By Ven. Louis of Granada, O.P.
This is probably the most famous book of the favorite writer of St. Teresa of Avila, St. John of the Cross, St. Vincent de Paul, etc., etc. St. Teresa of Avila credited this book with having converted over a million people in her time. This is the most persuasive book we know to encourage people to abandon sin and embrace repentance and virtue. The logic is relentless and effective. For mastery of subject, command of Scripture and total impact on the reader, no book surpasses The Sinner's Guide!!!
