Rethinking Christian Character: Virtue as the Future Character of Priests and Rulers of God's New Creation
Format: Paperback
N.T. Wright is author I have been meaning to read for a long time. I've heard a lot about him especially his book "Jesus and the Victory of God" (which is probably next on my list) and I'm an anglophile at heart so I'll give any british writer/theologian a chance. When this book came on sale for the Kindle I immediately got it and I am very thankful I did. Admittedly the book was much more theological and philosophical than full of "practical advice" but it gave me a lot of meat to chew on that I believe will lead to much practical action. Passion that lasts comes more often from knowing deep down something is true. What we believe determines how we act. Anyway, the book does start off a little slow with Wright's talk about Aristotle's view of virtue and the idea of virtue out in the world. They were some good anecdotes demonstrating how virtue is something developed beforehand that reveals itself in difficult situations, ex. one of the pilot who landed the plane in the Hudson river recently, but I wasn't completely drawn in to the book yet. However, I was sucked in once I hit Chapter 3: Priests and Rulers. The eschatological idea that Christians are going to be priests and rulers in the new creation is something that I often completely lose sight of. It's rarely taught in churches I've been too and it was incredibly intriguing to see Wright lay the biblical foundations for it. As he showed how the theme appeared through out the whole of scripture it was another "ah-ha!" moment for me as the Bible came together once again as coherent connected book that I really can trust. Also I learned a lot from Wright's elaborations on the idea that virtue is really just the character of the new humanity. So when God is calling us to act a certain way it is in light of the future, how things will be in the new creation. This really revolutionized the way I think about my character and is incredibly practical and encouraging. Act this way because that's how things are meant to be and will be! Its not just some random rules that God coming up with; it's the character of the new humanity which was ushered in by Jesus. Wright ends the book with a little more practical chapter, The Virtuous Circle, detailing five practices that help us develop virtue: scripture, stories, examples, community, and sacraments. My only criticism is sometimes the book is a little repetitive. Wright really wants to drive home the point that virtue is something that is a choice but its not just about following certain rules. He again and again shows how it is not legalism or spontaneity that is the solution. We make the choice to renew our minds with the scriptures and do what the scriptures command and slowly our character is changed and virtue comes more naturally. While I certainly will remember this he could have shorted a few passages and still had the same effect. In conclusion, if you are looking for a book that will give you great biblical, theological, and philosophical foundations for what you are supposed to do as Christian on earth this is the book for you.

Absolutely superb and greatly needed
Format: Hardcover
I have read quite a few N.T. Wright books, but this one sounds a cry for something that is most needed in the church today and that is Christian character formation. When virtue is spoken in other places it is most often done so from the wrong angle, but Wright gets it right. The whole idea that after we get "saved", we have done all that is needed, besides inviting a few others to come and join us is tackled by N.T. Wright in this book. Wright explains why Christian character matters and how it relates to God's eschatalogical plan of New Creation. Wright deals with virtue and what exactly it is and how to form Christian virtue. According to Wright, we should practice things like doing right, loving, forgiving, turning the other cheek, etc, until such practice becomes second nature. Wright does not leave out the Holy Spirit in the process, but calls us back to Spiritual disciplines. There is no cheap grace or legalism in this book. Somehow Wright has stuck the right balance between the two poles of liscense and legalism. I recommend this book for all Christians.

BIBLICAL AND THEOLOGICAL NAVIGATION THROUGH PARTISAN POLITICS!
We used N. T. "Tom" Wright's book as the sourcebook for our sermon series and Sunday School lessons during the 2016 national election season in the USA. Due to the unprecedented rancor and division in our country, which always overflows into the life of the church, we needed a solid, biblically-based and theologically-sound source to discuss the body politic, and apply biblical principles to it to help our people navigate these troubled waters. It also needed to be truly non-partisan, not just pay lip-service to non-partisanship then let the true partisan colors shine through, as many authors and books seem to do. Wright's being British and many of his illustration also being so really helped make application without raising defenses or starting arguments. His high view of the authority of scripture and the willingness to be convicted and challenged by the Bible rather than attempt to use the Bible to justify political positions was indeed refreshing. Many purchased the book in our congregation, and I found it be to an excellent source to develop sermons and lessons from. We give this the highest recommendation and comment Dr. Wright on his excellent and needed help in this area of our national life.
