This study explored the lived experiences of 12 Augustinian priests as they reconciled their spiritual vocation with secular mental health approaches. Using a qualitative phenomenological design, data were gathered through semi-structured interviews and analyzed using thematic analysis. Findings revealed that priests see mental health as holistic inner integration of mind, heart, and spirit. Spirituality and psychological practices were perceived as complementary through discernment. Community life served both as support and as a strain, while cultural values, stigma, workload, and confidentiality influenced their help-seeking behaviors. Despite persistent barriers, openness toward mental health is increasing. The study proposes COR UNUM, a faith-integrated program supporting holistic, preventive, and sustainable mental health care.
