The medal-crucifix of St. Benedict must be BLESSED by a priest or by a deacon. St. Benedict's medal is known to receive a blessing from priests so that it can deter the powers of evil as in storms, poisons, pestilence, legions of demons, etc. When you use this medal you call upon the intercession of St. Benedict. It has been the custom to place this medal or the miraculous medal around the house to encircle it with heavenly protection.
