Saint Patrick (5th century) is the best-known patron saint of Ireland and one of the most successful Christian missionaries in history. He is credited with expanding literacy in Ireland through the monastic orders he established, revising and codifying the Brehon Laws, and converting the country to Christianity. The 17 March celebration started in 1631 when the Church established a Feast Day honouring St Patrick.

An Old Irish Blessing for St Patrick’s Day

May your days be many and your troubles be few.
May all God’s blessings descend upon you.
May peace be within you, may your heart be strong.
May you find what you’re seeking wherever you roam.
May the strength of God pilot us, may the wisdom of God instruct us.
May the hand of God protect us, may the word of God direct us.
May thy Salvation, O Lord, be always ours this day and for evermore.
Amen.
