At First Things, Jordan Hylden reviews the situation before Lambeth Conference:

Unfortunately, there are several factors in play that will make the Lambeth bishops’ task very difficult. Most fundamentally, the bishops will have to confront a theology, held by many of their own members, which places little value on doctrinal unity and scriptural authority and instead exalts near-unbounded freedom and diversity in matters of faith and ethics...  As Rowan Williams recently put it, the crisis is such that Anglicans are no longer sure that they can recognize each others’ ministries, or even that they are speaking the same language of faith.

UPDATE: Jordan has filed further reports and links.
