It is good that we have limited spheres of influence. I am not a priest of his diocese, so though I always listen attentively to men in red, I have no need to pay him the slightest heed. Now if Bishop Lang (whose courage we have had cause to mention before, here, etc.) were to say anything, then I would immediately write to him, because he is my Bishop. However I credit Bishop Lang with a more sophisticated and diplomatic appreciation of the faith than others I could mention (he is, after all, the Minister in charge for Foreign Affairs).

Link here. He will have to issue a statement, of course. Those naughty Americans! Standing up for the teaching of the Church and in solidarity with little old us! It would be wrong to give advice to those outside his diocese here in England and Wales, and not to give his advice to those in America.
So I am going to hunt around and dig out a megaphone. He could try the old Jonah trick and preach quietly, hoping that no one makes a fuss.
A megaphone to the waves should do it.
