A Brief History of the Diocese of Pittsburgh

The first Mass in the territory of what would be the Diocese of Pittsburgh was celebrated on April 17, 1754 by Fr. Denys Baron, a
chaplain to the French garrison at Fort Duquesne at the Point. From those humble beginnings, the history of the diocese began.

For the ninety years following the first Mass, the Catholic population in southwestern Pennsylvania region steadily grew, and the Catholic Church grew with it. In 1808, Pittsburgh’s first Catholic parish, Saint Patrick’s in the Strip District, was established. Twenty years later, in 1828, the first Catholic school in the city of Pittsburgh was opened by the Sisters of St. Clare in what is now the city’s North Side.

During this period of early growth, the entire state of Pennsylvania was part of the Diocese of Philadelphia. On August 8, 1843, the diocese was split in half, forming the Diocese of Pittsburgh in the west and Philadelphia in the east. The Irish-born first bishop of Pittsburgh, Bishop Michael J. O’Connor, had served as the vicar general under Bishop Francis Kenrick of Philadelphia and assumed control of the fledgling diocese amidst strong anti-Catholic prejudice and violence.

In part to combat anti-Catholic prejudice, the diocesan newspaper the Pittsburgh Catholic began in 1844. The paper is presently one of the oldest Catholic newspapers in the United States in current circulation and is the second-largest in circulation in Southwestern Pennsylvania.

The last half of the nineteenth century was challenging for the diocese. Catholic immigrants from Central and Eastern Europe seeking work in the steel mills swelled the population. The city was rife with ethnic and labor strife, money was scarce, and anti-
Catholicism was still prevalent. For several decades, the diocese was internally focused, helping immigrants adjust to American society, building schools and parishes, and solidifying its position.

During the early years of the twentieth century, the pace of the church in Pittsburgh’s development began to quicken. In 1908, the United States was finally removed from the list of mission territories. Throughout the United States, the Catholic Church had reached what the Jesuit historian Fr. James Hennesey has called “the end of the beginning.” American Catholics began to emerge out of their cultural and social isolation, seeking to prove that they were just as important, just as strong, and just as American as their Protestant peers.

In Pittsburgh, the growing strength of the Catholic Church was symbolized by Bishop J. F. Regis Canevin, the fifth bishop of Pittsburgh. Born in Beatty, Westmoreland County, Bishop Canevin was the first native son—and the first American-born priest—to become bishop of the diocese.

Throughout his tenure, Bishop Canevin sought to strengthen the diocese’s ability to improve the life of the region as a whole. During the outbreak of the Spanish Influenza following the First World War, the centralized structure that he developed in the Catholic Church in Pittsburgh allowed it to spring into action to help people of every ethnic background and creed.

Bishop Canevin strengthened the financial picture of Catholic institutions as well. Specializing in whirlwind campaigns, he raised millions of today’s dollars to endow Catholic Charities, which had begun under his tenure, and Duquesne University, the Catholic university begun by the Congregation of the Holy Spirit in 1878.

Following the retirement of Bishop Canevin in 1921, Bishop Hugh Boyle, another native son, took charge of the diocese. Born in Johnstown, PA, Bishop Boyle would be bishop until 1950, giving him the longest tenure of all the bishops in Pittsburgh. Through the Roaring Twenties, the Great Depression, the Second World War and the early years of the Cold War, Bishop Boyle guided the diocese with a steady hand.

In August 1931, he also became the first bishop of Pittsburgh to use the emerging mass media, when he took to the airwaves of WCAE (later WTAE) to ask for money to rebuild the Little Sisters of the Poor’s Home for the Aged, which had been tragically destroyed in a fire a few weeks before.

During the 1950s, the city of Pittsburgh was in its prime. The diocese experienced tremendous growth under Cardinal John Dearden, who would go on to become cardinal archbishop of Detroit. Catholics moved to the suburbs, parishes and schools boomed, and the Catholic Church was quickly becoming an accepted part of American society.

Since its formation in 1843, the territory of the Diocese of Pittsburgh had changed several times. In 1853, its northern counties became the Diocese of Erie, and in 1901, the counties in the around Altoona and Johnstown became the Diocese of Altoona-
Johnstown. Early in Cardinal Dearden’s tenure, Westmoreland, Armstrong, Indiana and Fayette Counties split from the diocese to form the Diocese of Greensburg in 1951. Since then, the diocese has had six counties: Allegheny, Beaver, Butler, Greene, Lawrence, and Washington.

The 1960s brought the Second Vatican Council and tremendous change to the Catholic Church. A brilliant intellect who played a part in the Second Vatican Council, Cardinal John Wright sought to steer the diocese through those changes and the tumultuous years of the Vietnam War. The task of implementing the Second Vatican Council in Pittsburgh, however, would fall to Cardinal Wright’s successor, Bishop Vincent Leonard.

Bishop Leonard had to contend with one of the most difficult decades in Pittsburgh’s history. Though it had been declining gradually for decades, the bottom fell out of Pittsburgh’s steel economy during the 1970s. With the recession of the early 1980s, the economic future of the region looked bleak. Population declined drastically, and parishes and schools suffered.

After the short tenure of Cardinal Anthony Bevilacqua, Bishop Donald W. Wuerl assumed leadership of a diocese with an uncertain future. Throughout the 1990s, the diocese underwent a sometimes painful reorganization process as parishes and schools were closed to reflect the region’s demographics. Nationally recognized as “the education bishop,” Bishop Wuerl would emphasize Catholic education and catechesis for all ages and in all media, including a television program based on his best-selling adult
catechism, “The Teaching of Christ.” Bishop Wuerl would become Archbishop of Washington, DC in 2006.

Bishop David A. Zubik was installed as the twelfth bishop of Pittsburgh on September 28, 2007, and announced in his first pastoral letter on June 29, 2008 his goal of a Church Alive! Dividing diocesan administration under four regional vicars, he has overseen a reorganization of diocesan offices geared to serve the needs of the 204 parishes of the diocese while energizing the lay faithful. Despite continuing population decline in the region, under Bishop Zubik’s leadership the diocese remains one of the largest in the country, with 640,000 Catholics or 34 percent of the population in southwestern Pennsylvania.
