Sedevacantists - Groups

Groups

Sedevacantism appears to be centered in, and by far strongest in, the United States, and secondarily other English-speaking countries. Anthony Cekada has described the United States as a "sedevacantist bastion", contrasting it with France, where the non-sedevacantist SSPX has a virtual monopoly on the traditional Catholic movement.

• Most Holy Family Monastery, a sedevacantist community living in Fillmore, New York, under the headship of Michael (né Frederick) Dimond. Only Michael and his biological brother Peter (né Robert) Dimond write the contents of the website. They are most known for their rigid defense of Extra Ecclesiam nulla salus, and for harshly attacking other traditionalists and sedevacantists who they allege stray from the Church's Magisterium on the matter.
• Society of St. Pius V, formed when nine priests of the Society of St. Pius X split from that organization over a number of issues including using the liturgical reforms implemented under Pope John XXIII. The SSPV maintains that much of the hierarchy of the Roman Catholic Church no longer adheres to the Catholic faith but instead profess a new, or Conciliar religion. They regard the question of the legitimacy of the present hierarchy and the possibility that the Holy See is unoccupied to be unresolved. The SSPV does not impose sedevacantism as a morally binding teaching.
• The Archbishop Thục lines of episcopal succession
• Catholic Restoration, consisting of the founding members — dissenters from SSPV, such as Cekada, Dolan and Sanborn, together with newer priests who were trained in their seminary.
• Congregation of Mary Immaculate Queen
• Apostles of Infinite Love, founded by Michel Collin (actually conclavist).
• Ukrainian Orthodox Greek Catholic Church, who profess the Catholic faith, including the primacy of the Roman Pontiff, but have declared both Pope John Paul II and Pope Benedict XVI excommunicated, leaving the Holy See vacant.
