'Why can't we just settle down into one big family, members of which look at doctrine in different ways; sure, there are doctrines that might be beyond the pale, but I don't see that, for instance, the ordination of women is such that we can't live with our divergent views on it. We all need to grow and learn together.'
But, Dr Williams, the Catholic (and indeed Orthodox) Church doesn't ask what divergent views it can live with. It asks is this the faith that we have received from the Apostles? Is this what our fathers believed? If you can grasp that, then you will understand why we do as we do, say what we say, and believe what we believe, and why we can't live with diversity on issues that impact directly on the Sacraments.
I hope I'm not doing him an injustice; for the sake of fairness to the Archbishop, I should observe that I have not been able to read his whole talk yet, but only extracts. I will try and find time to read it properly after the extremely busy forthcoming weekend.
I've also just discovered that Fr Ray has said almost the same thing!
