"The love of God and his fear grew in me more and more, as did the faith, and my soul was rosed, so that, in a single day, I have said as many as a hundred prayers and in the night, nearly the same. I prayed in the woods and on the mountain, even before dawn. I felt no hurt from the snow or ice or rain."
Patrick's captivity lasted until he was twenty, when he escaped after having a dream from God in which he was told to leave Ireland by going to the coast. There he found some sailors who took him back to Britain and was reunited with his family.
The vision prompted his studies for the priesthood. He was ordained by St. Germanus, the Bishop of Auxerre, whom he had studied under for years, and was later ordained a bishop and sent to take the Gospel to Ireland.
Patrick arrived in Slane, Ireland on March 25, 433. There are several legends about what happened next, with the most prominent claiming he met the chieftan of one of the druid tribes, who tried to kill him. After an intervention from God, Patrick was able to convert the chieftain and preach the Gospel throughout Ireland. There, he converted many people -eventually thousands - and he began building churches across the country.
He often used shamrocks to explain the Holy Trinity and entire kingdoms were eventually converted to Christianity after hearing Patrick's message.
Patrick preached and converted all of Ireland for 40 years. He worked many miracles and wrote of his love for God in Confessions. After years of living in poverty, traveling and enduring much suffering he died March 17, 461.
He died at Saul, where he had built the first Irish church. He is believed to be buried in Down Cathedral, Downpatrick. His grave was marked in 1990 with a granite stone.
