Throughout its historical development, Islamic scholastic theology (ʿilm al-kalām) has continually faced the challenge of being reduced to a purely abstract and scholastic discourse. Although contemporary modernist approaches have underscored the imperative of religion's tangible presence, the absence of a defined methodological framework for extending theological beliefs into concrete structures has often resulted in either precipitate inferences or practical impasses. Utilizing conceptual analysis and logical reconstruction, the present study aims to provide a theoretical formulation of "social kalām" by explicating the intermediate epistemic links between doctrinal belief and institutional structures. The findings demonstrate that the transition from doctrine to institution is neither direct nor mechanically causal; rather, it requires a six-tiered analytical model comprising: (1) doctrinal explication, (2) anthropological implications, (3) normative imperatives, (4) action patterns, (5) middle-range social theories, and (6) institutional arrangements. Within this framework, the transition to a social system is facilitated through the tripartite levels of "systemic ijtihād," wherein social kalām is tasked with defining normative principles and ultimate ends, while the analysis of empirical mechanisms and institutional design necessitates the active engagement of social and policy sciences. Finally, by analytically applying the proposed model to the doctrines of divine unity (tawḥīd) and resurrection (maʿād), this study incorporates a self-critical rationality. It argues that the realization of social kalām depends on addressing and containing five fundamental challenges: reducing religion to an instrument of system-building, legitimizing structural violence, reverse secularization, reducing social kalām to social engineering, and creating an epistemic rupture between foundational principles and practical action.
