it is estimated that the Catholic community in the country grew to nearly 10,000 adherents. Peter Yi Seung-hun, who had vacillated due to intense pressure from his family, remained one of the leaders of the Church at this time. Also among the leaders was a man named Alexius Hwang Sa-yeong.

Unfortunately, Jeongjo passed away in 1800. His successor was his 10 year-old son, Sunjo. This boy-king was under the thumb of his great grandmother, Grand Queen Dowager Yesun, who ruled Joseon as regent during Sunjo's minority. Yesun did not share the same scruples as Jeongjo when it came to Catholics. During her regency in 1801, the Shin-yu persecution was initiated, in part as a political maneuver to incriminate a rival faction at court that was more sympathetic to the Catholics. 

The Joseon court produced a edict entitled the Imperial Message Prohibiting the Evil Learning. In no uncertain terms, this document declared Catholic teaching to be in opposition to Confucianism, which was considered the True Learning. The followers of the Evil Learning would be forced to abandon it. As the edict itself declared:

All who disobey will be considered as rebels and guilty of high treason....[T]he head of each unit of five families shall immediately denounce any who persist in following the Evil Learning. All such persons are to receive condign punishment so as to root out the Evil Learning once and for all and to leave no trace of it remaining. [Kim & Chung: Catholic Korea: Yesterday and Today, p. 54-55].

Among the first victims of the Shin-yu persecution was Fr. Zhou who surrendered himself and was executed. Hearing about this event, Alexius Hwang Sa-yeong retreated to the mountains to escape capture. While in hiding, he composed the famous Silk Letter. Written on a sheet of silk roughly one foot by two feet, the Silk Letter was addressed to the Bishop of Peking and related the travails of the Korean Church. In 13,000 Chinese characters, the letter provided estimates of the numbers of Catholics in Korea, an account of the martyrdom of Fr. Chou and other Korean Catholics, and an appeal for help. Most critically, Alexius Hwang suggested that the Bishop enlist the help of the Qing Emperor of China and European nations to intervene with the Joseon court to protect Catholics.

The Silk Letter was never sent. Alexius Hwang was captured by Joseon government authorities and the letter was confiscated. Its contents seemed to prove the worst suspicions about Catholics. To the deeply isolationist Joseon court, the Silk Letter was incontrovertible evidence that Catholics were a subversive element who would not hesitate to appeal to foreign powers for aid against their own government. As a result, the Shin-yu persecution intensified. Alexius Hwang was found guilty of high treason, was executed and his body dismembered. His family was exiled. 

Peter Yi Seung-hun was also a victim of the Shin-yu persecution. Considered one of the leaders of the Catholic Koreans, he was arrested and tortured over the course of eight days and then executed. Since then, Peter Yi's status as a martyr or an apostate has been the subject of considerable debate. Very recently, the Korean Bishops' Conference declared him a Servant of God—the first step toward canonization.

By the time the Shin-yu Persecution subsided, the Joseon government had executed several hundred Catholics and exiled many more. It seems that a large number also apostatized. As the persecution had focused by design on educated Korean Catholics, the remnants tended to be from the poorer classes and survived in hiding in the provinces.

This would be the first of many persecutions that the young Church in Joseon would endure. This pattern of uneasy peace punctuated by periods of intense persecution was the world into which later notable Korean Catholics like Paul Jeong Ha-sang, Andrew Kim Dae-geon, Thomas Choe Yang-eop, and numerous others would soon be born. During the mid-19th century, thousands of faithful Korean Catholics would endure tremendous suffering before the age of martyrdom finally drew to a close after 1866. The victories, defeats, heroic deeds and heartbreaking betrayals of this time are brought to vivid life in Martyr of Blood, Martyr of Sweat: The Letters of Saint Andrew Kim Dae-geon and Thomas Choe Yang-eop, translated, edited, and annotated by Brothers Anthony and Han-yol of the Community of Taizé. If you'd like a good introduction to the early years of Catholicism in Korea, this collection of authentic letters by the first two native-born Korean priests is an excellent source and a very engaging read.

If you're not a big reader, some of the events related above are interwoven through the plot of the series, Yi San. This K-drama tells a romanticized but very poignant version of story of King Jeongjo in which Catholic Koreans and their status as pawns in the factional battles of the Joseon court are mentioned. The drama focuses on the early life of King Jeongjo and his romance with his favored Royal Consort. The main villain in the drama is Queen Dowager Yesun. If you have 70 hours or so to spare, I highly recommend it.
