Historical context
Paul wrote Romans from Corinth, one of the most important commercial cities in the empire. Rome had a Jewish population of around 50,000. The letter addresses real tensions between Jewish believers with centuries of Torah tradition and Gentile believers with no such background. Emperor Nero was on the throne. Within ten years he would execute both Paul and Peter.
The people who first heard this word were not reading a book — they were living through empires, oppression, exile, and covenant. Every word carried the weight of that reality. Understanding it changes how you read Scripture.
