I picked up a prayer card with this prayer on it when I was at St Lawrence Catholic Church in Indianapolis, Indiana.
Most merciful mother, you came to us out of your compassion when you appeared to humble Juan Diego, who called the smallest and dearest of your sons. Give us your strength and protection, especially to the poor, the young, the elderly, and the vulnerable. Plead on their behalf to the Father, that they may experience divine love tangibly in their daily lives, that all who work for justice on their behalf may grow in fortitude and humility. In these ways, manifest your charity and concern in their lives, that the cry of humanity may be heard, that all of our suffering, pain, and misfortune may be filled with divine comfort and healing. May we always know the peace of being in the cradle of your arms. Bring us safely home to your son, Jesus. AMEN.
