There is also a large number of Catholics, though Protestants can’t see them, and they go back to the 1600s. The group of Holy Martyrs of Korea includes 103 from 1839 to 1867. Together the Presbyterians and The Catholics from before them formed the business class in Korea as the Catholics did in Japan and do in Vietnam. Christians share the Mosaic ability to trust each other and can do business with un family related others. They can make a deal and each has a reasonable expectation that the other will follow through. That is almost unique to the Judaeo Christian tradition. It is absent in almost all other cultures except Buddhists who are able to take what works from other traditions and apply it to themselves. Moslems can’t do that except as individuals in J-C societies.
As a Catholic myself, I appreciate that history! Thank you! :)
