Religious identity is a specific type of identity formation. Particularly, it is the sense of group membership to a religion and the importance of this group membership as it pertains to one's self-concept. Religious identity is not necessarily the same as religiousness or religiosity. Although these three terms share a commonality, religiousness and religiosity refer to both the value of religious group membership as well as participation in religious events. Religious identity, on the other hand, refers specifically to religious group membership regardless of religious activity or participation.
