It is the day that a Saint named Patrick scared the snakes and lizards from Ireland. When the creatures left, you could see the greens of the grasses and the animals that still lived. He pretty much "saved" spring from evil. lizards and snakes ate the calvs and lambs not long after they were born. This made it hard to celebrate easter because easter is a celebration of rebirth and new beginnings.
St. Patrick: Guided By Visions After more than six years as a prisoner, Patrick escaped. According to his writing, a voice?which he believed to be God's?spoke to him in a dream, telling him it was time to leave Ireland.
To do so, Patrick walked nearly 200 miles from County Mayo, where it is believed he was held, to the Irish coast. After escaping to Britain, Patrick reported that he experienced a second revelation?an angel in a dream tells him to return to Ireland as a missionary. Soon after, Patrick began religious training, a course of study that lasted more than 15 years. After his ordination as a priest, he was sent to Ireland with a dual mission: to minister to Christians already living in Ireland and to begin to convert the Irish. (Interestingly, this mission contradicts the widely held notion that Patrick introduced Christianity to Ireland.)
What initially started as a Catholic holiday became an official feast day in the 17th century. Since then it has become a secular celebration of the Irish culture. Neither Saint Patrick or St. Patrick's Day is mentioned in Scripture. While we would strongly disagree of some of the aspects of Catholic theology that St. Patrick taught, the fact that around 1600 years ago a man dedicated his life to proclaiming the Gospel, resulting in tens of thousands coming to faith in Christ - that is most definitely worth celebrating (Luke 15:7-10).
