Two studies examined mission-identity perceptions as predictors of faith maturity among students at a faith-based university. Study 1 (n = 304; 222 women, 82 men) assessed the relationships among students in the general student population. Study 2 was a replication of Study 1, but included students involved with a campus ministry organization (n = 94; 69 women, 25 men). In Study 1, innovative and inclusive mission-identity perceptions were significant, positive predictors of vertical and horizontal faith maturity. The findings of Study 2 were consistent with those of Study 1, with one exception. Specifically, no evidence of a relationship between mission-identity perceptions (innovative and inclusive) and horizontal faith maturity was found in Study 2. Results may offer insight into the factors that influence students' spiritual development at faith-based universities.
