On September 7, 1903, Broderick was appointed by Pope Pius X as the
Auxiliary Bishop of the Archdiocese of San Cristóbal de la Habana and
Titular Bishop of
Iuliopolis.
Restoration to episcopal life On the eve of
Francis Spellman's May 23, 1939, installation as Archbishop of New York, Cardinal
Amleto Cicognani, the
apostolic delegate to the United States, asked Spellman to look into the matter of Broderick's long exile. In 1942, at the dedication of a new wing to the Schervier facility, Spellman said: "The greatest thing I have done for my soul and the greatest gift I have brought to the people of the archdiocese has been in bringing Bishop Broderick to New York." Also in 1942, Spellman named Broderick the vicar for
religious in the archdiocese. James K. Hanna has written a biography of Broderick, titled "The Remarkable Life of Bishop Bonaventure Broderick: Exile, Redemption, and a Gas Station" (Serif Press, 2022). The Remarkable Life of Bishop Bonaventure Broderick ==Final years and death==
