An interesting collection of essays on various figures from the Reformed tradition beyond that of John Calvin, including Martin Bucer, Theodore Beza, Richard Hooker, George Carleton, John Davenant, and Francis Turretin.
The essay on Davenant argues that the Westminster Confession was not originally designed to preclude those who held to Davenant's form of hypothetical universalism from subscribing to it. I personally remain unconvinced by this argument, though it is important to note that Davenant's hypothetical universalism is a far cry from the Arminian notion of universal atonement.
The essay on Bishop Carleton, who was one of the English delegates at the Synod of Dort, reminds us that there is no incongruity in Anglicans insisting that the Bible is primarily about the salvation of sinners to the glory of God and that a particular form of church government is juro divino, though I disagree with Carleton on the precise form that is of divine right. Carleton argued that church polity was necessary to safeguard the gospel, thus it is a false dichotomy to argue that Christianity is primarily about salvation to the exclusion of matters of church government.
The chapter on Francis Turretin reminds us of the critical importance of natural law to Reformed ethics and political theology. Natural law explains why fallen sinners still perform acts of apparent civic and political virtue, though these acts are not, properly speaking, good works as they are not done to the glory of God.
If you have a Kindle Unlimited account, you may read this collection of articles for free. The only drawback is that the references are compiled in a list of endnotes at the back of the work. Still, each essay has a bibliography at the end, which points you to relevant further reading.
