Calvin, Doctor of the Catholic Church

T. H. L. Parker said this of Calvin:

As I have been writing the book he has more and more taken on the character and stature of a doctor of the Catholic church. A 'Reformer'? Yes, certainly, for it is the office of the doctors of the church to reform the church - and ecclesia semper reformanda. But not just 'Reformer' in its historical sense; not just the first of the Calvinists or the Calvinians or the 'Reformed' or the Presbyterians. Rather, at a time when the western church had become provincial, he was a doctor of the Catholic church.
