Jesus taught us about it, and for centuries the Church has faithfully defined and defended it. Protestants deny it even exists, while many Catholics accept but fundamentally misunderstand it. Certain saints experienced a harrowing taste of it, and from it the Holy Souls cry out night and day.
In The Biblical Basis for Purgatory, the author and apologist John Salza (Why Catholics Cannot Be Masons/i>) offers the definitive scriptural explanation of this distinctively Catholic doctrine. Building on the existence of a place of temporal punishment after death is not only a logical extension of what we know about the reality of sin and God's justice, but is also a supreme expression of God's love and mercy.
