Are you sitting down?
Saint Patrick was not Irish.
Yep he was a Roman citizen living in Scotland where he was kidnapped by the Irish and made a slave. A pig herder to be exact. He escaped and fled to France where he accepted Christ and went to seminary and became a monk. He was reunited with his family and had a good life when a dream told him to go back to Ireland and convert those who had enslaved him. He had a message for the common man because he had traveled all walks of life. It was his way of explaining the trinity by using a shamrock — Father, Son, and Holy Spirit. Three in one. And that became the symbol of Ireland.
Now you know the rest of the story!
