Le Pelerinage de Lourdes §35

³⁵ In a society which is barely conscious of the ills which assail it, which conceals its miseries and injustices beneath a prosperous, glittering, and trouble-free exterior, the Immaculate Virgin, whom sin has never touched, manifests herself to an innocent child. With a mother's compassion she looks upon this world redeemed by her Son's blood, where sin accomplishes so much ruin daily, and three times makes her urgent appeal: "Penance, penance, penance!" She even appeals for outward expressions: "Go kiss the earth in penance for sinners." And to this gesture must be added a prayer: "Pray to God for sinners."
