This book has accessibility to commend it. It most definitely lives up to its name, Paul for Everyone. I read only the portion on Galatians, so that is all my review will entail. His commentary on Galatians is broken up into smaller portions of the text, in which he provides his own translation of the text, followed by a commentary on it. The commentary generally begins with a story and therefore comes across very pastoral. The translation he provides, is itself not the most accurate. But, Wright is purposing to use language that will force us to consider what the text is really saying, rather than allowing the reader to continue seeing it in the same categories and boxes. Thus, Christ is always translated as Messiah.
From Wright's perspective, Paul is writing to the Galatians with this in mind.
The Galatians have been divided over circumcision, and he is writing to silence his accusers. Paul is upset that the one family has been divided over the issue of circumcision (which sometimes entails other aspects of the Law, such as keeping the Jewish assigned days, weeks, months, and years--the Sabbaths and Feasts.) Because his own authority and message has been called into question, he justifies them both, and explains that nothing has been added to it, by God or man.
He continues his argument by recounting the confrontation he had with Peter over this very topic. And then explains to them that their adopting the Law means that they are saying they are no longer trusting that God has accepted them by their faith, but that they now need to do more--keep the Law. And is this what they really think will perfect them, they start with the Spirit and end with the flesh?
He argues against this question by explaining that the promises of God to build a family are promises based on the faith of Abraham, not his circumcision, nor the fuller Law which would come 430 years later. In fact, he argues, that the Law came not as a guarantee to receive the promises God made to Abraham, but to protect His people until they were mature in the faith (through union with Christ by their baptism).
He then wonders with them why they would return to these old ways. That these Jewish days and circumcising were the same for the Jews as their pagan rituals were for them--albeit God-ordained rituals in the case of the Jews.
Then, he reminds them that the Jewish Christians are only demanding circumcision so that the Gentile Christians would continue to look up to them as the inner circle of Christianity. He explains to them that the bondage the Jewish Christians are trying to impose is akin to the bondage of the Law at Sinai. And that, while the Jewish Christians may think they are the seed of Sarah/Isaac and the Gentile Christians are the seed of Hagar/Ishmael, by their commitment to bondage they are actually revealing themselves to be the seed of Hagar/Ishmael and of Sinai, while the Gentile Christians who are resting in their faith are being revealed as the true sons of Sarah/Isaac and the sons of liberty through faith.
By chapter 5, Paul is reminding them obligation to some of the Law (circumcision) means obligation to all of the Law. Therefore, they should not seek to add to what they have in faith. They need to know that neither circumcision nor uncircumcision makes you more Christian, or more united to Christ, but that it is faith working through love. He is so serious about this that he wishes the circumcisors would just castrate/emasculate themselves.
As he moves towards his conclusion, Paul wants them to understand what fruits the flesh produces versus those the Spirit produces. Being in the Spirit, they should restore their brothers gently and bear one another's burdens. This temporary division should not lead them to look for faults in the other party in order to boast in themselves.
Then, he reminds them that a large part of what the Jewish Christians are doing is really only motivated by fear that they themselves will be persecuted. But, Paul needs for them to understand that circumcision nor uncircumcision count for anything, it is being a new creation that matters. And, he, himself, bears the marks of persecution, the marks of Christ, over this very cause.
That is a summary of Galatians according to N.T. Wright and his Paul for Everyone: Galatians commentary. I know there are many more nuances that could be made, and much deeper theology that could be gone over here. But, it was intended for accessibility and a wide audience.
