=== Validity of the Council ===
{{See also|Traditionalist Catholicism|Sedevacantism|Sedeprivationism}}
Some Traditionalist Catholics claim that several council statements conflict with established teaching regarding faith, morals and doctrine, and are therefore in error.<ref>{{Cite web |title=Twenty-five explicit errors of Vatican Council II |url=http://www.catholicapologetics.info/modernproblems/vatican2/vatican2.htm |access-date= |website=  |language=en}}</ref> As a result, they say, Vatican II is invalid.

The largest of the traditionalist groups rejecting the validity of Vatican II is the [[Society of Saint Pius X]] (SSPX), which recognizes the authority of the Pope but rejects the validity of the Second Vatican Council. In 1988, the SSPX faced a conflict with [[Pope John Paul II]] over the consecration of bishops ([[Écône consecrations]]), which led to disputed canonical sanctions. This event has been a subject of ongoing debate within the Catholic community regarding the validity of any purported excommunications.<ref>{{Cite web |title=Marcel Lefebvre |url=https://www.britannica.com/biography/Marcel-Francois-Lefebvre |access-date= |website=[[Encyclopædia Britannica]] |date=25 November 2023 |language=en}}</ref><ref>{{Cite web |last=Esteves |first=Junno Arocho |date=4 April 2017 |title=Pope approves provisions to recognize marriages of SSPX faithful |url=https://www.ncronline.org/pope-approves-provisions-recognize-marriages-sspx-faithful |access-date= |website=[[National Catholic Register]] |language=en}}</ref><ref>{{Cite web |last=Casey |first=Paul M.D |date=28 April 2023 |title=SSPX Masses and Fulfilling the Sunday Obligation |url=https://catholicfamilynews.com/blog/2023/04/28/sspx-masses-and-fulfilling-the-sunday-obligation/ |access-date= |website=[[Catholic Family News]] |language=en}}</ref>

Other groups have gone further than the SSPX and have declared that the Holy See has been vacant since the death of [[Pope Pius XII]] ([[sedevacantism]]) or that all the Pontiffs since Pope John XXIII are popes [[Hylomorphism|materially but not formally]] ([[sedeprivationism]]). The most notable of these groups are the [[Congregation of Mary Immaculate Queen]] and the [[Istituto Mater Boni Consilii|Institute Mater Boni Consilii]].<ref>{{Cite book |last=Chryssides |first=George D. |url=https://books.google.com/books?id=LgvvaMgTsZ0C&q=sedevacantists&pg=PT75 |title=Historical Dictionary of New Religious Movements |publisher=[[Scarecrow Press]] |year=2011 |isbn=978-0-8108-7967-6 |pages=310 |language=en}}</ref><ref>{{Cite book |last=Pasulka |first=Diana Walsh |url=https://books.google.com/books?id=0fqKBAAAQBAJ |title=Heaven Can Wait: Purgatory in Catholic Devotional and Popular Culture |publisher=[[Oxford University Press]] |year=2015 |isbn=978-0-19-538202-0 |pages=180 |language=en}}</ref>
