Who Was Saint Protasius Chŏng Kuk-bo?

Saint Protasius Chŏng Kuk-bo was a Korean lay Catholic, married, put to death at the prison in Seoul on 20 May 1839 during one of the major persecutions of Christians in the Chosŏn dynasty. He is counted among the martyrs of that persecution, part of the larger group of 103 Korean Martyrs later canonized together by Pope John Paul II. He died at about thirty-nine years of age.

Historical Setting

The setting is nineteenth-century Korea under the Chosŏn dynasty, where the Catholic faith, first brought into the country by Korean scholars who had encountered it in China rather than by foreign missionaries, was treated by the government as a foreign and subversive teaching. Several waves of severe persecution, including that of 1839, produced thousands of Korean Catholic martyrs across the century.

Why the Church Remembers Saint Protasius Chŏng Kuk-bo

The Church remembers Saint Protasius Chŏng Kuk-bo as one of the lay Korean Catholics who accepted death rather than renounce a faith that had taken root in Korea almost entirely through the efforts of Korean laypeople themselves, without resident foreign clergy for its first decades. Pope John Paul II canonized him together with 102 companion martyrs in Seoul in 1984, in recognition of the extraordinary lay foundation of the Korean Church.

Canonization and Feast Day

The record here is unusual for this corpus in that it preserves a formal date. Saint Protasius Chŏng Kuk-bo was beatified in 1925 and canonized in 1984, placing this saint among the relatively small number of Tier-2 figures whose cause was carried through the Church’s modern process of recognition rather than resting solely on ancient or immemorial local cult.

What Catholics Can Learn Today

Saint Protasius Chŏng Kuk-bo offers a lesson in the cost of discipleship: a life given up entirely rather than a faith compromised even in small ways. Few Catholics today will face that literal choice, but the underlying call — to hold nothing back from Christ — remains exactly as demanding.

A Prayer to Saint Protasius Chŏng Kuk-bo

Saint Protasius Chŏng Kuk-bo, you kept faith with Christ in circumstances now mostly hidden from us, trusting that God alone needed to see the whole of your life. Help us to be as faithful in our own hidden and unremarkable days as you were in yours. Pray for us, that we may hold firm to what we believe, gently and without fear, and that our own witness, however small it may seem, may in time bear fruit we cannot foresee. Amen.
