Catholics often seem to labor under the assumption that during the Second Vatican Council, some honest prelates made some serious but well-meaning errors when making the changes to the Mass that the council called for. They believe that the changes just need a little tweaking. In reality, the demolition of the Roman Liturgy was deliberate and systematic. The fastest way to understand that the Mass changes were entirely intentional is to learn of the life work of one Annibale Bugnini, a priest and later Archbishop who was involved in just about all the major changes to the Latin liturgy in the 20th century.
