3. The breastplate hymn
In addition to his evangelism of the Irish and holding official church office, Saint Patrick is credited with having written a poem.
It was titled "The Lorica of Saint Patrick" or "Saint Patrick's Breastplate." A "lorica" is defined as a mystical garment meant to protect the wearer from evil.
The Lorica poem was later adapted into a hymn text in 1889 by Cecil Alexander titled "I Bind Unto Myself Today," with Charles V. Stanford writing the melody.
