Religious Savior-Centered Psychotherapy (RSCP) is an innovative, faith-based therapeutic approach that integrates religious principles with evidence-based psychological frameworks, including Positive Psychology and Quality of Life Therapy (QOLT). Rooted in the Shi’ah Islamic tradition, RSCP emphasizes the transformative role of faith in a Savior while incorporating universal concepts of meaning, resilience, and well-being, making it adaptable to diverse religious and cultural contexts that share a belief in a Savior figure. RSCP draws heavily on the concept of "active anticipation" of the Imam Mahdi (PBUH), emphasizing purposeful action and hope for a just and utopian world. Within Shi’ah Islam, anticipation is not a passive state but a dynamic process of striving toward personal and societal transformation. Narrations extol the awaiting individual's status, portraying them as divine justice agents whose hope-filled and goal-oriented actions align with religious ideals of worship and well-being. This dynamic interplay between individual transformation and societal harmony makes RSCP a comprehensive model addressing both micro-level mental health needs and macro-level cultural aspirations. This therapeutic model builds on the parallels between Islamic teachings and positive psychology principles, such as hope, goal setting, and mental well-being. RSCP leverages the psychological benefits of utopian thinking, which fosters resilience, purpose, and social connection, aligning with Frankl’s emphasis on meaning and Adler’s focus on social connectedness. Additionally, RSCP integrates aspects of Quality of Life Therapy (QOLT) to operationalize the pursuit of a "Full Life," a concept echoed in positive psychology. By prioritizing individual circumstances and emphasizing meaning-centered actions, RSCP holistically addresses emotional, psychological, and spiritual dimensions of well-being. RSCP is adaptable across different religious contexts. For example, in Christian traditions, it could center on the anticipation of the second coming of Christ (PBUH), while in other religious frameworks, similar Savior-centric beliefs could guide the therapeutic process. This approach not only aids in achieving personal fulfillment but also offers a framework for fostering broader societal harmony and justice. Moreover, RSCP has the potential to fulfill intrinsic human desires for perfection, security, justice, and unity. It should be noted that, due to the novelty of this treatment method and the need for further scientific research to provide readers with data on its validity, as well as to explore its qualitative and quantitative stages, this article focuses on its theoretical foundations. A more detailed description of its components, along with the qualitative and quantitative phases of its development, is provided in other extended articles.
