1700 to 1930 During the 17th century, present-day Michigan was part of the French colony of
New France. The Diocese of Quebec had jurisdiction over the region. In 1763, the Michigan area became part of the British
Province of Quebec, forbidden from settlement by American colonists. After the
American Revolution, the Michigan region became part of the new United States. For Catholics, Michigan was now under the jurisdiction of the
Archdiocese of Baltimore, which then comprised the entire country. In 1808,
Pope Pius VII erected the
Diocese of Bardstown in Kentucky, with jurisdiction over the new
Michigan Territory. In 1821, the pope erected the Diocese of Cincinnati, taking the Michigan Territory from the Diocese of Bardstown. The first Catholic church in the Saginaw Valley was St. Joseph, dedicated in 1850 in
Bay City. St. Mary's Parish in Saginaw, the first in that community, was established in 1853 as a mission of St. Joseph.
1930 to 1950 Pope Pius XI formed the Diocese of Saginaw in 1938 out of 16 Michigan counties that he separated from the
Diocese of Grand Rapids and the
Archdiocese of Detroit. The pope appointed
William F. Murphy from Detroit as the first bishop of Saginaw. The 1938
P.J. Kenedy Official Catholic Directory notes that the new diocese had a Catholic population of 77,705, with 81 parishes, 31 missions, 112 priests, 41 parishes with schools (of which 17 were high schools), two hospitals, a children's home and a residence for working girls.
1950 to 1970 After Murphy died in 1950, Auxiliary Bishop
Stephen S. Woznicki from Detroit was made bishop of Saginaw that same year. After
World War II, the diocese underwent tremendous growth, with the diocese establishing new parishes and missions. St. Paul's Seminary was founded in 1957 and
James A. Hickey appointed as rector. The seminary opened in 1961 and closed in 1970. The building is now the diocesan headquarters and home to
Nouvel Catholic Central High School. Woznicki died in 1968, and was succeeded by Bishop
Francis Reh, previously rector of the
Pontifical North American College in Rome.
1970 to 1980 Reh began to implement changes mandated by the
Second Vatican Council in the diocese. A new tenure policy limited priests' assignments to nine years. The former four-deanery division of the diocese was multiplied into 12 vicariates. In 1975, the Cathedral Church of St. Mary was renovated. A liturgy office, a finance board, Latin American affairs department, Black Catholic concerns department, and a human services council were developed. In 1971, the new
Diocese of Gaylord was erected, taking the northern part of the Diocese of Saginaw. Although
Clare County and
Isabella County were added to the Diocese of Saginaw territory, the re-alignment reduced the diocese from 16 to 11 counties.
1980 to 2020 After Reh retired in 1980,
Kenneth E. Untener, rector of
St. John's Provincial Seminary in
Plymouth, became the fourth bishop of
Saginaw. In 1982, Untener initiated a Come Home program at
Christmas time to invite alienated Catholics back to the church. He has also worked to re-establish the traditional practices of Lent. In the 1990s, established a commission for women, a diocesan Office for Stewardship and Development, a Catholic Schools Foundation, and a new Center for Ministry which is located next to the diocesan offices. Untener died of
leukemia in 2004. In 2004, John Paul II appointed Bishop
Robert J. Carlson of the
Diocese of Sioux Falls as the fifth bishop of Saginaw. Carlson emphasized vocations, liturgical renewal, and evangelization within the diocese. The number of seminarians increased from four in 2004 to 12 in 2005, and to 19 in 2006. The first
permanent deacon in over 25 years was ordained in 2006, and two men were ordained to the transitional diaconate in that same year. The diocese has also implemented a series of
Saint Andrew dinners to invite young men to an informal meal and discussion on vocations. In 2007 the diocese began an evangelization initiative to reach out to all families in the diocese through the Faith Saginaw magazine. A group of 230 people took part in the
March for Life in
Washington, D.C., In 2009, Auxiliary Bishop
Joseph Cistone, of the
Archdiocese of Philadelphia, was transferred to Saginaw to be its new bishop. In March 2018, Saginaw police executed a
search warrant at Cistone's residence along with the chancery and cathedral rectory. They had been dissatisfied with the cooperation they had been receiving from Cistone in the investigation of sexual abuse allegations against Robert DeLand. Cistone served until his death from
lung cancer in 2018. Bishop
Robert Gruss of the
Diocese of Rapid City succeeded him.
2020 to present Early in 2020, as a result of the
COVID-19 outbreak, Bishop Gruss suspended mass throughout the diocese. By the summer of 2021, the diocese permitted parishioners who had received
COVID-19 vaccination to attend mass without masks.
Sex abuse Megan Winans, a
Central Michigan University student, sued the Diocese of Saginaw in February 2016. She claimed that Reverend Denis Heames had misused counseling sessions to draw her into a sexual relationship. Heames was parochial administrator at St. Mary University Parish in
Mount Pleasant until the diocese removed him in July 2015 for "boundary violations". Soon after Winans filed her lawsuit, the diocese verified that Heames had sexually harassed her. Robert DeLand was indicted on
criminal sexual conduct in March 2018 by a 17-year-old male and a 21-year-old male. The two accusers said that the priest showed them
pornography and inappropriately touched them. After the
indictment, more alleged victims came forward. Also in March 2018, DeLand's teenage victim sued the diocese. DeLand was acquitted of charges in his first trial but pleaded
no contest in a second separate trial in March 2019 on criminal sexual conduct. He was sentenced to two to 15 years in prison. DeLand was laicized by the Vatican in November 2022. In November 2018, the diocese released a list of 18 deceased priests with credible accusations of sexual abuse of a minor. ==Bishops==
