Matthew 28:18-20 (New International Version)
18Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. 19Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
St. Patrick is an excellent example of someone that was moved by the command of Jesus, as noted in the above verses, to make a difference with people in his time.
St. Patrick's Day is celebrated on March 17, his religious feast day and the anniversary of his death in the fifth century. The Irish have observed this day as a religious holiday for over a thousand years. On St. Patrick's Day, which falls during the Christian season of Lent, Irish families would traditionally attend church in the morning and celebrate in the afternoon. Lenten prohibitions against the consumption of meat were waived and people would dance, drink and feast—on the traditional meal of Irish bacon and cabbage.
St. Patrick of Ireland is one of the world's most popular saints. Apostle of Ireland, born at Kilpatrick, near Dumbarton, in Scotland, in the year 387; died at Saul, Downpatrick, Ireland, 17 March, 461. His parents were Calpurnius and Conchessa, who were Romans living in Britian in charge of the colonies.
As a boy of fourteen or so, he was captured during a raiding party and taken to Ireland as a slave to herd and tend sheep. Ireland at this time was a land of Druids and pagans. He learned the language and practices of the people who held him. During his captivity, he turned to God in prayer. He wrote: "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, where he reunited with his family. He had another dream in which the people of Ireland were calling out to him "We beg you, holy youth, to come and walk among us once more."
He began his studies for the priesthood. He was ordained by St. Germanus, the Bishop of Auxerre, whom he had studied under for years. Later, Patrick was ordained a bishop, and was sent to take the Gospel to Ireland. He arrived in Ireland March 25, 433, at Slane. Patrick began preaching the Gospel throughout Ireland, converting many. He and his disciples preached and converted thousands and began building churches all over the country. Kings, their families, and entire kingdoms converted to Christianity when hearing Patrick's message(Patrick used the shamrock to explain the Trinity, and it has been associated with him and the Irish since that time).
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 church.
Patrick was a humble, pious, gentle man, whose love and total devotion to and trust in God should be a shining example to each of us. He feared nothing, not even death, so complete was his trust in God, and of the importance of his mission.
