The doctoral thesis you have under your eyes born of a walk. It is an integral part of our venture, the read of life, as a disciple of the Master of Nazareth: linked to a genuine pastoral and theological vocation. The hereof theme is inextricably linked to an intense experience as a human, Christian and professor of theology: the result of a transfiguring experience of God; a meeting with the sense of life: a walk made of leaves, waywardness, doubt, uncertainty, dark nights. Throughout this walk, a matter harasses our hearts (since first steps in the world of theology), namely one (pre)occupation against the knowledge of God; on the call theological epistemology. This question has accompanied us (and troubled) from the first steps in theological work. But if God unveiled His face, as stated in the Christian faith, how is the knowledge of God? This is a question that takes us to theological epistemology (and lato sensu, points directly to the theological epistemology). This (pre)fundamental occupation have guided and pushed our way in academic research in theology, battered heart, putting us to think. Question to which we seek an answer/proposed along this thesis. Given that the knowledge of God always is between situated men and women, entered in the historical-cultural context, socio-political, socio-economic, etc., conditions and limits us, but at the same time enables us and challenges to develop others theological concepts, now in the postmodern horizon. In this sense, we propose another theological rationality that has as its starting point the finding of crisis and decline of Reason - Reason civilization collapsed (its logocentrism, the genesis of this theo-logy). So we have searched other sources of wisdom and rationality: other sources of inspiration. The first was found a rich conception of rationality in this postmodern thought, hereinafter called sensible reason. The second source comes from the seventeenth century (the cartesian rationalism): a sensible reason (friendly) as proposed to the French Blaise Pascal; in which the mystic is in the foreground: a mystical heart-centered. The third and final source comes from the fertile humus of the Christian faith, for which we are questioned about our real condition: finitude, indicating not only a radical transience, but unveiling with absolute rawness our ontological insecurity and deep interdependence. Hence, the humility not being just a virtue, ultimately, but the result of a minimum making lucidity. In this Spirit of humility, who is living space (uterus/humus): we are generated and regenerated, and we can grow. It is the Spirit that beside the Father and the Son form a humble Love Community (kenosis) and dancer (in perichoresis). Relationship model in which the Third is included: the Spirit. We are sons and daughters of this ratio Communion, and She are oriented, which implies the possibility of developing a trinitarian intercorporeality. Making room for the inclusion of previously marginalized dimensions throughout the history of Western thought: weaving with other wires, from various skeins, a trinitarian teopo(ethics).
