For instance, the notion of non-penal substitution. This idea, found in the work of the nineteenth century Scottish Reformed theologian John McLeod Campbell and based upon his reading of the letter to the Hebrews in particular, is that Christ offers up his life and death as a penitential act on our behalf, rather than as a punishment in our stead.

[ Jonathan] Edwards is one of my heroes. I've learned much from him over the years.

Reading [John] Calvin is a breath of fresh air.

There is no such thing as a stationary tradition. Traditions are always developing, living things.

[John] Calvin is revered as a thinker of immense importance in Reformed thought, Jonathan Edwards could say in his preface to his treatise on Freedom of the Will that he had derived none of his views from the work of Calvin, though he was willing to be called a "Calvinist" for the sake of convention.

[Jonathan] Edwards definitely shows up in the book [Saving Calvinism]. He appears as one of the interlocutors in the chapter on free will, the other being the Southern Presbyterian theologian John Girardeau.

The Reformed tradition at the beginning of the twenty-first century is different as a consequence of this - and different in nontrivial ways. Some may scoff at this, saying that such "developments" don't represent Reformed thought. But by what standard? Perhaps by the Westminster Confession. But this is only one Reformed confession, and it was only ever a subordinate standard.
