The Catholic Bishop Conference of Korea has published the statistics of missionaries overseas.
According to the “Korean Catholic Foreign Missionary Education Association, 647 Korean missionaries were sent to 81 countries, as of October, 2007. Among them, 42 are secular priests, and 477 are women religious. The number of missionaries increased 11-14% annually since 2005.”
Since the report of the number of laypeople was not mentioned and this report dates from Oct. 2007 it would seem that the numbers would be much higher than those reported. It is sign of maturity that the Church of Korea in gratitude for the help she has received from the foreign missionaries is now returning to give from what she has received.
