Who Was Saint Iosephus Petrus Han Wŏn-sŏ?
Han Wŏn-sŏ served as a catechist in the same district of Chungcheong-do that would, within days, also claim the teenage son of a martyred priest, part of a local Catholic community that lost several of its catechists to the Byeongin persecution within a single month.
Historical Setting
By the time the Byeongin persecution, begun in 1866 under Heungseon Daewongun, reached its worst years, it had already become the deadliest anti-Catholic campaign in Korean history, claiming thousands of believers, missionary bishops and laypeople together, nationwide.
Why the Church Remembers Saint Iosephus Petrus Han Wŏn-sŏ
The Church remembers Han Wŏn-sŏ alongside Cho Yun-ho as two catechists of the same small Jeongju community, executed at the same place within ten days of each other, a local Church that lost its lay leadership in rapid succession without ceasing to exist.
Canonization and Feast Day
Han Wŏn-sŏ’s cause reached beatification in 1968 and canonization on 6 May 1984, when Pope John Paul II, visiting Seoul, declared him a saint among the 103 Martyrs of Korea, whose shared feast, 20 September, is kept across Korea’s Catholic Church.
What Catholics Can Learn Today
A small community that loses several of its leaders within days still has to find a way to continue. Han Wŏn-sŏ’s witness, alongside Cho Yun-ho’s, is a reminder that the persecuted Korean Church absorbed devastating local losses and endured anyway.
A Prayer to Saint Iosephus Petrus Han Wŏn-sŏ
