Duquesne University is a private Catholic institution founded by the Congregation of the Holy Spirit (Spiritans), meaning it maintains a distinct religious heritage centered on Catholic values, ethics, and community service. However, the campus environment is not overly dogmatic or restrictive for students. While theology courses and campus ministry events are readily available, participation is balanced, and the university welcomes students from a wide array of religious faiths and secular backgrounds to study in an inclusive environment.
