According to tradition, one of the high druids challenged Patrick to a supernatural duel to determine whose god was greater. The druid invoked demons and even levitated before the crowd, but Patrick, filled with the power of Christ, commanded them to fall. The wizard crashed to the ground and died. Witnessing this, the king was shaken. Convinced of God’s power, he allowed Patrick to continue preaching. Over the next 30 years, Patrick baptized thousands, converted chieftains, and used the shamrock to explain the mystery of the Trinity. Through him, Ireland was set on the path to becoming one of the most Christian lands in Europe.
