N.T. Wright, who is currently working on a massive tome on Paul, to be released “no sooner than 2012,” spoke about unity a lot during the conference at Wheaton. Apparently the overarching theme or argument of his Paul book (the next volume in his magnum opus series that so far includes The New Testament and the People of God, Jesus and the Victory of God, and The Resurrection of the Son of God) is that “the main symbol of Paul’s worldview is the unity of the church.” At various points in the conference he said things like this: “The cross brings together—unthinkably—the slave and the master” (talking about Philemon); “The cross is the place where the unreconcilable can be reconciled;” “The unity of the church is a sign to the world that there is a new way of being human;” “The unity of the church sends a message to the world-be rulers of the world that Jesus is Lord and they are not” (Eph. 3); and “Nothing justifies schism.” (Brett expands upon this in a Christianity Today article)
It is interesting that, broadly speaking, the various ecclesial attitudes toward schism are also reflected in their doctrine regarding divorce and remarriage. Only the Catholic Church maintains the biblical ideal of “no divorce and remarriage” albeit with sometimes abused weasling of annulments.
