The book of Romans in the Bible was written by the Apostle Paul. This is clearly stated in Romans 1:1, where Paul identifies himself as the author: "Paul, a servant of Christ Jesus, called to be an apostle and set apart for the gospel of God"

. Paul wrote this epistle around AD 57 while he was staying in Corinth, using a scribe named Tertius to transcribe the letter (Romans 16:22). The letter was addressed to the Christian believers in Rome, who were a mix of Jewish and Gentile Christians

. Romans is considered Paul's longest and one of his most significant letters, providing a thorough explanation of Christian doctrine, especially justification by faith in Jesus Christ rather than by the law of Moses

. It played a crucial role in Christian theology and was influential during the Protestant Reformation

. In summary:

• Author: Apostle Paul
• Written: Around AD 57 in Corinth
• Recipient: Christians in Rome (both Jews and Gentiles)
• Purpose: To explain salvation through faith in Jesus Christ and to prepare for Paul's visit to Rome
