Devotional medals: Saint Benedict, the Miraculous Medal and the Agnus Dei
A history of Catholic devotional medals: the letters on the cross of Saint Benedict, the Miraculous Medal of 1830, the Agnus Dei and the line with amulets.
In the Catholic world devotional medals are familiar objects, hung around the neck, sewn into linings, fixed above doors. The Church regards them as sacramentals, signs that dispose the faithful to prayer, and not as talismans with a power of their own. Their history, however, is often entwined with that of popular protection, and some of them have a curious origin, linked to manuscripts, trials and visions.
The cross of Saint Benedict and the Metten manuscript
The medal of Saint Benedict is the richest in inscriptions. On the reverse, around a cross, run initial letters which, when expanded, form short Latin verses. The best known reads “Vade retro Satana, numquam suade mihi vana”, that is, “begone, Satan, never suggest vain things to me”. Along the arms of the cross other invocations can be read, such as “Crux sacra sit mihi lux”, may the holy cross be my light.
The meaning of the letters had been forgotten. According to the traditional account, in 1647, during a witchcraft trial in Bavaria, some of the accused declared that they had been unable to harm the abbey of Metten because it was protected by crosses bearing mysterious letters. The monks found those letters painted in the abbey and discovered their explanation in an illustrated manuscript in their library dating from the early fifteenth century. Pope Benedict XIV officially approved the medal in 1742. In 1880, for the fourteenth centenary of the saint's birth, the abbey of Montecassino promoted the so-called jubilee medal, still the most widespread design today.
The Miraculous Medal of the rue du Bac
Another famous medal arose from a visionary experience. In 1830, in the chapel of the Daughters of Charity in the rue du Bac in Paris, the novice Catherine Labouré reported that she had seen the Virgin, who asked her to have a medal struck. The first medals were struck in 1832, and they spread very quickly, helped by accounts of graces received during the cholera epidemic of those years.
The image shows Mary with open hands from which rays stream, surrounded by an invocation in French to Mary conceived without sin. On the reverse are the letter M surmounted by a cross, the hearts of Jesus and Mary and twelve stars. The popular name of “Miraculous Medal” took hold before any official recognition, and bears witness to the trust of the faithful.
The Agnus Dei and the boundary with superstition
Among the oldest devotional objects are the Agnus Dei, wax discs impressed with the paschal lamb, originally made from the Easter candles and blessed by the pope, by tradition in the first year of his pontificate and then every seven years. They were highly sought after and kept in precious cases. Tradition credited them with protection from storms, fires and the dangers of childbirth.
Precisely because of this closeness to amulets, theologians and bishops often stepped in to recall the difference. According to Catholic doctrine, the value of a sacramental depends on the prayer of the Church and the disposition of the person using it, not on the object itself. Treating it as a tool with an automatic effect means falling into superstition, which the catechisms explicitly condemn.
Devotional medals show how thin the line between faith and the desire for protection can be in everyday practice. Official history places them within the liturgy, while popular practice has often treated them as talismans. Studying them allows us to observe at close range the dialogue between religious institutions and the sensibility of the faithful, a dialogue that continues to this day.
