I don't have all the links to the statements and responses just now as I've been off to the dentist this morning. As it has been noted by various people, there are several key points that await clarification when the apostolic constitution is made public:
-There there be one uniform 'Anglican' liturgy?
-Will married clergy be permitted past the first generation?
-What are the differences between the new structure and existing ones?
And so on. Past posts at this blog do much to lay out the background of today's announcements.
