When ruling out transformation as part of justification, he gives his best short summary:
‘Justification’ is the declaration of the one God, on the basis of the death of Jesus: this really is my adopted child, a member of Abraham’s covenant family, whose sins are forgiven. And that declaration, in the present, anticipates exactly the final verdict which can also be described as ‘adoption’…. Whichever way you look at justification, whichever Pauline context you line up beside it, it always retains this character: the ultimate future brought forward into the present, and the two have joined hands by the spirit. (Paul and the Faithfulness of God, 958-59)
My only beef with that, in light of my larger project, is that Paul so directly connects justification with new life, that the new life is not just at the resurrection but starts now. So, while justification is a new status it is also eschatological life–both now and the future. It is not based on works, but the life given now is the ability to love and serve God through the Spirit as God’s new creation act in us, that is through his justification of us. And, with Wright, this justification will ultimately entail resurrection from the dead.
