Chapter XXVII. Indulgences. There are few tenets of the Catholic Church so little understood, or so grossly misrepresented by her adversaries, as her doctrine regarding Indulgences. One of the reasons of the popular misapprehension of an Indulgence may be ascribed to the change which the meaning of that term has gradually undergone. The word Indulgence originally signified favor, remission or forgiveness. Now, it is commonly used in the sense of unlawful gratification, and of free scope to the passions. Hence, when some ignorant or prejudiced persons hear of the Church granting an Indulgence the idea of license to sin is at once presented to their minds. An Indulgence is simply a remission in whole or in part, through the superabundant merits of Jesus Christ and His saints, of the temporal punishment due to God on account of sin after the guilt and eternal punishment have been remitted. It should be borne in mind that, even after our guilt is removed, there often remains some temporal punishment to be undergone, either in this life or the next, as an expiation to Divine sanctity and justice. The Holy Scripture furnishes us with many examples of this truth. Mary, the sister of Moses, was pardoned the sin [376] which she had committed by murmuring against her brother. Nevertheless, God inflicted on her the penalty of leprosy and of seven days' separation from the people.470
