Korean still uses 기독교도, Kidok-kyo-do for "Christian", though the Greek form Kurisudo 그리스도 has now replaced the old Sino-Korean Kidok, which refers to Christ himself.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the Korean word for Christian?
기독교도, Kidok-kyo-do
