‘Blessed are the merciful, for God shall have mercy on them [Mt 5:7].’ Remember, Christian, the surpassing worth of the wisdom that is yours. Bear in mind the kind of school in which you are to learn your skills, the rewards to which you are called. Mercy itself wishes you to be merciful, righteousness itself wishes you to be righteous, so that the Creator may shine forth in his creature, and the image of God be reflected in the mirror of the human heart as it imitates his qualities. The faith of those who live their faith is a serene faith. What you long for will be given you; what you love will be yours for ever.
-Pope St Leo the Great-
