Christianity in Korea
Hangul, a phonemic Korean alphabet invented around 1446 by scholars in the court of Sejong the Great, was little used for several centuries because of the perceived cultural superiority of Classical Chinese (a position similar to that of Latin in Europe). However, the Catholic Church became the first Korean religious organization to officially adopt Hangul as its primary script. Bishop Siméon-François Berneux mandated that all Catholic children be taught to read it. Christian literature printed for use in Korea, including that used by the network of schools established by Christian missionaries, mostly used the Korean language and the easily learned Hangul script. This combination of factors resulted in a rise in the overall literacy rate, and enabled Christian teachings to spread beyond the elite, who mostly used Chinese. As early as the 1780s, portions of the Gospels were published in Hangul; doctrinal books such as the "Jugyo Yoji" (주교요지) appeared in the 1790s and a Catholic hymnal was printed around 1800.
Kim Tu-bong
After graduating from Bosungkobo (Bosung College) in 1908, Kim Tu-bong worked closely with a Linguistic professor from Bosungkobo named Ju Sigyeong who was at that time beginning his work in the study of Hangul for which his name would later be known for as he would dedicate his life to bring it about (the Korean script made by King Sae Jeong during the 15th century). He also worked as a teacher. In 1916 he spent a majority of his time working on compiling MalMooe, the first Korean dictionary.
