Main Idea: This work proposes an original multi-level model (the "Pyramid of Faith") describing the holistic structure of Christian faith as a dynamic system. The model integrates theological (spiritual-gracious) and psychological (personal-social) aspects, presenting faith not as a static conviction, but as a living, evolving process. Aim: To present and justify a new integrative model (the "Pyramid of Faith") that describes the structure and dynamics of Christian faith for the analysis, diagnostics, and understanding of an individual's path of spiritual growth. Methods: Theoretical analysis, the modeling method, synthesis of concepts from theology (the doctrine of grace, pneumatology) and psychology (cognitive, emotional, social spheres). Results: A hierarchical model has been developed, with "Miraculous Faith" as its central element – understood as a gift of grace. The model includes fundamental dyads of beliefs (social/personal, emotional/cognitive) that form the "Cross of Faith". The model's dynamics are described by the principle of synergy (the "Pillar of Faith") and cyclicity (the "Circle of Faith"). Conclusions: The "Pyramid of Faith" model offers a holistic tool for the analysis and diagnostics of spiritual growth, integrating theological and psychological dimensions. This model has potential for application in Christian counseling and psychotherapy.
