Why, according to the Catholic Church, did the Reformation happen? Has the Catholic church ever put forth a theological theory or statement as to why the Reformation happened?

Please note....

I'm not asking about how the Reformation happened.

History is what it is.

I want to know whether or not the Roman Catholic Church teaches that the Reformation has any theological significance (i.e. some kind of "Great Apostasy" or prophetic fulfillment) in the grand scheme of salvation history.

Surely the doctrine of Divine Providence can nail down some sort of idea as to why this gigantic occurrence has happened.
The Catholic Encyclopedia actually has a response to the reason for the Reformation:


  The papacy had become the powerful centre of the family of Christian
  nations.  With the ecclesiastical organization fully developed, it
  came to pass that the activities of the governing ecclesiastical
  bodies were no longer confined to the ecclesiastical domain, but
  affected almost every sphere of popular life. Gradually a regrettable
  worldliness manifested itself in many high ecclesiastics. Their chief
  object -- to guide man to his eternal goal-- claimed too seldom their
  attention, and worldly activities became in too many cases the chief
  interest. Many bishops and abbots bore themselves as secular rulers
  rather than as servants of the Church.

While this is just a summary, the same Catholic Encyclopedia also has an extensive and fair representation of other issues that impacted the church during the time prior as well as immediately after the Reformation.
