The Catholic Church in North Korea founded the “Chosun Catholic Members Association” along with the completion of the Changchung Cathedral in 1988. With the Changchung Cathedral in Pyongyang and the Association thus established, they began to represent North Korean Catholics, while the Church in South Korea began a series of efforts for the sake of inter-Korean exchange and support.
Over the past 20 years, those priests and Catholics in the South who have visited North Korea through various channels had opportunities to visit Changchung Cathedral and to attend Mass together with the North Korean faithful. Humanitarian exchanges and aid have also been going on through the Changchung Cathedral. However, the reaction toward the North Korean Church varies among South Korean priests and faithful. Some of them were impressed by the liturgy in which they participated, while others have come to have suspicions. It is understandable that some would have such suspicions, asking: “Are the North Koreans who come to Mass at Changchung Cathedral true believers?”
