The study shows how all the elements of Segundo's theology, his evolutionary understanding of grace and sin, his liberationist hermeneutic, his original treatment of the significance of the historical Jesus, his radically historical eschatology, converge to focus on one essential point: the works of human action that are built of love have absolute value in the eyes of God. They contribute to realization of the eschaton, where they constitute the manifestation of human freedom and the created substance of the glory of God.
