The question of “who owns the Church” has had a stormy history in Catholic America, although the terms of reference have changed considerably over time.
In the 19th century, “lay trusteeism” — lay boards that owned parish property and sometimes claimed authority over the appointment and dismissal of pastors — was a major headache for the U.S. bishops.
Today, the question is more likely to arise from the wetlands of psychobabble; thus one Midwestern diocesan chancellor recently spoke about a diocesan “needs assessment” that “can give ownership to the people,” presumably of their lives as Catholics.
