Third Council of Baltimore

The Plenary Councils of Baltimore were three national meetings of Catholic bishops in the United States in 1852, 1866 and 1884 in Baltimore, Maryland.

During the early history of the Roman Catholic Church in the United States all of the dioceses were part of one ecclesiastical province under the Archbishop of Baltimore. This being the case, governance of the American church was carried out by provincial councils held in Baltimore. As the church grew and was divided into multiple provinces, it became necessary for a national (or plenary) council of the bishops of the United States to meet to foster common discipline.

The fathers of the Seventh Provincial Council of Baltimore requested the Holy See to sanction the holding of a plenary council. The petition was granted and the pope appointed Archbishop Francis Kenrick of Baltimore as Apostolic Delegate to convene and preside over the council.

The First Plenary Council of Baltimore was solemnly opened on May 9, 1852. Its sessions were attended by six archbishops and thirty-five suffragan bishops. The Bishop of Monterey, California, Joseph Sadoc Alemany, was also present, although his diocese, lately separated from Mexico, had not yet been incorporated with any American province. Another prelate in attendance was Armand de Charbonnel, the Bishop of Toronto, Canada. The religious orders and congregations were represented by the Mitred Abbot of St. Mary of La Trappe and by the superiors of the Augustinians, Dominicans, Benedictines, Franciscans, Jesuits, Redemptorists, Vincentians, and Sulpicians. The last solemn session was held on the 20th of May.
