Ok, I’ll give you a little history:
In 1869 Pope Pius IX convened the First Vatican Council (for clarification purposes, a General Council is named after the place it is held in- though some Councils in history bear the same name they are not necessarily related in their topics of discussion). This Council was called to discuss the issues Pius IX had already written about in his famous document the Syllabus of Errors, and to address the matter of Papal Infallibility (the dogma that, under certain circumstances, the Pope speaks infallibly in matters of faith and morals). Papal Infallibility was officially defined in the Council’s document Pastor Aeternus, but before other issues could be addressed the Masonic Revolutionaries in Italy invaded the Papal States and sacked Rome. Pius IX suspended the Council in 1870, though it was not yet formally closed.
The successors of Pius IX would not reopen the Council for fear that it would be hijacked by enemies of the Church. Pope St. Pius X warned of the growing threat of Modernism and Relativism in the Church, which provoked him to write his decree on Modernism, Lamentabili, the encyclical Pascendi and the Oath Against Modernism.
In 1960 Pope John XXIII officially closed the First Vatican Council. in 1962 he convened the Second Vatican Council. In his opening address the Pope, an optimist, denounced the “prophets of gloom and doom”. Vatican II was supposed to discuss a variety of issues, and the Liturgy was not one of them. Cardinal Montini, the future Pope Paul VI, said that the Council had no reason to discuss Liturgical matters. However the bishops of France, Germany, Belgium and Holland demanded that the Liturgy be added to the proposed agenda. For two years before Vatican II agendas, outlines and orders of business were prepared- only to be thrown out in the first session of the council. John XXIII died soon after- it is said that his last words were “stop the council!”.
Paul VI continued the Council, which produced 16 documents between 1962 and 1965. Not one of these documents contains any solemn definitions that Catholics are required to accept de fide (as an article of the faith). These documents deal with a variety of issues and are generally written with ambiguous language, leading to varying interpretations of the documents and even varying opinions on how the documents must be read. Because of this a vague ideology has emerged that suggests we follow in the “spirit of Vatican II” rather then the letter of Vatican II.
In regards to the Liturgy. The Council’s document on the Liturgy, Sacrosanctum Concilium, is very differant, even contradictory, from the Liturgical reforms that followed the Council. This document contains nothing regarding the position of the Altar, the way to recieve Holy Communion, the de-emphasis of the Mass as a Sacrifice, the abolition of Minor Orders and the Subdiaconate, the removal of statuary and iconography from churches, the removal of side-Altars and communion rails, dancing, folk-music, female Altar servers, lay Eucharistic ministers and lectors, multiple Eucharistic prayers, and many other things that have crept into the modern liturgy. The document did mandate the use of Latin (vernacular was suggested as an option for parts of the Proper Prayers pertaining to the congregation- Latin was to be kept for the Ordinary of the Mass, especially the Canon/Eucharistic Prayer), Gregorian Chant was reffered to as the Church’s greatest treasure and especially suited for the Liturgy. Sacrosanctum Concilium contained nothing that could remotely suggest the creation of a New Roman Rite.
