Well, there's no reason why anyone should be interested in Anglican opinions. But, for what it's worth, I have enthusiastically signed that petition. I am not an integralist but a gradualist; little moves in the right direction are, to my simple mind, a good thing; little moves in the wrong direction are a bad thing.
But I have to say - sorry if this is a breaking of ranks - I would find it hard to condemn (exempli gratia) a clarification which gave the Archbishop of Milan control over the Ambrosian Rite. The Ambrosian Rite is not the Roman Rite. The Bishop of Rome has the right to say what the rite of his Church is; so does the Successor of S Ambrose. Even if the b****r gets it wrong.
I would be a trifle less categorical about (exempli gratia) the Dominican Rite. It is, after all, but a dialect of the Roman Rite. On the other hand, S Pius V gave those older dialects of his rite exemption from papal legislation; perhaps they are morally entitled to keep that autonomy. Dunno.
I am perplexed, as one who takes the long view, about the suggestion that bishops might not have an inherent right to confer orders according to the old pontifical. There would be a quaint irony if those 'liberal' bishops all over the world who have been concerting with each other the expression to Rome of their 'concerns' about SP turned out to have achieved ... a restriction upon episcopal independence of action! Additionally, the Pontifical was the last book of the Latin Rite to be rendered uniform. Until well after the invention of printing, bishops were using manuscript ponrtificals inherited from their predecessors which differed quite considerably from each other. Where is the necessity for uniformity?
By coincidence, I had already prepared, and timed to begin on Monday, a series on the post-conciliar Rite for the Consecration of Bishops. I had a go at the Rite of Deaconing a little while ago.
It's all Go, isn't it?
