St. Patrick is known for his religious teachings and missionary work in Ireland, and as such, he is often associated with several spiritual quotes and prayers. However, he is not known to have had a specific motto. One of his most famous teachings, known as the "Breastplate of St. Patrick" or "St. Patrick's Prayer," is a spiritual reflection that expresses his faith and devotion to God. The prayer includes the following verse:
"Christ with me, Christ before me, Christ behind me,
Christ in me, Christ beneath me, Christ above me,
Christ on my right, Christ on my left,
Christ when I lie down, Christ when I sit down,
Christ when I arise, Christ in the heart of every man who thinks of me,
Christ in the mouth of everyone who speaks of me,
Christ in every eye that sees me,
Christ in every ear that hears me."
This prayer is often recited on St. Patrick's Day and is considered a representation of St. Patrick's spiritual teachings and beliefs.
