Saint Benedict, also known as Benedict of Nursia, was a Christian saint and the founder of the Benedictine Order. He lived in the 6th century and is considered the "Father of Western Monasticism." Benedict's teachings and rule laid the foundation for monastic life in the Western Christian tradition.

The St. Benedict Medal is a religious medal that holds significance in the Catholic Church. It features an image of St. Benedict on one side and various symbols and inscriptions on the other. The medal is imbued with a blessing against evil, and wearing or using it is believed to provide protection and spiritual defence.

Here are some elements commonly found on the St. Benedict Medal and their meanings:

1. **Cross:** The prominent feature is a cross, representing Christ's victory over sin and death.

2. **Letters:** The letters surrounding the cross are initials of Latin phrases that translate to prayers for protection. For example:

   - C.S.P.B.: Cross of the Holy Father Benedict

   - C.S.S.M.L.: The Holy Cross be my light

   - N.D.S.M.D.: Let not the dragon be my guide

   - V.R.S.: Vade Retro Satana (Begone, Satan!)

   - N.S.M.V.: Never deceive me nor suggest to me what is evil

   - S.M.Q.L.: The cup you offer is too bitter; I will not drink it.

   - I.V.B.: Drink the poison yourself.

3. **Images:** Some medals depict St. Benedict holding a cross, a representation of the power of the cross against evil forces.

The St. Benedict Medal is often worn as a pendant, attached to a rosary, or carried as a sacramental. It is believed to provide spiritual protection and ward off evil influences. Catholics often use it in times of trouble or as a daily reminder of their faith.

While the medal and its associated blessings have a long history in the Catholic Church, it's important to note that beliefs in the efficacy of sacramentals vary among individuals, and interpretations of their spiritual significance can differ.
