Perhaps the briefest but bestest apologia for the Covenant and the urgency of agreeing to it is found in this Fulcrum published advocacy by Paul Avis, Catholicity Outweighs Autonomy. Here is a stirring excerpt:
"The Covenant is not perfect and it is not completely clear to me how the “consequences” aspect of it will be worked out, if it comes to that. But I don’t think that is the most important thing about the Covenant. The key, for me, is that by subscribing to the Covenant, Anglican churches will signal in a serious way their intention to remain together. They will signal this to themselves, to all the other Anglican churches throughout the world, and to other Christian world communions, who are watching anxiously and do not want to see the Anglican Communion finally fail as a worldwide fellowship of churches. Such a failure would indicate a serious weakening of Christianity and its witness on the world stage. It would also bring grief and heartbreak to millions of Anglican Christians around the globe.
But is the Anglican Covenant asking too much of member churches? Does it fatally compromise the hard-won autonomy of the “provinces”? I think not. “Autonomy” cannot be the first thing that we have to say about ourselves as Anglican churches. I think the attributes of the Church of Christ in the Creed come much higher up: unity, holiness, catholicity and apostolicity."
I look forward to catholic Anglicans who comment here explaining what is wrong with this understanding of catholicity ...
