The purpose of this study was to examine the process of the rationalization of talismans and incantations, which are shamanistic acts of Donghak, and to determine their public roles. To that end, it considered the relationship between the context of the late Joseon Dynasty, when the plague was prevalent, and the talismans and incantations that Suun Choi Jewoo received through mystical experiences. It then analyzed the process through which the talismans and incantations were established as doctrines, focusing on Max Weber’s concepts of disenchantment(Entzauberung) and rationalization(Rationalisier ung). It was confirmed that the disenchantment of the talisman and incantation did not represent a loss of religiosity or dereligionization. Next, the process through which Hae-wol Choi Sihyung’s original interpretation of the talisman and incantation became the foundation of metaphysical and ethical rationality and the concept of raising God in human bodies as a result of metaphysical and ethical rationalization were addressed. Finally, it was noted that metaphysical and ethical rationalization is the process of changing into practical rationality through the reorganization of the religious body. As COVID-19 significantly impacted individuals and society, experts in various fields observed that after COVID-19, people would live different lives. In response to the question of what people should aspire to if living their lives differently than before COVID-19, experts responded that it was the public role of civil society. This study aimed to establish whether religions fulfilled their public duties by only following and practicing the COVID-19 prevention guidelines that the government ordered. Therefore, this study can serve as an impetus for people seeking public roles as religious people and citizens of a society beyond blessing-invoking and shamanistic faith, which rely on religious leaders’ charisma or seek only personal comfort.
