CHAPTER XX THE MEDIEVAL CHURCH AT ITS HEIGHT Section 83. Organization and Powers of THE Church In the preceding pages it has been necessary to refer con- stantly to the Church and the clergy.

We have already learned something of the rise of the Church and of its head, the Pope, as well as the mode of life and the work of the monks as they spread over Europe.

We must now consider the Medieval Church as a completed institution at the height of its power in the twelfth and thirteenth centuries. 475
