St. Laserian was said to have been of noble birth. St. Laserian was the son of Cairel de Blitha, a ”Ulidian” noble celt, and Gemma, daughter of a Scottish king. He was born around the year 566. He is commonly known as Molaise. The names Laisren or Molaise are to be found in ancient manuscripts and occur for instance in The Book of Leinster and in The Calendar of Oengus. The name Laisren comes from the Gaelic name for flame, usually “lasair”. The ”Molaise” form of the name derives from placing the personal Gaelic pronoun “Mo” ahead of the name Laisren and thus meaning “My Light” the light being from a pyre (flame).
Laserian was sent to Scotland to get his education from monks, beginning from a young age. He was educated by a monk called Munus. On his return home, he refused his right to the kingship of his clan, preferring a life of solitude as a hermit. He lived his youthful life as a hermit in the cell of a cave on Holy Island off the coast of the Isle of Arran in the west of Scotland. This island became known as Molaise’s island. He worked many miracles there; enabling water to flow when it was needed for milling for example. At a later stage in his life he restored a beheaded boy back to life. After his time in soliitude, he set out for Rome, where he studied for fourteen years and was ordained a priest by Gregory the Great. Reverend Laserian then journeyed back to Ireland to preach the faith.
As a priest he established a monastic community at Old Leighlin in present day Carlow in the late sixth century. His choice of location was said to have been inspired by Divine Guidance. He went first to Lorum Hill, south east of Muinebheag, in Carlow. From here he was directed by an angel to go to where he would see the sun first shining and set up his religious foundation there. The place thus chosen was Old Leighlin Hill.
Now Laserian crossed the River Barrow and came to Old Leighlin. But a holy abbot named Gobanus and his followers were already settled there. Gobanus and his community moved on and allowed Rev. Laserian to establish his monastery at Old Leighlin. The monastic community grew, and the establishment became famous, containing as many as 1500 monks.
St. Laserian was a very faithful priest and took the leading part in settling the Irish Easter calender controversy. In the Synod of Magh-lene he successfully defended the Roman Easter calendar computation, and was sent by the council as delegate to Rome. There, in 633, he was consecrated first Bishop of Leighlin by Honorius I. On his return from the eternal city, bishop Laserian pleaded the cause of the Roman Easter calendar so powerfully at another synod in Leighlin that the controversy was practically ended for the greater part of the country. Of course the Celtic Easter calendar would rear it’s head again over the following centuries. But St. Laserian was among the first pioneers to change this and bring the Roman Easter Calendar into regular usage in Ireland.
The original wooden church dedicated to the bishop of Leighlin was plundered several times both by the Danes and by the native Gaels. In later times, a cathedral stood in its place, but in the reign of Henry VIII it was seized by the Reformers, was made a Protestant church, and has continued as such ever since.
The Catholic Church in Ireland celebrates St. Laserian on the 18th April
