This theological treatise was written by Augustine in response to questions posed by his friend Marcellinus. Grounded in the Apostle Paul's words, "the letter kills, but the Spirit gives life," the work explores the fundamental distinction between the written law (the letter) and the working of the Holy Spirit. Augustine argues that the law, by merely commanding righteousness, only makes humans aware of their sinfulness without giving them the power to fulfill it. To love and keep God's commandments, humans require divine grace (gratia) poured into their hearts by the Holy Spirit. The discussion extends to the relationship between human free will and divine grace, demonstrating that faith leads to grace, which in turn enables the fulfillment of the law. Ultimately, the work presents a defining theological vision wherein humanity is justified not by its own efforts, but solely through the unmerited grace of God.
