In this book, Yoseop Ra would like to reveal that Paul sent letters to the Roman church four times. Accordingly, it will be revealed that Romans was not written to convey doctrine; rather, he wrote them to achieve his own purpose. He requested help from the Romans to spread the gospel in gentile regions, even as far as Spain: It seems, however, that his attempt was rejected due to the renewed theology. When this is properly revealed, the actual history and theology that Paul had with the Romans will be revealed. The most important content was that righteousness is obtained by faith in God who raised Jesus Christ from the dead. This was unacceptable to the Romans at the time from a Jewish perspective. Paul had to write four letters to persuade them, reflecting the fact that they did not agree with his arguments. Accordingly, the actual history that Paul had with the Romans is different from what has been known to us today. If Ra's argument is valid, early Christian history will have to be rewritten.
