The problem with Wright is that he has enough truth thrown in to make what he's saying appear orthodox. Was the issue of the Gentiles coming into the kingdom apart from Jewish ritual an important issue to Paul? Of course. Does the Bible say that sanctification is necessary? Of course. Does the Bible teach a judgment according to works? Of course (and it isn't as if all Reformed people say it's merely hypothetical either). But does that mean that the Jews were devoid of legalism and that we're kept in the New Covenant by works? Of course not!!!But Wright admits that these works which we will be judged by are solely brought about by the Spirit. It is not anything that we can do. It is salvation by works, but works of Christ and the Spirit.
