People today often ask questions like: “What in the world happened at the time of Vatican II, that the Church seemed in such an unholy hurry to change? Why were the changes so drastic and so sudden? What were the causes, the motives, the expectations, the assumptions about reform and its expected fruits? Who were the main actors? Was it planned out or random? Who benefited (cui bono)? How responsible were the bishops for it, versus the middle managers, versus the laity?” and so forth. It can be very hard to disentangle so many threads.
