From a Land of Martyrdom to a Festival of Youth

— Discovering Korean Catholicism Ahead of Seoul WYD 2027

 

From August 3 to 8, 2027, Seoul will host World Youth Day (WYD), the second such event ever held in Asia.

Before young people from around the world set foot on Korean soil, let us explore the 240-year story of the Catholic Church in Korea.

 

 

1. Korean Catholicism and Its Unique Character

A Church Founded by Laypeople

The Catholic Church in Korea began in 1784, when Yi Seung-hun, who was baptized Peter in Beijing, returned home.

The most distinctive feature of Korean Catholicism is that it was not first established by foreign missionaries. Instead, Korean scholars and laypeople discovered, studied, and voluntarily embraced the faith on their own.

For this reason, the Korean Church is regarded as a very rare example in world Catholic history of a Church founded through the voluntary acceptance of the faith by laypeople.

 

2. A History of Persecution and Martyrdom

One Hundred Years of Persecution and Approximately 10,000 Martyrs

Joseon society placed great importance on the Confucian social order and ancestral rites.

Catholics, however, believed that all people were equal before God and did not accept ancestral rites as religious worship.

As a result, Catholicism was regarded as an ideology that threatened the established social order.

Many believers refused to renounce their faith and sacrificed their lives.

During the late Joseon period in the nineteenth century, the Catholic Church came into conflict with the Confucian order and endured four major persecutions over approximately one hundred years.

• The Sinyu Persecution of 1801: Jeong Yak-jong, Father Zhou Wen-mo, and others were martyred.
• The Gihae Persecution of 1839: Bishop Laurent-Joseph-Marius Imbert and other foreign missionaries were martyred.
• The Byeong-o Persecution of 1846: Saint Andrew Kim Tae-gon, Korea’s first Catholic priest, was martyred.
• The Byeongin Persecution of 1866: Approximately 8,000 to 10,000 Catholics were martyred, making it the largest persecution in Korean Catholic history.

The legacy of these persecutions was honored in 1984, when Pope John Paul II canonized 103 Korean martyrs, and again in 2014, when Pope Francis beatified 124 Korean martyrs.

 

3. The Korean Catholic Church in 2026

Approaching Six Million Catholics

According to Statistics of the Catholic Church in Korea 2024, there were 5,997,654 Catholics, representing 11.4% of the total population.

The Korean Catholic Church is therefore approaching the milestone of six million faithful.

As of 2026, the Church in Korea consists of 16 dioceses, approximately 5,900 priests, and 1,789 parishes nationwide.

Strengths and Challenges

Positive Perceptions

In Korean society, Catholicism is generally viewed as a calm, rational, and socially responsible religion.

It is also positively recognized for its commitment to charitable service, human rights, and peace.

The beautiful architecture of Catholic churches, the solemnity of the liturgy, and the Church’s contributions to education and healthcare also leave a favorable impression.

 

Criticisms and Challenges

Some people, however, feel that Catholic teachings are difficult to understand and that the Mass and liturgical traditions are unfamiliar.

Others point out that the Church does not communicate sufficiently with younger generations.

There are also criticisms that the Church may appear overly cautious or authoritative when responding to certain social issues.
