Enter upon the holy days of Lent with Godly devoutness, and prepare yourselves to win God’s mercy by your own works of mercy. Quench your anger, wipe out enmities, cherish unity, and vie with one another in the offices of true humility. Rule your slaves and those who are put under you with fairness, let none of them be tortured by imprisonment or chains. Forego vengeance, forgive offenses: exchange severity for gentleness, indignation for meekness, discord for peace. Let all men find us self-restrained, peaceable, kind: that our fastings may be acceptable to God.
–Saint Leo the Great (c. 400-461)
