The purpose of this study was to look at the devaluation of Christianity and its alienation from the people and ask, “What is the meaning of Christianity being introduced into Korean society, and what impact has it had?”. In the process of accepting Christianity, the analysis focused on political and social situations, economic and religious situations as acceptance factors. Politically and socially, the pressure for reform and opening by Western powers, the signing of treaties, and the introduction of new systems were analyzed. In terms of the economic situation, the economic impoverishment suffered by the people of countries that failed to adapt to world historical changes and quickly accept the culture of modernization explained. In addition, referring to the suppression of Catholicism in the process of introducing Catholicism and the failure of the Catholic introduction process in the religious situation, various methods were tried and the situations in which the gospel was gradually spread were explained. It was pointed out that Christianity had a great influence on the modernization of Korea during the Enlightenment period, including the spirit of patriotism and love for the people, prohibition of discrimination between people and books, and the abolition of the caste system. In addition, the fundamental reason for the acceptance of Christianity was that it was recognized as a powerful religion that made wealth possible, and thus the gospel expanded from the powerless ruled class to the ruling class. Meanwhile, Christianity had a great influence on the March 1st Independence Movement, and the changes in the consciousness of the Joseon people due to Christian missions were examined through the establishment of independence association branches, differences in active participation, and a confession written by a nobleman. In addition, we looked into the teachings of Christianity, focusing on the subject of the independence movement, the purpose of the movement, and the methods of action in the independence movement as shown in the Declaration of Independence, and the relationship between Christianity and the role of the March 1st Movement and Christian schools. Lastly, it concludes that in the face of the decline of Christianity, which had a great influence during the turbulent times of Korean history, the Korean people need to know and learn about history.
