It Is Not Right For A Servant Of God To Show A Sad And Gloomy Face

So the Father (Francis) used to censure those who went about with gloomy faces, and once rebuked a friar who appeared with a gloomy face, saying, "Why are you making an outward display of grief and sorrow for your sin? This sorrow is between God and yourself alone. So pray Him in His mercy to pardon you and restore to your soul the joy of His salvation, of which the guilt of your sins has deprived it. Always do your best to be cheerful when you are with me and the other brethren; it is not right for a servant of God to show a sad and gloomy face to his brother or anyone else."

The Servant of God Must Show Joy

If Saint Francis saw any of his companions with a sad or downcast countenance, he reproved him, saying: "If thou art grieving over thy sins, my brother, why dost thou show thy sorrow exteriorly? Let this sadness be between thee and God, and pray to him that through his mercy he may spare thee and restore to thy soul the joy of salvation, which thou hast lost through thy sins. But before me and others, show thyself always joyful, for it does not become the servant of God to manifest sadness exteriorly, nor to have a troubled countenance."

St. Francis
