Idassa, Algeria

When Pope Francis appointed Father Joseph Williams as bishop-elect of the Archdiocese of St. Paul and Minneapolis, he also named him titular bishop of Idassa.

Where is that? What does that mean?

A quick internet search (GCatholic.org) traces Idassa to an area in present-day Algeria. As a “titular see,” Idassa was once the seat of a Catholic diocese, but is no longer. Titular sees are former dioceses that have been suppressed or substantially reconfigured and the location of the cathedral transferred to another location, often because they fell into the hands of non-Christian conquerors, were part of a schism, or the number of Catholics sharply declined or relocated to another part of the diocese.

Auxiliary bishops, including Bishop Williams of the Archdiocese of St. Paul and Minneapolis, as well as bishops holding titles and responsibilities that do not entail overseeing a specific diocese, such as papal nuncios, vicars apostolic and superiors of departments in the Roman Curia, are given a titular see in recognition of their episcopal status, said Susan Mulheron, a canon lawyer and the archdiocese’s chancellor of Canonical Affairs.

While auxiliary bishops are sacramentally equal to a diocesan bishop, such as Archbishop Bernard Hebda in St. Paul and Minneapolis, they serve under the diocesan bishop’s jurisdiction, Mulheron said. Being appointed to a titular see, while not conferring any actual governing duties, recognizes in a special way the responsibility that belongs to all bishops, who participate in Christ’s threefold ministry of teaching, sanctifying and governing.

The last bishop to hold the titular see of Idassa was Bishop Gianpiero Palmieri, from 2018 when he served as auxiliary bishop and then archbishop vice regent of Rome, until his appointment in October as bishop of the Diocese of Ascoli Piceno in Italy.

When Bishop Andrew Cozzens of Crookston was auxiliary bishop of the archdiocese from 2013 until October, his titular see was Bisica, an area in today’s Tunisia.
