An introduction to the Letter to the Romans: a historical-critical guide

This book offers a structured introduction to the Letter to the Romans as a unified theological vision centred on grace, faith, and salvation in Christ. Paul’s message is that the law reveals sin; sin affects all humanity; Christ brings redemption; faith leads to justification; the Spirit transforms life; and love fulfils the law.Chapter One presents justification not as a merely legal category but as a transformative reality of God’s grace. It involves faith, baptism, and union with Christ, and gives meaning to Christian action only insofar as it flows from this relationship. Justification is understood as a universal gift, with faith expressed in love as the foundation of Christian life.Chapter Two develops the Gospel as the power of God, revealing salvation in Christ as participation in divine life through the resurrection. Faith is the means by which salvation is received, while righteousness is interpreted in covenantal rather than legalistic terms. Romans 1:16–17 summarises this dynamic: faith leads to righteousness, and righteousness leads to salvation.Chapter Three examines Romans 3–4, where Paul affirms that all humanity is under sin and presents justification as a free gift of God in Christ. Faith is understood as relational trust (rather than mere doctrinal assent), and Abraham becomes the model of justification prior to the law, demonstrating its primacy over legal structures.Chapter Four presents salvation as a comprehensive transformation: from death to life, from law to grace, and from autonomy to communion with God. Through baptism the Christian faithful enters a new existence grounded in hope, freedom, and participation in divine life.Chapter Five interprets Romans 7–8 as a theological anthropology of human existence under the law. The law reveals sin but cannot heal it; the human person experiences an inner division between the desire for good and the inability to realise it. Only in Christ, through the Spirit, is this condition overcome, moving from conflict to liberation and new life.Chapter Six interprets Romans 9–11 as a theology of salvation history, affirming both God’s fidelity to Israel and the inclusion of the Gentiles. Salvation is rooted not in human effort but in divine grace. Faith is presented as a transformative relationship with Christ that reshapes life and thought, and resists any form of legalism, revealing salvation history as an unfolding mystery.Chapter Seven presents Romans 12–15 as a vision of Christian life in which faith is the source of moral action. Moral behaviour flows from the renewal of the mind and culminates in a life of “living sacrifice.” Moral norms are no longer external obligations but expressions of a transformed existence in Christ.Chapter Eight synthesises Paul’s theology: sin and salvation are universal realities, faith is central, the Spirit transforms human life, and Christian existence is defined by service, communion, and participation in God’s salvific plan as it unfolds in the Church.The book is best read alongside selected videos (links provided therein), which gradually and accessibly present Paul’s teaching in the Letter to the Romans. The book is written for readers who wish to approach Paul’s thought in a clear and accessible way while also engaging with historical-critical methods of biblical interpretation.The book also includes three scholarly appendices (articles-I-III) on Romans 7:7–25 investigating: (i) the theological divergence between Eastern and Western interpretations of original sin; (ii) a textual-critical study of this biblical text an ; and the development of a new approach to textual-critical analysis of biblical texts; (iii) an analysis of the transition from Jewish to Christian understandings of the Law. These articles offer both concrete case material and methodological tools for readers interested in historical-critical biblical research. Read more
