Today, in many parts of the world, the Catholic Church commemorates the feast of Our Lady of Ransom, also known as Our Lady of Mercy or Nuestra Señora de la Merced.
The Blessed Virgin appeared in 1218 in separate visions to St. Peter Nolasco, St. Raymund of Penafort, and James, king of Aragon, asking them to found a religious order dedicated to freeing Christian captives from the barbarous Saracens or Moors, who at that time held a great part of Spain. On August 10, 1218, King James established the royal, military and religious Order of our Lady of Ransom (first known as the Order of St. Eulalia, now known as the Mercedarian Order), with the members granted the privilege of wearing his own arms on their breast. Most of the members were knights, and while the clerics recited the divine office in the commanderies, they guarded the coasts and delivered prisoners. This pious work spread everywhere and produced heroes of charity who collected alms for the ransom of Christians, and often gave themselves up in exchange for Christian prisoners.
Patronage: Barcelona, Spain; people named Clemency, Mercedes, Mercedez, Merced or Mercy.
Prayer for the Feast of Our Lady of Ransom
"O God, who by means of the most glorious Mother of Thy Son was pleased to give new children to Thy Church for the deliverance of Christ's faithful from the power of the heathen; grant, we beseech Thee, that we who love and honor her as the foundress of so great a work may, by her merits and intercession, be ourselves delivered from all sin and from the bondage of the evil one. Through the same Christ, our Lord, Amen.
