[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.

How many people in the pews know that [ Jonathan Edwards] is both a founder of evangelicalism and, say, an idealist who denied that the material world exists?

The book [Saving Calvinism] itself is not recommending that we move the borders, so to speak. It is recommending that we look at what lies within the confessional bounds of Reformed thought.

[John Calvin] writes clearly, directly, without artifice, and gets straight to the practical heart of the matter.

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.

Reformed theology belongs to this confessional tradition, and Reformed theologians and churches continue to write confessions even today.

Now, don't get me wrong: I'm not rubbishing penal substitution. But there are other options that have been advocated by Reformed thinkers of the past.
