This province is composed of the Archdiocese of Detroit (the metropolitan) along with the dioceses of Gaylord, Grand Rapids, Kalamazoo, Lansing, Marquette, and Saginaw as suffragans, all in the state of Michigan.
Archbishop Allen Henry Vigneron (61) is the ordinary for the Archdiocese of Detroit. Since the former ordinary, Adam Joseph Cardinal Maida, turns 80 in March of the coming year, Archbishop Vigneron is likely to be named a Cardinal if the consistory is held after that date.
The Archdiocese is down to a single active Auxiliary Bishop: Bishop Francis Ronald Reiss (69). It is likely that several more will be added in the coming year or two.
The Diocese of Gaylord is led by Bishop Bernard Anthony Hebda (50). His consecration as bishop was held on the 1st of this month.
Bishop Walter Allison Hurley (72) is the ordinary of the Diocese of Grand Rapids. He will celebrate 45 years as a priest next June.
Bishop Paul Joseph Bradley (64) is the leader of the Diocese of Kalamazoo. He is also a recent addition to this province, having previously served as an Auxiliary Bishop in Pittsburgh.
The Diocese of Lansing is led by Bishop Earl Alfred Boyea, Jr. (58). While none of his predecessors were transferred, he might be the first, but probably not in the next several years.
Bishop Alexander King Sample (49) is the ordinary of the Diocese of Marquette. He will celebrate 20 years as a priest next June.
Finally, the Diocese of Saginaw is led by Bishop Joseph Robert Cistone (60). His 35th anniversary of being ordained a priest falls in May. He will likely remain the ordinary here for many years. (Granted I said the same thing about his predecessor who is now the Archbishop of St. Louis, Missoui!)
After all of the changes this province has seen in the last few years, it is likely to be much more stable in the next few. The only changes I expect are a red hat and several new auxiliary bishops for Detroit.
