# Roman Catholic Diocese of Great Falls–Billings

The Diocese of Great Falls–Billings (Latin: Dioecesis Magnocataractensis–Billingensis) is a Latin Church diocese of the Catholic Church in eastern Montana in the United States.
The Diocese of Great Falls was established in 1904; it became the Diocese of Great Falls-Billings in 1980. The bishop of Great Falls-Billings is Jeffrey Fleming. The diocese has two cathedrals: St Ann's Cathedral in Great Falls, dedicated in 1907, and St Patrick's Co-Cathedral in Billings, dedicated in 1908.

## History
### 1800 to 1883

The earliest Catholic presence in present-day Montana was the arrival of Catholic Iroquois/Haudenosaunee fur traders who settled with the Flathead Nation in western Montana around 1811. After hearing about Catholic missionaries from the Iroquois visitors, the Flathead nation sent emissaries to St. Louis, Missouri, four times in the 1830s to petition the Diocese of St. Louis for their own missionaries. At that time, the diocese was responsible for large territories east of the Rocky Mountains.
Finally, in 1840, the Diocese of St. Louis sent missionary Reverend Pierre-Jean de Smet to Montana. Encouraged by his reception by the Flathead Nation, de Smet returned the following year to establish missions. The missions founded by Jesuit missionaries in eastern Montana included:
* St. Xavier's Mission in St. Xavier for the Crow Nation (1840)
* St. Peter's Mission near Cascade for Métis settlers from Canada (1874)

### 1883 to 1900

In 1883, Pope Leo XIII erected the Apostolic Vicariate of Montana, including eastern Montana, with territory taken from the Diocese of St. Louis. He appointed Bishop Jean-Baptiste Brondel of the Diocese of Vancouver Island as the apostolic vicar.
One year later, the same pope created the Diocese of Helena to replace the vicariate. Eastern Montana would be part of the Diocese of Helena for the next 21 years. In 1884, Brondel purchased land in present-day Ashland to found the St. Labre Indian School, staffed by Ursuline Order sisters.
The first Catholic parish in Billings, St. Patrick's, was established in 1887.

### 1900 to 1930

Pope Pius X erected the Diocese of Great Falls on May 18, 1904, taking eastern Montana from the Diocese of Helena. The pope named Reverend Mathias Lenihan from the Diocese of Dubuque as the first bishop of the new diocese.
Lenihan served as bishop for 26 years. He was involved in temperance reform, building the parochial school system, and constructing a new cathedral. The new St. Ann Cathedral in Great Falls was dedicated in 1907. Lenihan was instrumental in establishing an orphanage staffed by the Sisters of Charity of Providence.
In 1913, Lenihan introduced Benedictine sisters from Germany to minister to minister in Poplar to Native Americans at the Fort Peck Indian Reservation. The diocese also established several new parishes during his episcopate. Lenihan retired in 1930.

### 1930 to 1980

The second bishop of Great Falls was Reverend Edwin O'Hara from the Diocese of Oregon City, named by Pope Pius IX in 1930. Concerned at the lack of doctrinal education among rural Catholic children, O'Hara introduced the Confraternity of Christian Doctrine (CCD) program in the diocese in 1930. O'Hara worked to implement CCD throughout his diocese and the United States. His efforts led to a revitalization of CCD and rapid adoption of it throughout the country. O'Hara then promoted the establishment of CCD neighborhood groups of four to six adults to study a single work for eight weeks, twice a year. By 1934, more than 400 adult CCD groups existed in the diocese. The movement spread nationwide, with tens of thousands of adult groups. O'Hara became bishop of the Diocese of Kansas City in 1939.
To replace O'Hara, Pope Pius XII appointed Monsignor William Condon from the Diocese of Spokane. Condon retired in 1967. His replacement was Auxiliary Bishop Eldon Schuster of Great Falls, named bishop by Pope Paul VI that same year. Shuster retired in 1977.
In 1978, Reverend Thomas Murphy of the Archdiocese of Chicago was appointed bishop of Great Falls-Billings by Paul VI.

### 1980 to 2010

On February 14, 1980, Pope John Paul II renamed the Diocese of Great Falls to the Diocese of Great Falls-Billings to reflect the population growth in Billings. In 1987, Murphy became the coadjutor archbishop of the Archdiocese of Seattle.
To replace Murphy in Great Falls-Billings, John Paul II appointed Auxiliary Bishop Anthony Milone from the Archdiocese of Omaha. In 2005, the Northern Cheyenne Nation sued the St. Labre Indian School in Ashland and the Diocese of Great Falls-Billings. The plaintiff alleged that both organizations used the tribe's poverty to raise millions of dollars, but shared almost none of it with the nation. The lawsuit claimed breach of contract, cultural genocide, fraud, and unjust enrichment.
Murphy retired early in 2006 due to health concerns. Pope Benedict XVI then named Bishop Michael Warfel from the Diocese of Juneau as the next bishop of Great Falls-Billings.

### 2010 to present

In 2013, the Montana Supreme Court reversed parts of a lower court ruling dismissing the Northern Cheyenne suit. However, the Supreme Court did say that the Northern Cheyenne had failed to prove allegations of breach of contract, negligent misrepresentation, fraud and wrongful conversion. The court also out claims of cultural genocide. The Northern Cheyenne and St. Labre School reached an out-of-court settlement in December 2014. The school agreed to pay the nation $6 million in 2014, $1 million per year from 2015 to 2019, and $60,000 per year beginning in 2020.
In early 2016, the diocese created the Diocese of Great Falls-Billings Juridic Persons Capital Assets Support Corporation (the "Capital Assets Support Corporation", or CASC), a non-profit organization. The diocese then transferred most of its cash and assets to CASC by the end of 2016. Critics accused the diocese of trying to protect the church's assets from victim claims by transferring them to an organization it controlled. In March 2017, the diocese filed for Chapter 11 bankruptcy in the light of multiple lawsuits for sexual abuse of minors by clergy.
In July 2018, Warfel reprimanded two priests from the diocese. The priests, wearing clerical garb, had attended a political rally in Great Falls for President Donald Trump. The rally organizers had seated the two priests in highly visible positions in the first row behind the podium. The priests were seen clapping when Trump joked about the MeToo movement and when he referred derisively to U.S. Senator Elizabeth Warren as "Pocahontas". Warfel later told the priests that they should have worn civilian clothes to the rally and should have requested less visible seats.
Warfel retired in 2023. Jeffrey M. Fleming, who had served as coadjutor bishop of the diocese since April 19, 2022, automatically became its bishop on August 22, 2023.

### Sexual abuse

In 2012, the first of several sexual abuse lawsuits was filed against the diocese, alleging abuse of both boys and girls by diocesan clergy and employees. Over 60 plaintiffs had joined the suits by April 2015. By 2017, the diocese faced more than 400 potential sexual abuse lawsuits.
In March 2017, just weeks before the first sexual abuse trials were to begin, the diocese filed for Chapter 11 bankruptcy. The diocese then agreed to compensate 72 plaintiffs in the lawsuits and establish a fund to compensate future unknown victims. In response, the alleged victims and other church creditors sued the diocese in January 2018. They alleged that the diocese illegally triggered its bankruptcy by creating CASC, in what they termed as a fraudulent attempt to hide $16 million assets. The victims also argued that the assets of 14 of the 50 parishes should be considered diocesan assets and subject to entailment. In response to this lawsuit, the diocese filed a motion to dismiss its bankruptcy proceeding. Another 14 victims came forward after the bankruptcy filing.
In April 2018, the diocese and the sexual abuse victims announced a new bankruptcy plan and settlement, with terms similar to the 2015 bankruptcy filing by the Diocese of Helena. In addition, the Great Falls-Billings plan also required the diocese to begin "intensive background checks and screening of potential seminarians" and to publish a list of all known abusers, past and present, that were named in the lawsuits.
A federal court approved the new Great Falls-Billings bankruptcy plan in August 2018. The diocese would pay $20 million to 86 alleged victims, setting aside another $1.75 million to cover administrative costs and to compensate f victims who came forward in the future. The 86 victims were to receive their payments within a month. The $20 million was to come from the following sources:
* Catholic Mutual, the diocese's liability insurer ($8 million)
* The diocese ($4 million)
* Individual parishes ($4 million)
* CASC ($2 million)
* The Catholic Foundation of Eastern Montana ($1 million)
* St. Labre Indian School ($1 million)
In November 2018, Reverend Lothar Krauth, a retired priest from Our Lady of Lourdes Parish in Great Falls, was arrested on charges of possessing child pornography. Receiving a tip from the US Department of Homeland Security, local police found thousands of images of young children engaged in sexual activity in Krauth's residence. He pleaded guilty to receiving child pornography in April 2019 and was sentenced in October 2019 to five years in prison.
