Are you admitting that Calvin may have been wrong in some of his theology? If so, please point out just one part of his theology you think is or may be in error.
Are you trying to tell me that a statement such as "The Gospel is Calvinism and Calvinism is the Gospel" does not equate the two? If so, you need a very basic class in logic.
Equal to and the same as are different things.
Or do you think a man who says "Jane is my wife" is like a man who says "Jane is as good as my wife."
