Catholic political engagement faces not only a shortage of prepared cadres but also the need for formation that integrates faith, personal integrity, and civic responsibility. Studies of political theology have tended to emphasize prophetic critique and normative principles, while research has paid limited attention to the formation of political actors grounded in personalism within local pastoral contexts. This study aimed to analyze the relevance of Jacques Maritain’s personalism to Catholic political formation and to formulate a formation model that addressed the pastoral needs of the Diocese of Bogor, Indonesia. The study employed a qualitative contextual theology approach based on Stephen B. Bevans’s synthetic model. The primary sources included Jacques Maritain’s works, Scripture, Gaudium et Spes, Fratelli Tutti, and relevant scholarly literature. An interview with the Chair of the Commission for the Lay Apostolate of the Diocese of Bogor provided supporting contextual data. The study analyzed the data through a thematic-interpretive process that brought philosophical and theological sources into dialogue with the pastoral context. The analysis identified four dimensions of political formation: personal integrity rooted in the dignity of the person, an orientation toward the common good, the integration of faith and citizenship, and sociopolitical responsibility. The synthesis of these dimensions produced a four-stage formation model: formation of the person, orientation toward the common good, integration of faith and citizenship, and actualization of sociopolitical responsibility. The study concluded that increasing participation alone could not adequately address the challenges of Catholic political engagement. Formation needed to precede and accompany political engagement so that Catholics could act as moral subjects who integrated faith with citizenship and directed political action toward the common good. The study contributed to the literature by recontextualizing Maritain’s personalism from a framework of political anthropology into a formative-pastoral framework through the conceptual trajectory of personalism–formation–citizenship–political praxis–common good. This model offered a conceptual framework for developing Catholic political formation within Indonesia’s religiously plural society and provided a foundation for future empirical testing.
