Acknowledgments
Historical background and matters relating to the authorship, date, setting, and structure of Romans have been informed through the study of Scripture together with the work of many respected scholars, including Joseph A. Fitzmyer, Douglas J. Moo, Thomas R. Schreiner, F. F. Bruce, C. E. B. Cranfield, and others.
While these works have served as valuable research resources, the organization, synthesis, explanations, and interpretations presented in this commentary are my own and are offered with the sincere desire to faithfully represent the teaching of Scripture. Readers are encouraged to test every conclusion against the Scriptures themselves, following the example of the Bereans, who “received the word with all eagerness, examining the Scriptures daily to see if these things were so” (Acts 17:11).
If this commentary helps the reader understand God’s Word more clearly, then all glory belongs to God alone.
Among all the books of the New Testament, Paul’s Letter to the Romans has often been regarded as the clearest and most comprehensive explanation of the gospel of Jesus Christ. While each of Paul’s letters was written to address specific people, churches, and circumstances, Romans occupies a unique place because it carefully explains the message of salvation and demonstrates how God’s redemptive plan has unfolded throughout history.
For nearly two thousand years Christians have turned to Romans to better understand subjects such as sin, grace, justification by faith, sanctification, the work of the Holy Spirit, Israel, election, and the practical Christian life. It has profoundly influenced many of the Church’s greatest theologians and reformers, yet it has also become one of the most debated books of Scripture. Entire theological systems have been built upon certain passages within Romans, particularly chapters 8 through 11, often leading sincere believers to arrive at very different conclusions concerning God’s sovereignty, election, predestination, and the relationship between Jews and Gentiles.
For that reason, Romans deserves to be approached carefully. It should not be read as though it were merely a collection of isolated theological statements. Rather, it is a carefully constructed letter whose arguments build progressively upon one another. To remove individual verses from their historical, grammatical, or literary context is to risk misunderstanding Paul’s intended message.
One of the greatest dangers when studying Romans is beginning with theological conclusions rather than allowing Paul’s argument to develop naturally. Many readers approach the letter already convinced of a particular doctrinal system and unconsciously interpret Paul’s words through that system. Instead of allowing Romans to shape their theology, they allow their theology to shape Romans. Every Christian, regardless of theological background, must guard against this tendency.
The purpose of this study is therefore not simply to explain what various commentators have written about Romans, nor to defend a predetermined theological position, but rather to understand Paul’s message as it would have been understood by his original audience. Only after first understanding what Paul intended to communicate can we properly apply his teaching to ourselves today.
This requires more than reading Romans in isolation. Paul frequently assumes that his readers already understand the history of Israel, the promises given to Abraham, the Law of Moses, the Prophets, and the events surrounding the life, death, resurrection, and ascension of Jesus Christ. Throughout the letter he quotes or alludes to the Old Testament dozens of times, often expecting his readers to recognize the larger historical context behind the passages he cites. Likewise, many of the theological terms Paul uses—such as righteousness, justification, faith, election, adoption, redemption, reconciliation, and sanctification—are developed more fully elsewhere in his writings. Reading Romans alongside books such as Galatians, 1 and 2 Corinthians, Acts, and the Old Testament greatly enriches our understanding of Paul’s message.
Understanding the historical setting of Romans is equally important. Paul did not write this letter as an abstract theological treatise disconnected from real life. He wrote to a real church living in the capital of the Roman Empire—a church composed of both Jewish and Gentile believers who were learning how to live together as one body in Christ. They faced questions concerning the Law, circumcision, Israel, the Gentiles, Christian liberty, and the practical outworking of the gospel. Much of Paul’s teaching in Romans addresses these very circumstances. Ignoring that historical background can easily lead modern readers to impose questions upon the text that Paul was never attempting to answer.
At the same time, Romans reaches far beyond the immediate circumstances of the Roman church. Paul’s explanation of the gospel reveals God’s eternal purpose of redemption—a purpose that began long before Abraham, continued through the nation of Israel, reached its fulfillment in Jesus Christ, and now extends to every nation through the preaching of the gospel. Throughout the letter Paul repeatedly demonstrates that God’s plan has always been consistent with His promises and with His righteous character.
As we study Romans, we should therefore remember that Paul is not merely presenting isolated doctrines. He is explaining how the whole of Scripture fits together. Creation, the Fall, the promises to Abraham, the giving of the Law, the history of Israel, the coming of Christ, justification by faith, the inclusion of the Gentiles, and God’s future purposes for Israel all form part of one continuous story of redemption. Romans helps us understand how these pieces fit together.
Throughout this study we will therefore seek to follow Paul’s argument as it unfolds naturally, allowing Scripture to interpret Scripture and resisting the temptation to isolate verses from their broader context. Where historical background clarifies Paul’s meaning, it will be examined. Where Old Testament passages illuminate his arguments, they will be considered. Where difficult theological questions arise, they will be examined carefully in light of the whole counsel of God rather than by appealing to isolated proof texts.
The goal is not merely to understand the Book of Romans intellectually, but to better understand the God who inspired it. The more clearly we understand God’s revealed character, His promises, and His redemptive purposes, the more faithfully we can interpret His Word and apply it to our lives. Romans is therefore not simply a theological masterpiece; it is a testimony to the righteousness, wisdom, faithfulness, and grace of God revealed through Jesus Christ.
Historical Background: Rome, the Roman Church, and the World into Which Paul Wrote
To properly understand Paul’s Letter to the Romans, we must first understand the world in which it was written. Every biblical book was written to real people living in real places under real historical circumstances. Romans is no exception. While the theological truths contained within the letter are timeless, Paul’s message was first addressed to believers living in the capital city of the greatest empire the world had yet known. Their historical setting shaped many of the questions Paul answered throughout the letter and helps us better understand his arguments.
Rome: The Center of the Ancient World
By the middle of the first century A.D., Rome had become the political, military, and economic center of the known world. What had begun centuries earlier as a small settlement on the banks of the Tiber River had grown into the capital of an empire stretching from Britain in the northwest to the Middle East in the east, and from northern Africa to much of continental Europe.
The famous Roman roads connected virtually every province to the capital, allowing armies, merchants, government officials, and travelers to move throughout the empire with remarkable speed for the ancient world. Goods, cultures, languages, philosophies, and religions all converged upon Rome. It truly was the crossroads of the Mediterranean world.
Because of Rome’s strategic position, ideas spread rapidly from the capital to the surrounding provinces. This would later prove significant for the spread of Christianity. A thriving church in Rome had the potential to influence believers throughout the entire empire.
Rome Under Nero
Paul wrote Romans during the reign of Emperor Nero (A.D. 54–68). Although Nero would later become infamous for his cruelty and for violently persecuting Christians, Romans was written during the early years of his reign, before those persecutions began. This historical setting helps explain why Paul could write concerning civil government: Romans 13:1: “Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God“.
At the time Paul wrote these words, Rome was experiencing relative political stability. The severe persecution associated with Nero had not yet begun. Paul therefore instructs Christians to live as responsible citizens, respecting governing authorities while recognizing that all earthly authority ultimately exists under God’s sovereign rule.
The Jewish Community in Rome
Long before Christianity arrived, Rome already possessed a large and well-established Jewish population. Many Jews had first been brought to Rome as prisoners following Pompey’s conquest of Jerusalem in 63 B.C. Others later came voluntarily as merchants, craftsmen, businessmen, and traders seeking economic opportunities within the empire. Over time the Jewish population grew considerably. By the first century there may have been as many as fifty thousand Jews living in Rome, organized into numerous synagogues throughout the city.
Although they lived hundreds of miles from Jerusalem, the Jews of Rome maintained strong ties with their homeland. They regularly traveled to Jerusalem for the great feasts, supported the Temple financially, and carefully preserved their religious traditions. Their synagogues became important centers for worship, education, and community life. This large Jewish presence would later play a crucial role in the development of the Christian church in Rome.
How Christianity Came to Rome
One of the most interesting facts about the Roman church is that Scripture never identifies an apostle as its founder. Unlike churches in Corinth, Ephesus, Philippi, or Thessalonica, the New Testament nowhere states that Peter, Paul, or any other apostle established the church in Rome. Instead, the evidence suggests that Christianity arrived through ordinary believers. Acts records that among those present on the Day of Pentecost were visitors from Rome, Acts 2:10–11: “…visitors from Rome, both Jews and proselytes…“
Many scholars believe that some of these Jewish pilgrims and Gentile converts embraced the gospel after Peter’s sermon and later returned to Rome carrying the message of Christ with them. If so, the Roman church was not planted through a formal missionary journey but grew naturally through faithful believers sharing the gospel wherever God had placed them. This reminds us that the spread of Christianity has never depended solely upon famous preachers or apostles. Throughout history, God has often used ordinary believers who faithfully proclaimed Christ in their homes, workplaces, and communities.
Peter and the Roman Church
Church tradition later associated Peter closely with Rome, and there is good historical reason to believe that Peter was eventually martyred there. However, there is very little evidence that Peter actually founded the Roman church. Paul’s own letter strongly suggests otherwise. Near the end of Romans Paul writes of his desire to preach the gospel where Christ had not already been named, Romans 15:20: “…thus I make it my ambition to preach the gospel, not where Christ has already been named, lest I build on someone else’s foundation“.
If Peter had already established the church in Rome and was actively leading it, Paul’s statement would be difficult to explain. Throughout his ministry Paul consistently respected the ministries of the other apostles and avoided building upon foundations they had already established. Instead, Romans reads like a letter introducing himself to a church he had not founded but hoped soon to visit.
The Expulsion Under Claudius
An important historical event helps explain the makeup of the Roman church. Around A.D. 49 Emperor Claudius ordered the Jews to leave Rome. Luke briefly records this event, Acts 18:2: “…because Claudius had commanded all the Jews to leave Rome“. Among those affected were Aquila and Priscilla, whom Paul later met in Corinth.
Although historians continue to debate the precise reasons for Claudius’ decree, many believe it resulted from disputes within the Jewish community concerning Jesus as the Messiah. Jewish believers and unbelieving Jews were likely engaged in heated disagreements that attracted the attention of Roman authorities. When Claudius died several years later, the Jews were permitted to return to Rome. By that time, however, the Christian church had changed considerably.
During the Jews’ absence, Gentile believers had naturally assumed greater leadership within the church. When Jewish Christians returned, they found congregations whose customs and practices differed from those they had previously known. Questions concerning the Law, circumcision, dietary restrictions, holy days, and Jewish customs naturally arose. Understanding this historical background explains much of what Paul later addresses throughout Romans.
A Church of Jews and Gentiles
The Roman church therefore consisted of both Jewish and Gentile believers. This mixed congregation forms the backdrop for many of Paul’s arguments. Throughout Romans Paul repeatedly emphasizes that salvation comes through faith in Jesus Christ alone.
- Both Jew and Gentile stand equally guilty before God.
- Both are justified by grace through faith.
- Both belong to the same family of God.
- Neither group possesses grounds for boasting over the other.
At the same time, Paul carefully maintains God’s continuing faithfulness to His covenant promises made to Israel. These themes become especially important in Romans chapters 9–11, where Paul addresses the difficult questions surrounding Israel’s present unbelief and God’s future purposes for His covenant people.
Why This Background Matters
Understanding the historical circumstances of the Roman church prevents us from reading Romans as though it were written primarily to answer modern theological debates. Paul was writing to believers struggling with questions arising from the relationship between Jews and Gentiles within God’s redemptive plan. He explains justification by faith not merely as an abstract doctrine but as the foundation upon which Jews and Gentiles alike are united into one body in Christ.
Recognizing this historical setting does not diminish the timeless theological truths found in Romans. Rather, it allows us to appreciate how those truths first addressed the real needs of the believers living in Rome before continuing to instruct Christians throughout every generation. As we proceed through Romans, we should therefore keep this historical picture firmly in mind. Paul’s arguments did not arise in a vacuum. They were rooted in God’s unfolding plan of redemption as it was being worked out among real people living in the heart of the Roman Empire.
