“When people write the lives of the saints, they usually write one long lie. They should write everything about them: their repugnance, their difficulties, the struggles they had to keep themselves holy, even their falls and faults. Instead, far too often they write only about their virtues, as though they were faultless and free from the effects of original sin.” – Saint Leopold of Herceg Novi
Written in 2015, this book gives short biographies of each of the saints (and a few blesseds) of the Catholic daily liturgy.
