It is impossible to know the exact number of Roman Catholics in North Korea, or to establish a worthy estimate. Estimates of the number of Roman Catholics range from 2,000 to 40,000. Christianity in North Korea is partly an underground movement, allegedly receiving missionaries from southern China. There is only one active Catholic church, called the “Changchung Church”, where a Liturgy of the Word is offered on Sunday in the capital city. However, the church is administered by the “North Korean Catholic Association,” created by the Communist government in June 1988 as a means of control over Catholic life. The remaining Catholic churches are inactive.
