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.

[John Calvin's] Humanist training makes him an excellent writer. What is more, he is as relevant today as he was 500 years ago.

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

I don't really have a lot of interns, although I do now use Research Assistants to help me compile indexes when that is necessary.

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 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.

The confessions don't speak with one voice. They are more like a cluster of closely-related but distinct voices - a kind of choir, if you like.
