William had renounced the duties of inquisitor because he could no longer see it. For this reason he was unable to speak to me of that mysterious Fra Dolcino. But then, obviously (I said to myself), William has lost the assistance of the Lord, who not only teaches how to see the difference, but also invests his elect with this capacity for discrimination. Ubertino and Clare of Montefalco (who was, however, surrounded by sinners) had remained saints precisely because they knew how to discriminate. This and only this is sanctity.
