The theological discourse gains relevance and authenticity as it expresses the anthropological task: it is in the human reality that God reveals Himself, and his selfcomunication happens in Jesus Christ. In Him, human reality finds sense and salvation. We reflect upon the theological anthropology of Juan Alfaro, re-discovering elements of his systematics wich helps us understand the christian conception of human person. The anthropological presumptions of his theology - the world, interpersonal relations, history and death - help explain the question made by the human person themselves as a question made by God. That interpellation comes from the openness and hope that every man carries within to find the Absolute sense. In Christ the fulfillment of grace is achieved Person of the Verb of God, in his incarnation,the hermeneutic key of the saving mistery: human reality is inserted in the relation of trinitary love which personalises and christifies man and his existence. In the filial relation between Christ and the Father, every one is personalized to a new relation of filial fraternity that manifests the sense of the human person, visible in saving solidarity: personalized in Christ to christify the world and history.
