What is necessary to build grand things that last? At the parish of St. Raphael in Asunciòn (Paraguay), we wanted to make known the experience of the Reducciones, places of education founded by the Jesuits for the Guaranì people. The visit to these places, in the form of a pilgrimage with children, young adults, and families helped us to recognize that the story of the evangelization of the Paraguayan people is an experience that is still relevant today.
