Paul's epistle to the Romans is one of the most beloved writings in the entire biblical canon, especially for Augustinians and Protestants. It is the subject of thousands of commentaries, many by the most important doctors of the church: Augustine, Aquinas, Luther, Calvin, Hodge, and Barth, to name a few. It offers the doctrines of sin, the gospel, and salvation in a nutshell. It is the basis for the structure of the first Protestant textbook in what later came to be categorized as systematic theology, Philip Melanchthon's Loci Communes (1521). It is a frequently-cited sourcebook of the Reformation solas, which teach that salvation comes by grace alone through faith alone because of the work of God through Christ alone. It is the site of the "Romans road" a standard tool for sharing the gospel used by myriad evangelists in the evangelical movement. It is a central text of scripture, in short, employed by many readers as a key to the whole Bible. Jonathan Edwards never published a major commentary on Romans. He did, however, preach about and write about Romans at numerous times throughout his life. Though he is highly regarded today as a great literary artist, natural scientist, philosopher and psychologist of religion, he was chiefly a biblical thinker, a minister of the Word. And inasmuch as he remains one of the most important thought leaders in all of Christian history, this new work, bringing together a major collection of his writings on the biblical book of Romans, will be a welcome one for many.
