Previous work on religiosity and authoritarianism offers several testable hypotheses that have yet to be further assessed in a cross-cultural setting. This article examined the influences that religious orientations and doctrinal faith exercise on the development of authoritarianism, using data sets from Korea and the United States. For both Korean and American Christians, the pattern of intrinsic religion's impact boosts social conservatism and authoritarian submission/aggression, while extrinsic religion expands reverence for authority figures but diminishes the degree of endorsement of social conservatism. Quest and orthodox religiosity were inconsistent across the two comparison groups. For the Americans, quest religiosity obstructs the advance of authoritarianism, but it has little to do with Koreans' adoption of authoritarian submission/aggression. Doctrinal faith was mostly recognized as having no impact on authoritarianism, although it has a weak positive linkage with the growth of social conservatism among Korean Christians. This finding implies that the impact of quest and orthodox religiosity in Asian countries is not consistent with their influences in the United States.
