Father Luke Callaghan
Father Luke Callaghan was considerably younger than his two older brothers (Fr. Martin and Fr. James) who served as priests. He was born on 2 February 1865 in Montreal. He studied at the College de Montreal from 1877-1884, and then at the Grand Seminaire to 1889 where he studied philosophy and theology. After having been ordained he was chaplain at L'Hotel Dieu Hospital and the Royal Victoria Hospital. In 1895 he left for Rome where he earned a doctorate in theology from Urban University. In 1898 he was assistant Chancellor at the Archbishop's Palace which is situated on De La Gauchetiere and he resided at 873 De La Gauchetiere. In 1903 he served at St. Patrick's, under his brother Father Martin Callaghan. Father Luke remained at St. Patrick's until at least 1907, when he returned to Rome to continue his studies. In September 1904, Father Luke had the honour of delivering the first sermon ever given in English at Notre Dame Basilica.
In 1907 he returned to his position as Vice Chancellor at the Archbishop's Palace, residing at 471 De La Gauchetiere West.
From 1910-1931 Father Luke was the parish priest at St. Michael's Church and lived at 1634 St. Denis. Money for the building of St. Michael's Church was raised by Father Luke and came largely from Irish parishoners who moved from Griffintown to this area of Montreal, the area of St. Viateur Street, St. Denis Street, and Clarke Street. Father Luke proved to be both an excellent administrator and beloved priest. A landmark in Montreal, the impressive St. Michael's is constructed in the Byzantine style of architecture, modelled on the Basilica of Saint Sophia in Constantinople. Father Luke Callaghan died 12 April 1931 at the age of sixty-three years.
