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.

I do think that I have been fortunate to make friendships with other scholars, and form reading groups where ideas are exchanged and papers are read. That is a real boon, and it is something I think every scholar or writer can benefit from.

For instance, there are many mainstream Reformed theologians that deny the doctrine of "limited" atonement (the "L" in TULIP, the acrostic for the Five Points of Calvinism). These are not thinkers on the margins or troublemakers. They are leaders at the center of Reformed thinking like Bishop John Davenant.

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

The best Reformed theology isn't just about careful arguments for theologically sophisticated conclusions. It is about how to live the Christian life.

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.

I think everyone who has an interest in Reformed theology, or just in Christian theology more generally, should read John Calvin Institutes.
