" Why does the Church cause the gospel of the Last Judgment to be read on this day?

To move us to penance, and to induce us to prepare our souls for the coming of Christ, by placing the Last Judgment before our minds. Should not the thought of this terrible judgment, when all good and all evil will be revealed, and accordingly be rewarded or punished in the presence of the whole world -should not this thought strengthen us in virtue! (First Sunday in Advent) "
