I read your article, and it's nice that you're pleased about WCG's re-branding as Grace Communion International. But if this is cause to make the Christian world rejoice, then there's something terribly wrong. The WCG transformation is more a travesty than a miracle. That's why a lot of the people in the WCG who originally welcomed the "reformation" are now ex-members. Outside commentators like yourself have too often avoided asking the tough questions in their haste to claim a victory for evangelical faith. That's why your blog entry is naive and, frankly, uninformed.
When the changes began, people like you were needed to help guide the beneficiaries of Armstrong's Empire away from a hierarchic mindset. What happened? Nothing. Sure, there has been doctrinal change, and that was hugely necessary. But it wasn't enough.
Richard, if you're serious about helping the newly re-christened GCI and its members, write to Joe Tkach and urge him to introduce genuine accountability into his church (and I do mean his church... which is why accountability is desperately needed.) Encourage him to establish an elected board and a procedure whereby the church president must be selected by a representative body for a set term of office. Familiarise him with the concept of mandated leadership.
If you can pull off that trick, then you'll be able to write about a real miracle, with no argument from me!
