Have a look at Jim's article on the Comment is Free section of the Guardian's Web site:
As archbishop, Williams might feel that the proper execution of his office requires that he puts aside his personal convictions. Juggling numerous concerns and multiple constituencies, he may have reason not to speak out boldly on behalf of one marginalised audience for fear of alienating another. Equipped with a variety of subtle ways to move the Anglican Communion toward a fuller understanding of human sexuality, he can initiate imperceptible advances on one front while publicly taking a hard line on the other. There are wheels within wheels, and he can make them all spin. He is the Archbishop of Canterbury.
But I am not. And neither are you. We can either speak our truth - which as it turns out is also his truth (and more important, we believe, His truth) and organize ourselves to reform the Churches we love, or we can sit back, beg our gay and lesbian brothers and sisters to be patient, and hope that somehow the Communion will arrive at a new consensus on homosexuality without anyone seeming to have so much as nudged it in that direction.
