The Latin word loríca means “a leather cuirass; a defense of any kind; a breastwork, parapet”. In effect, it means “armor”. It has come to be associated with a prayer attributed to St. Patrick (+ 5th c.) .
“Loríca” is also association with an rhythmic invocation or prayer especially for protection as when going into battle.
The Lorica of St. Patrick is rooted in an unconfused belief in the supernatural dimension of our lives, that there is a spiritual battle being waged for our souls, and in our absolute dependence on the One Three-Personed God.
One could pray this prayer each and every morning.
