There are constraints on what counts as "Reformed." It's more than a name or a label. It's about belonging to a particular theological stream or tradition, which is shaped in important respects by particular thinkers and their work, particular arguments and ideas, a particular community (especially, particular church communities, denominations, and so on), particular liturgies or ways of worshipping and living out the Christian life, and particular confessions that inform the practices of these communities.

The atonement chapter [from the book Saving Calvinism] shows how there are real riches in Reformed theology that most Christians today have no idea about.

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

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

It is often reported that the Five Points of Calvinism are the conceptual hard-core of Reformed thought. That is very misleading. The Five Points supposedly originate with the Synod of Dort in the early seventeenth century. Yet we find important Reformed leaders who were signatories to that documentation who don't think that limited atonement is the right way to think about the scope of Christ's saving work. How can this be? The answer that recent historical theology has thrown up is that the canons of the Synod don't require adherence to the doctrine of limited atonement.

What I am trying to argue here [Save Calvinism] and in other works before this one is that the Reformed tradition as I have characterized it is much broader and richer than many of us today imagine. It is not just about "Five Points," and it was never just about [John ] Calvin's thought.

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.
