Based on the concepts of Pargament's adaptational functions of religiosity, Huber's centrality of religiosity, and Block's conceptualisation of ego-resiliency as psychosocial resources, a nonexperimental, moderated mediation project was designed for a group of 175 women and 57 men who voluntarily participated in an online study to determine whether and to what extent religiosity mediated or moderated the relationship between ego-resiliency and the severity of PTSD and depression during the COVID-19 epidemic. The analyses carried out showed that the studied variables, ego-resiliency and centrality of religiosity, were predictors of the intensity of some psychopathological reactions caused by the COVID-19 pandemic but were not connected via a mediation relationship. Therefore, one question remains open: what is the role of ego-resiliency and the nature of the stated immunogenic effect of the centrality of religiosity in dealing with the critical threat to mental health that is the COVID-19 pandemic?
