Resumen:
This paper aims to identify the itinerary of a man healed from his blindness to publicly testify to his faith in Jesus as Prophet and Son of Man (Jn 9-141), amid a climate of conflict and persecution experienced by Christians among Jews of synagogue, driven by ideologies that oppress, exclude and marginalize the human being. The first chapter focuses on the gospel according to John, highlighting its historical context, its main literary and theological characteristics, as well as the historical and social context of the Johannine community that is the origin of this gospel The second chapter studies the healing of the blind, showing how his testimony appears and the rejection of opponents who do not want to see in the text. The narrative shows how the blind man frees himself from inactive blindness and gradually opens his vision through firm and eloquent testimony to people determined to reject him, culminating in a public profession of faith in Jesus as his Lord. The threat of expulsion from the synagogue is not capable of stopping his gradual process of vision recovery. By letting himself be enlightened by Jesus, the blind man courageously faces the Pharisees' onslaughts and is not afraid to oppose their opinion, even if this will bring him a severe sanction. The healed blind person thus becomes a model for the communities. The third chapter updates the text content to the present day. It seeks to see to what extent the episode may be relevant to today's Christians living in a society increasingly fragmented by disbelief, discord, exclusion and violence.
