In Sin Revisited, Solange Hertz tackles the topic of sin with a unique perspective for modern times, delving into the intellectual approaches of the Desert Fathers as well as St. John of the Cross. In Hertz's own words: "Don't expect to find the seven deadly sources so familiar in song and story. You'll find eight, and even these won't be in the same sequence most of us are used to. This approach is newer than Vatican II, because it's so much older, if you know what I mean, very much older certainly than the old Baltimore Catechism." Upon reading this book, a person may subtly undergo an examination of conscience pertaining to each sin that is being discussed. This book is designed to be a guide for spiritual perfection.
