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.
