History

1700 to 1800

Unlike the other British colonies in America, the Province of Pennsylvania did not ban Catholics from the colony or threaten priests with imprisonment. However, the colony did require any Catholics seeking public office to take an oath to Protestantism.

On November 26, 1784, a year after the end of the American Revolution, Pope Pius VI erected the Apostolic Prefecture of United States of America, including all of the new United States. On November 6, 1789, Pius VI converted the prefecture to the Diocese of Baltimore, covering all of the United States. With the passage of the US Bill of Rights in 1791, Catholics received full freedom of worship.

1800 to 1900

In 1808, the Diocese of Philadelphia, covering the entire new State of Pennsylvania, was erected by Pope Pius VII from the territory of the Diocese of Baltimore.

As the Catholic population grew in Pennsylvania in the 19th century, the Vatican erected the Diocese of Pittsburgh in 1843. The first Catholic church in Altoona, St. John the Evangelist, was dedicated in 1851. St Benedict in Carrolltown was consecrated on Christmas Day in 1850. Pope Pius IX erected the Diocese of Harrisburg in 1868.

In 1899, in the face of rapid growth of the Catholic population of western Pennsylvania, Bishop Richard Phelan of Pittsburgh and Archbishop Patrick John Ryan of Philadelphia asked the Vatican to create a new diocese in the region. Two years later, the Vatican agreed to it.

1900 to 1936

The Diocese of Altoona was erected on May 30, 1901, by Pope Leo XIII, with counties taken from the Dioceses of Pittsburgh and Harrisburg. The pope named Monsignor Eugene A. Garvey from the Diocese of Scranton as the first bishop of the new diocese.

In Garvey's first full year as bishop in 1902, the new diocese contained 59 priests, 44 parishes, 23 parochial schools with 6,000 students, and a Catholic population of 44,000. By his final year as bishop in 1920, there were 148 priests, 91 parishes, 42 parochial schools with 11,369 students, and a Catholic population of 123,756. In early 1920, Pope Pius XI appointed Auxiliary Bishop John Joseph McCort from the Archdiocese of Philadelphia as coadjutor bishop to assist Garvey.

When Garvey died later in 1920, McCort automatically succeeded him as the next bishop of Altoona. McCort laid the cornerstone for the new Cathedral of the Blessed Sacrament in May 1926 but construction temporarily came to a halt in 1929 due to the stock market crash. The cathedral was dedicated in September 1931. In 1922, McCort established Altoona Catholic High School (now Bishop Guilfoyle High School) and Johnstown Catholic High School (renamed Bishop McCort High School in 1962).

1936 to 1986

By the time of McCort's death in 1936, the Diocese of Altoona had 197 priests, 129 churches, 111 parishes, 50 parochial schools, and a Catholic population that had fallen to 100,634 during the Great Depression. Pius XI replaced McCort with Reverend Richard Guilfoyle from the Diocese of Erie in 1936. After 21 years as bishop of Altoona, Guilfoyle died in 1957.

After Guilfoyle died in the summer of 1957, Pope Pius XII renamed the Diocese of Altoona to the Diocese of Altoona-Johnstown to reflect the population growth of Johnstown. In December 1957, the pope appointed Monsignor Howard Joseph Carroll of Pittsburgh as the next bishop of Altoona-Johnstown. Carroll died in 1960.

Pope John XXIII in 1960 appointed Auxiliary Bishop J. Carroll McCormick of Philadelphia as the next bishop of Altoona-Johnstown. In 1966, McCormick became bishop of the Diocese of Scranton. His replacement in Altoona-Johnstown was Auxiliary Bishop James John Hogan of the Diocese of Trenton, selected by Pope Paul VI in 1966.
