The Life

David Dean Kagan was born November 9, 1949, in Waukegan, Illinois, and raised in Spring Grove, Illinois. He studied at Salvatorian Seminary and at Loras College/St. Pius X Seminary in Dubuque, before being sent to the Pontifical North American College in Rome, where he earned a Licentiate in Canon Law from the Gregorian University (1979). He was ordained a priest of the Diocese of Rockford, Illinois, on June 14, 1975.

In Rockford, Kagan spent his career largely in canonical and administrative posts: judicial vicar of the diocesan tribunal, pastor of the Proto-Cathedral of St. James, and for seventeen years vicar general and moderator of the curia. He was elevated to protonotary apostolic (hence the post-nominal 'P.A.'). Pope Benedict XVI named him the seventh Bishop of Bismarck, North Dakota, on October 19, 2011, and he was ordained and installed at the Cathedral of the Holy Spirit on November 30, 2011.

As bishop, Kagan built a reputation as a doctrinally conservative, canonically precise administrator: in 2015 he ended the diocese's affiliation with the Boy Scouts of America over the organization's decision to admit openly homosexual leaders, and in June 2022 he opened the sainthood cause of North Dakota lay missionary Michelle Duppong. He turned 75 on November 9, 2024, and, as required by canon law, submitted his resignation to the pope; as of mid-2026 no successor had been named, and he continued to govern the diocese as its active bishop (past 75, resignation pending -- not emeritus).

Major Works & Initiatives
Provisions for the Latin Mass (decree)
Diocesan decree effective August 1, 2021, regulating the Traditional Latin Mass in the Diocese of Bismarck in response to Traditionis Custodes. It kept the 1962 Missal in use at a designated oratory rather than suppressing it, while imposing the motu proprio's restrictions (non-parish venue, vernacular readings).
Erection of the Oratory of St. Clement
Designated the non-parochial Oratory of St. Clement at Haymarsh, North Dakota, as the stable home of the Traditional Latin Mass, with a priest-delegate charged with the pastoral care of the faithful attached to it.
End of diocesan Boy Scouts affiliation (2015)
Kagan ended the Diocese of Bismarck's sponsorship relationship with the Boy Scouts of America following the BSA's admission of openly homosexual adult leaders.
Cause of Michelle Duppong (2022)
In June 2022 he opened the diocesan investigation into the life of lay Catholic missionary Michelle Duppong for possible beatification and canonization.
In His Own Words
Controversies
TLM confined to a single rural oratory
Kagan's 2021 decree consolidated the diocese's Traditional Latin Mass into the non-parish Oratory of St. Clement at Haymarsh, a rural site west of the Bismarck-Mandan population center, rather than in a city parish. From a traditionalist view this narrowed access even though the Mass itself was preserved.
Vernacular Lectionary and 'before noon' rules
The decree required the readings to be proclaimed from the approved vernacular Lectionary at every TLM and set a before-noon time limit -- implementing the letter of Traditionis Custodes; some traditionalists regard the vernacular-readings mandate as a substantive alteration of the 1962 rite.
Framing as strict obedience to Francis
Kagan explicitly cast the provisions as made 'in accord with and in obedience to' Pope Francis, positioning himself as a compliant executor of Traditionis Custodes rather than a public defender of the older liturgy, even while he chose to preserve rather than abolish it.
Domus Dei’s Verdict
The Bishop & the Mass of Ages
A friend of Tradition

On deeds, Bishop David Kagan sits among the more Tradition-friendly American bishops. When Traditionis Custodes landed in July 2021 and a wave of bishops suppressed or suspended the Traditional Latin Mass outright, Kagan did the opposite: by a decree effective August 1, 2021, he kept the 1962 Missal in continuous use, gave it a stable canonical home at the Oratory of St. Clement in Haymarsh, permitted it every Sunday, and appointed a priest-delegate (Rev. Nick Schneider) with genuine pastoral charge of the attached faithful. In a diocese long known for reverent, orthodox Catholicism, the old Mass survived his administration intact.

The record is not maximalist. Kagan applied the restrictive machinery of the motu proprio to the letter: he moved the Mass out of parish churches into a single non-parochial oratory, mandated the vernacular Lectionary at every celebration, capped the hour before noon, and framed the whole arrangement as obedience to Pope Francis rather than as advocacy for the traditional rite. Access for city faithful in Bismarck-Mandan narrowed even as the Mass itself was safeguarded. This is preservation-through-compliance, not resistance.

For a traditional Catholic audience the balance still tips positive. Kagan preserved what many of his brother bishops extinguished, erected rather than dismantled a home for the old Mass, and paired it with an unambiguously orthodox record on doctrine and discipline. He is regarded as a conservative, canon-law-minded shepherd who chose to keep the door open. Note the status caveat: he passed 75 in November 2024 and has submitted his resignation, but as of mid-2026 no successor had been named and he remained the active Bishop of Bismarck, not emeritus.
