Anyway, my own explanation is that she was valid at the time she was chosen but failed later. And so I see for many if not all of the hierarchy visible to us. As to the hierarchy not visible to us I have no opinion. But a great ease will result from realising and saying that hierarchies are not stable but shifting, shifting, all the time, in accordance with God’s and ours changing trends and changing needs. Do people demand constancy? Less and less. Besides, what they demand is not always important. The truth may be more important.
