In many ways the book [Saving Calvinism] is trying to argue for a more popular audience things I've said in some more scholarly works, namely, that the Reformed tradition is broader and more variegated than is often reported today, and that we need to recapture something of this in order that we don't end up unnecessarily narrow in our doctrine and in order to keep some perspective.

[Jonathan Edwards] he has to be engaged with on this issue if you're writing about Calvinism as I am in this book.

In the chapter on the nature of the atonement [in the book saving Calvinism] I argue that it is a mistake to think that penal substitution is the only option on the doctrine of atonement.

There is the view I call penal non-substitution, or the penal example view. (It is also called the Governmental View in textbooks of theology.) This is often associated with Arminian theology stemming from the great Dutch jurist Hugo Grotius. However, the view was taken up by [Jonathan] Edwards's disciples in New England, who developed a Calvinistic strand of the doctrine.

The book [Saving Calvinism] argues in each case that the Reformed tradition is broader and deeper than we might think at first glance - not that there are people on the margins of the tradition saying crazy things we should pay attention to, but rather that there are resources within the "mainstream" so to speak, which give us reason to think that the tradition is nowhere near as doctrinally narrow as the so-called "Five Points of Calvinism" might lead one to believe.

We may think that our tradition is exactly the same as it has always been, but that is an illusion.

I recommend Doug Sweeney's recent book [Jonathan] Edwards the Exegete (Oxford University Press, 2015), which is a terrific treatment of the way in which Edwards was steeped in the Bible, so that it shaped the whole of his thinking.
