In the Catholic Church, preconciliar Latin liturgical rites coexist with postconciliar rites. In the years following the Second Vatican Council, Pope Paul VI initiated significant changes. Some of Paul VI's contemporaries, who considered the changes to be too drastic, obtained from him limited permission for the continued use of the previous Roman Missal. In the years since, the Holy See has granted varying degrees of permission to celebrate the Roman Rite and other Latin rites in the same manner as before the council. The use of preconciliar rites is associated with traditionalist Catholicism.
