text: Yes, lack of education when the changes were introduced is a deep cause of a lot of liturgical chaos ever since. But we must remember, that the clergy, most bishops and priests, who then interfaced with the Catholic millions, did not themselves have any deep understanding of the new liturgy. Even today, one would be hard pressed to find a "regular" priest who is competent to explain the rationale of the reform, for that cannot be done properly without a deep knowledge of the history of the liturgy. Not that the content of the explanation must convey that full history, but the educator MUST know it well, if one is to avoid inventing pious explanations for changes rather than the real historical basis of the reform. 
  
  Bluntly put, Christians of the first four centuries from anywhere in the world, would find the modern Roman liturgy to be a comprehensible approximation of their own experience, be that in Syria or Egypt or Byzantium or Rome. What we have is, roughly, a reconstruction.
