Chapter 39 — Part IV: Prayer — The Fifth Petition: Forgive Us Our Trespasses as We Forgive Those Who Trespass Against Us

Section 2. This Petition contains a sort of summary of those benefits with which the human race has been enriched through Jesus Christ. This Isaias taught when he said: The iniquity of the house of Jacob shall be forgiven; and this is all the fruit, that the sin thereof should be taken away. David also shows this, proclaiming those blessed who could partake of that salutary fruit: Blessed are they whose iniquities are forgiven.
