The dissertation entitled Happiness and Theology: traces for reconciliation seeks to justify the dialogue between theology and the desire for happiness that pierces human hearts. To do so, the research delimits, from the advent of modernity, the construction and influence of the concept of happiness in our society, verifying its possible implications in the life of the contemporary individual and the consequent rupture with religious discourse. Analyzing the relationship established between Christianity and the desire for happiness, the research discusses the influence of a certain anthropological understanding that, based on a negative perspective, determines a certain distance from the theological discourse about the possibility of a happy life and focuses on the maintenance of constant mistrust in the face of human reality. Within this discourse, the presence of an original sin interpretation that is distorted and conditioned by an underground - and dangerous - dualism becomes perceptible. To overcome this scenario of mistrust and to consolidate the traits that enable the reconciliation between the possibility of being happy and theological reflection, the dissertation reflects on the announcement of the Kingdom of God carried out by Jesus of Nazareth and its consequences for theological thought and, therefore, for human relations. Thus, the research seeks to demonstrate that the human being, constantly situated under the aegis of the infinite, discovers his/her happiness by taking the risks that arise from a relational, solidary, and fruitful existence.
