What were the major events in st patricks life?

Answer 1

There were many miracles ascribed to St. Patrick. Three of those miracles are bringing a horse back to life, converting people who hated him, and telling a group of starving sailors to believe in God after which a herd of pigs appeared.

Answer 2

I don't think I can manage to come up with 3, however, I'd have to say that St.Patrick's biggest accomplishment was escaping Ireland and returning to his home, then to return to Ireland and preach Christ to the people

Answer 3

If you mean the canonization miracles of Saint Patrick, he was declared a saint long before the canonization process was instituted and miracles were not required at the time.
