This is at least the second letter that Paul wrote to the Corinthians (there may have been others that are not in the Bible). In this letter, Paul is defending himself against accusations from people who are calling him and his teaching false. As Paul writes, he uses a lot of Roman imagery, in order to connect with the audience who will be reading his words.
In this letter, Paul recaps some of the major themes of Christian belief. He also gives insights into the way he stood ip for himself in a culture where he was criticised for his faith.
Corinth was a coastal city and a part, so there were people off different cultures coming in and out of it on a regular basis. The temple of Aphrodite, the Greek goddess of love, was at the centre of Corinthian life, and its priests dictated many of the values and morals of the city.
