The book of Romans is one of the longest and most significant things written by the Apostle Paul.
We know from Acts 18:1-2 that the church in Rome had existed for some time and was made up of both Jewish and non-Jewish followers.
Roman emperor Claudius expelled all of the Jewish people from Rome, but five years later all those Jews, including many who followed Jesus, were allowed to return.
When they did, they found a church that had become non-Jewish in its customs and practice.
