In the twentieth century the Reformed tradition was developed in several ways including additional confessions (Barmen, the Belhar Confession, the 1967 Confession of the PC(USA), and so on). It was also significantly augmented by the work of important thinkers like Karl Barth, T. F. Torrance, Jürgen Moltmann, Emil Brunner, Kathryn Tanner, and so on.

The book [Saving Calvinism] argues in each case that the Reformed tradition is broader and deeper than we might think at first glance - not that there are people on the margins of the tradition saying crazy things we should pay attention to, but rather that there are resources within the "mainstream" so to speak, which give us reason to think that the tradition is nowhere near as doctrinally narrow as the so-called "Five Points of Calvinism" might lead one to believe.

[John Calvin's] treatment of the person and work of Christ, of the Holy Spirit in the life of the believer, of prayer and liturgy, of the sacraments, and of the way in which we have an in-built sense of the divine that we suppress to our great sorrow - these are all immense contributions to Christian thought. The same could be said of his commentaries, which are still regularly consulted by biblical critics today.

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 those who have only ever read about [John] Calvin, reading the man himself is an invigorating experience.

Christ's work is a kind of deterrent to us, and a way of upholding the justice of God's divine government of the world.

[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.
