McEntegart was ordained to the priesthood for the Archdiocese of New York by Cardinal John Farley on September 8, 1917. In 1918, he earned a Master's degree from Catholic University of America with a thesis entitled: "The Care of the Poor in New York in the 17th Century."[3] McEntegart then served as a curate at Sacred Heart Parish in New York City until 1923, when he was transferred to St. Patrick's Cathedral.[4]
From 1953 to 1957, McEntegart served as rector of the Catholic University of America.[2] He was assigned the titular see of Aradi on August 19, 1953. During his administration, he embarked on a large fund-raising campaign to expand all phases of the university's work.[3]
Bishop of Brooklyn
Pope Pius XII appointed McEntegart as the fourth bishop of the Diocese of Brooklyn on April 16, 1957, the largest diocese in the United States in terms of Catholic population.[3] He was installed by Cardinal Francis Spellman on June 13, 1957. During his tenure he launched a multimillion-dollar building program, which included six high schools, Cathedral Preparatory Seminary in Queens, New York, a hospital, a college for training Long Island's priests, and a four-year theological seminary.[3] He promoted outreach to the growing Hispanic population, sending priests and religious to study Spanish language and culture.[7] He attended all four sessions of the Second Vatican Council between 1962 and 1965; he implemented the reforms of the council, becoming a pioneer in the ecumenical movement and establishing the Pastoral Institute in 1967.[7] He was given the personal title of archbishop by Pope Paul VI on April 15, 1966.
Retirement
In early 1968, McEntegart tendered his resignation as Bishop of the Diocese Brooklyn because of poor health, and Pope Paul VI accepted it on July 17, 1968.[1] Two months later, after suffering a stroke, Bryan McEntegart died at his residence in the Fort Greene section of Brooklyn at age 75.[3]
