When the Apostle Paul wrote the book of Romans, he wrote in order to introduce himself to the various churches that met in Rome. Having never been in Rome, he actually knew quite a few members of the various churches that met there due to his past travels and was therefore able to use his influence with them to speak into the lives of whole churches. His letter was most likely written just before Paul’s journey to Rome around 58 AD. This letter essentially was an introduction of Paul to the Romans “in preparation for his eventual visit to the church.” (Kostenberger 2009, 523) Due to the fact that the church existed before the letter was written and Paul had not yet made it to Rome he would have had virtually no impact in the founding of the church. It likely came into existence after Pentecost when many Jews were visiting Jerusalem for one of the major feasts or it could have started when any Jew moved to Rome from any of the cities that already had Christians in it. With this being said, the church in Rome likely had a mixture of gentiles and Jews in it. This can be extrapolated from the letter from the letter when looking at the various parts addressing both Jews and Gentiles. This can be seen because it addresses both Jews and Gentiles. Paul calls the gospel the “power of God that brings salvation to everyone who believes: first to the Jew, then to the Gentile.” (Romans 1:16) He also talks about both being sinners (Romans 1-2), and both having the same faith which justifies both Jews and Gentiles (Romans 3-4).
