The shift from the Traditional Latin Mass to the Novus Ordo was something I experienced personally as a young Catholic. It might have been intended to be well crafted and something for which the laity was well prepared, but it was not, and after that the fallout was swift and it has continued to this day when our politicians now feel free to define what it means to be a Catholic.
Some personal musings on the subject, including how I find myself being drawn more to Tradition as I watch the modernist trends grip both Church and a crumbling social structure.
