Plagens previously served as bishop of the Diocese of Marquette in Michigan from 1935 to 1940 and as an auxiliary bishop of the Archdiocese of Detroit in Michigan from 1924 to 1935.
Plagens was ordained to the priesthood for the Archdiocese of Detroit by Bishop John Foley on July 4, 1903.[4] After his ordination, Plagens filled the following pastoral assignments in parishes in Michigan:
Pope Pius XI appointed Plagens as the sixth bishop of the Diocese of Marquette on November 16, 1935.[3][5]
In 1938, a transfer of a priest broke into violence. Plagens had ordered the transfer of Father Simon Borkowski, pastor of St. Barbara's Parish in Vulcan, Michigan, to a seminary in Wisconsin. However, Borkowski had refused to go, instead remaining inside his church with 20 supporters picketing outside. One day, a group of sixty men arrived at St. Barbara's, pushed past the picketers, and brought Borkowski out of the building. The newly appointed pastor, Father Erasmus Dooley, was allowed to enter. However, a group of 100 Borkowski supporters soon arrived and a full-scale brawl erupted. In the end, Dooley left the church and Borkowski re-entered it.[6]
Bishop of Grand Rapids
Pope Pius XII named Plagens as bishop of the Diocese of Grand Rapids on December 16, 1940.[4] He was installed on February 18, 1941.[4][3]
Joseph Plagens died at St. Mary's Hospital in Grand Rapids on March 31, 1943, at age 63 of coronary thrombosis.[7] He was originally buried at Mount Calvary Cemetery in Grand Rapids, but was later removed to Resurrection Cemetery in Wyoming, Michigan.
