Is there a Ground Zero to be found? Did somebody step on some sort of sacred butterfly many years ago and cause a ripple effect through to the current days? Using this theory of course every action taken to correct the original error will cause further ripples. I know that the liturgiologists and the liturgists will all have their own theories here. The theologians will almost turn to the modernist controversies of the early Twentieth century. The philosophers will probably lay the blame at the feet of Aquinas or, if they are being particularly daring, Augustine.
Personally I think our immediate problems probably originated in the Great War and the crisis of faith and growth of general cultural skepticism that ensued. Of course by faith, and some experience, I know that there is a real entity who works day and night across the generations to stop any unity of thought or practice. Starting with an seemingly innocent question in the Garden of Eden his greatest achievement to date has been to make many Church leaders think and teach that such a unity of thought is undesirable. That unchecked or unchallenged dissidence is a good thing in itself. Of course in the details this seems insignificant but in the bigger picture it has led to a free for all.
