Abbot Patrick Mary (Edwin Raphael) O’Brien, was born in
Manchester, NH on October 29, 1885. He attended Saint Anselm’s Prep and later Holy Cross College. His academic life was marked by poor health, a condition which would have an affect on his entire life. Having spent time teaching Latin and History at St. Joseph’s in Manchester, he later went on to enter the novitiate at St. Vincent’s in June 1914. In July 1915 he was professed as a monk of St. Mary’s and returned to St. Anselm’s to study Theology. He was ordained on May 29, 1920. He was appointed pastor of St. Joseph’s in Maplewood in 1933.
In 1937, following the death of Abbot Ernest, Fr. Patrick Mary was elected Abbot. He promptly appointed Fr. Celestine Staab as the pastor of Saint Mary’s Church, a position he would serve in faithfully until 1958. Abbot Patrick, would go on to further develop the Delbarton property at Morristown, which had been purchased by his predecessor. A new monastery (1938) and the Delbarton Prep school (1939) were built on the property.
A major interest of the Abbot was the Sacred Liturgy, and he would serve as a proponent of the Benedictine Liturgical Conference in 1940, encouraging Fr. Benedict Bradley of St. Mary’s to publish what would become known as the Saint Mary’s Missal – which featured not only the text of Liturgy, but also brief histories of the Catholic Church in each of the states of the Union.
With the Second World War, came a need for chaplains for the fighting men of the armed services. Abbot Patrick granted permission to Fathers George Sherry, Maurus Mc. Barron, Eugene Polhemus, Dunstan Smith, Martin Burne, and Philip Hoover to enter the military as chaplains. Also, several foreign monks were granted permission to resided in Newark and Morristown during the war, when they were displaced. By the mid-1950’s the two communities at Newark and Morristown were undergoing tension as each grew and thrived, yet felt held-back by the other. In 1956 Abbot Patrick, presented a plan to transfer the title of Abbey from Newark to Morristown. Following the transfer, the Newark House would revert to the dependent title of St. Mary’s Priory, while the Morristown house would become St. Mary’s Abbey.
During Abbot Patrick’s tenure - St. Benedict’s Prep continued to thrive and in 1958 the prep would see the addition of a new academic building. Culturally the monastery continued to expand as it set up a foundation in Brazil, following the requests of the wider Church. In 1966, the now 81-year-old Abbot Patrick, petitioned Rome for the help of a Coadjutor Abbot. Fr. Martin J. Burne, who had served as Prior in Newark was chosen for this role. On March 30, 1967, Abbot Patrick died, having served for 30 successful and prosperous years.
