St. Thomas Aquinas says: “Praise be to Jesus.”

“Please realize that every virtue must be pursued intellectually, emotionally and spiritually; otherwise it is only pretense. Forgiveness is no different. If it is pursued in the mind and with emotion, it is a beginning.”

“But the real virtue of forgiveness must be deep in the heart. In like manner, the soul must not allow unforgiveness to enter his intellect and emotions. To do so assails the forgiveness he may have accepted in his heart. This is how Satan attacks the virtuous heart.”
