The present study illustrates the impact of threat and authoritarianism on individuals and their respective belief systems within a Christian framework. Participants completed Altemeyer's Right-Wing Authoritarianism (RWA) Scale, the Religious Fundamentalism Scale, the Questions and Doubts about Religion Scale, and the Behavioral and Faith Scale. Participants also read a threat- or non-threat-inducing article concerning the crisis of the Catholic Church. Results showed that individuals with high RWA scores demonstrated a greater support for religious fundamentalist ideals, reported less doubts regarding their religious beliefs, and identified more strongly with their religion than did those with low RWA scores. Furthermore, participants who were exposed to threat, regardless of individual level of authoritarianism, scored higher on a measure of religious fundamentalist ideals and identified more strongly with their respective religions than those who were not exposed to a threat. Most importantly, individuals high in authoritarianism who were exposed to threat demonstrated greater support for religious fundamentalist ideals, reported fewer doubts, and more strongly identified with their religion than those individuals with high levels of authoritarianism who were in the non-threatening article condition.
