Chapter 28 — Part III: The Decalogue — The Fifth Commandment
Section 29. Forgiveness Of Injuries Commanded — But the most important duty of all, and that which is the fullest expression of charity, and to the practice of which we should most habituate ourselves, is to pardon and forgive from the heart the injuries which we may have received from others. The Sacred Scriptures, as we have already observed, frequently admonish and exhort us to a full compliance with this duty. Not only do they pronounce blessed those who do this, but they also declare that God grants pardon to those who really fulfil this duty, while He refuses pardon to those who neglect it, or refuse to obey it.
