The book of Romans is not part of the Old Testament. It is actually a book in the New Testament of the Christian Bible. The Old Testament, also known as the Hebrew Bible, contains texts that were written before the birth of Jesus Christ. These texts are sacred in both Judaism and Christianity.
The book of Romans, on the other hand, is a letter written by the Apostle Paul to the Christian community in Rome. It is one of the epistles (letters) in the New Testament and focuses on themes such as salvation, faith, and the righteousness of God. So, while the Old Testament provides the foundation for understanding God’s covenant with Israel, Romans offers insights into the early Christian church and its teachings.
