[Objective] The religious population of the Korean Peninsula had steadily increased over the past century. However, this trend completely changed in the early 2000s, and since then, the phenomenon of de-religionization has continued. The purpose of this study is to examine what kind of religious education in colleges and universities is needed for Generation Z in South Korea in this era of de-religionization.
 [Contents] This study first provides an overview of the de-religionization phenomenon in Korea. Then, it presents an analysis of the Varkey Foundation's survey results to compare Generation Z in Korea with Generation Z interviewed in other 19 countries. Based on this analysis, the author proposes and discusses ‘spirituality education’ as the type of religious education currently needed and effective for the present generation.
 [Conclusions] This study defines spirituality as more inclusive than religiosity, and suggests that spirituality education can ultimately be a form of religious education that restores the deeper nature of religion, helping students to avoid feeling obligated or pressured to connect their religiosity to an institutionalized religion, while at the same time allowing them to rediscover their hidden religiosity and nurture it.
