A preacher must be prepared in his soul to speak the truth, both in denouncing and correcting shortcomings and in praising virtue, to such a point that he is willing in that cause even to face death - St. John of Sahagun

A contemporary, when asked about Saint John, explained: “If you ask me about the actions of Friar John, with regard to the poor and afflicted, exploited widows and children, the needy and the sick, I would have to say that he was naturally compelled to help them all in word and in deed. He was particularly interested in leading all to peace and harmony, and putting an end to hostility. Living in Salamanca, where the entire city was split into factions, he succeeded in preventing much bloodshed.”
