IT IS AN INTERESTING QUESTION. If John Calvin were alive today, would Calvin be a Calvinist? Oxford reformation scholar, Diarmmaid MacCulloch, doesn’t think so.
“It is a mistake to see predestination as the dominant idea in Calvin’s theology, although for some of his Reformed successors, it seems often to become so. Rather it was part of Calvin’s growing conviction that he must proclaim the all-embracing providence of God in every aspect of human life and experience, so just as affirmation of a double predestination grew in Calvin’s successive remolding of the Institutes, so did his positive and comforting discussion of providence.” 
Oxford church historian, Alister McGrath agrees.
