Pope Francis at the tomb of Don Mazzolari, archpriest of Bozzolo, the priest whose books were withdrawn from the Holy Office. The same trip on which he also pays homage to Don Milani, the Prior of Barbiana. An attentive and sincere reflection that connects Pope Francis and the unheard prophet Don Mazzolari. The sensibility of two men coming from the suburbs, who, at different moments in history, knew how to open the windows and doors of the Church to the Spirit that constantly renews and transforms it.
