Jesus taught us about it, and the Church has faithfully defined and defended it and many, even Catholics, fundamentally misunderstand it . . . Purgatory. Author, John Salza, offers the definitive scriptural explanation of this distinctively Catholic doctrine. Building on the teachings of Christ and St. Paul, this book does more than defend and explain Purgatory it provides a solid plan, drawn from the hurch’ s perennial wisdom for conquering our sins by God s grace, while still on earth.
