The research conducted focuses on the relationship between eschatology and secularization, with implications in light of Jurgen Moltmann s political theology, and proposes a theological contribution from the Church in contemporary times, emphasizing the aspect of justice for greater visibility of the Kingdom of God. This thesis addresses the issue of salvation history carried out by God, in which all of human history is understood as a gift, and progress as an evolution toward the best that nature, in its entirety, can achieve. These temporal promises are embraced as an ideal of secularization. In observing realities, vicious cycles of death and cries for justice are noted. The thesis shows how the Church understands its actions over time through dialogue with society in public spheres. It also presents Moltmann s theological reflections as part of a political theology of the Cross, which seeks to strengthen the identity of Christian faith while articulating its public relevance. This establishes a dialogue with the Church s Magisterium, especially regarding the hermeneutical possibilities of the Second Vatican Council, which acknowledges the world s secular nature and the Church s solidarity with the same joys and hopes as all humanity. The research employs a bibliographic review methodology, engaging in dialogues with theologians, philosophers, and sociologists, and articulates a concept of power tied to the essential service to others, touching upon ecclesiological vision as communion and diakonia and the practical understanding of dogmatic theology.
