Bishop David M. O’Connell, C.M
A priest of the Eastern Province of the Congregation of the Mission, also known as the Vincentians, Bishop O’Connell grew up in Langhorne, Pa. He is one of four sons of the late June O’Connell, who passed away July 22, 2015, and the late Arthur J. O’Connell, who passed away Aug. 21, 2005. His brothers, Arthur Jr., Dennis and Daniel, all reside in the Philadelphia area.
The family were longtime members of Our Lady of Grace Parish, Penndel, Pa. He attended the parish grammar school, where he was taught by the Immaculate Heart of Mary Sisters. Knowing from an early age that he wished to pursue the priesthood, Bishop O’Connell attended the Vincentians’ St. Joseph Preparatory High School,
Princeton. He continued his Vincentian education in Niagara University, New York, where he obtained a bachelor’s degree in philosophy in 1978.
Bishop O’Connell prepared for the priesthood in Mary Immaculate Seminary, Northampton, Pa., where he received a master of divinity degree in 1981 and a master’s degree in moral theology in 1983.
On May 29, 1982, he was ordained a priest of the Congregation of the Mission in Mary Immaculate Seminary by Bishop Joseph McShea of the Diocese of Allentown.
On June 4, 2010, Pope Benedict XVI appointed then-Father O’Connell as Coadjutor Bishop of the Diocese of Trenton. He was ordained to the episcopacy by Bishop John M. Smith in St. Mary of the Assumption Cathedral, Trenton, on July 30, 2010. When Pope Benedict XVI accepted the resignation of Bishop Smith on Dec. 1, 2010, Bishop O’Connell automatically succeeded him as the 10th Bishop of Trenton.
