The third of Martin Luther’s 1520 treatises, also referred to as A Treatise on Christian Liberty, this work focuses on the topics of justification and total salvation. Boldly, unmistakably, and directly contrasting the teachings of the church, Luther argued for the truth he found in studying the Bible on his own. Introducing, for the first time to many people, the argument for justification through faith alone, he knocked down the idea of being dependent on additional sacraments, penances, and works for salvation.

Martin Luther, full of compassion, grief, disappointment, and frustration, turns away from his entreaties to and debates with church leaders and writes instead to the German political leaders. With extreme clarity, Luther explains in this letter the unbalanced nature and habits of the religious institution - certain at this point that the German people could only be set free from this continual and escalating religious destruction through the intervention of their government.

The Freedom of the Christian was Martin Luther's first public defense of the doctrine of justification by grace through faith on account of Christ alone. Luther's explosive rediscovery of the Gospel of Jesus Christ shattered the Church of Rome's foundation of works, which considered good works a part of salvation instead of a result of it. Here, Luther constructed a rich theology that relies on the full power of the Gospel, which not only grants saving faith but also nurtures that faith through good works done in the freest service.

The Summa Theologica, by Thomas Aquinas, is a fundamental text in Catholic doctrine, a compendium of theology that has been studied and debated since its first publication in the 13th century. Furthermore, it has been widely regarded as one of the classics of Western philosophy, not least because, perhaps for the first time in such a systematic manner, it set out to consider the views of non-Christian figures such as Aristotle, Boethius, Muslim writers including Averroes (Ibn Rushd) and Avicenna (Ibn Sina) and the Sephardic Jewish scholar Maimonides.

Often called Paul’s magnum opus, Romans has been pivotal to Christians’ understanding of salvation for generations. It had a profound influence on Augustine and Luther. Calvin saw it as the key to understanding all of Scripture. In this volume, Dr. R.C. Sproul introduces us to Paul’s fullest, grandest, most comprehensive statement of the gospel and explains why it is just as vital for believers today as it has been for believers throughout history. Verse by verse, Dr. Sproul unfolds the vast truths that Paul has clearly and carefully woven throughout this book.
