This research is a fulfilment of the author’s long-standing desire to furnish the Korea Baptist convention with its complete history. Particular emphasis has been given to the ideological development of the denomination from its origin in 1889 to present. It is hoped that this research will provided intellectual guidance for the convention and serve as a credible chapter in the historical and theological development of Korean Christianity especially Baptists and Pentecostals-Charismatics. Being the first attempt in compiling a comprehensive, scientific history of the denomination, this work based largely upon primary sources, many of them are unpublished. The methodology utilized by the author incorporated both documentary study and observation or interview. Accordingly, Korean documents are extensively used, while English sources comprise equally important grounds of information. Proper names have been trans-literate as closely to their original sound as possible. In pursuing the study the author has followed a strictly objective method. Any deficiency that might be found in this undertaking belongs solely to the realm of his judgment. As a foreigner the author is well aware of the lack of his rhetorical subtlety in English language. The writer hopes that this research will give a momentum for both Korea Baptist Convention and Pentecostals-Charismatics within Korean Christianity to reflect on the efforts which had been made for the expansion of Christianity in Korea, and to catch a vision for the future work, which God will reveal through his word and His Spirit.
