[John] Calvin is often identified with his account of predestination. Yet that appears in the third book of his Institutes, not the first.

For those interested in Reformed thought more broadly, I'd recommend Peter Leithart's recent book on Reformed Catholicism entitled, The End of Protestantism: Pursuing Unity in a Fragmented Church (Brazos Press, 2016), as a thought-provoking and stimulating read that should get us all thinking about the future shape of the Church, wherever we come from.

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.

Sometimes we can lose the wood for the trees. Some specific issues dealt with in the book [Saving Calvinism]: the scope of election (who is saved?); the nature of the atonement (do we have to hold to penal substitution if we're Reformed?); the scope of the atonement (for whom did Christ die?); whether we have to hold to some sort of theological determinism (God ordains all that comes to pass).

The alternative of hypothetical universalism, according to which Christ's work is sufficient for all but efficient only for the elect, was alive and well in early Reformed thought. Moreover - and importantly for our purposes - this view was not regarded as an aberration but as a legitimate position that could be taken within the confessional bounds of Reformed thought. But that means that the Five Points aren't the non-negotiable conceptual core of Calvinism after all.

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

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