Facts, myths about St. Patrick
Saint Patrick was a fifth-century Romano-British Christian missionary and bishop in Ireland. Known as the "Apostle of Ireland", he is the primary patron saint of Ireland, the other patron saints being Brigit of Kildare and Columba. Patrick was never formally canonised. Nevertheless, he is venerated in the Catholic Church, the Anglican Communion, the Lutheran Churches, the Old Catholic Church, and in the Eastern Orthodox Church as equal-to-the-apostles and Enlightener of Ireland.
