[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.

Jonathan Edwards developed a Calvinistic strand of the doctrine.

The atonement chapter [from the book Saving Calvinism] shows how there are real riches in Reformed theology that most Christians today have no idea about.

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.

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).

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.

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.
