Did you notice that Pope Francis, for Sts. Peter and Paul, went back to the ordinary modern pallium which all the metropolitan archbishops wear?
So, in the space of about 10 years we have seen the longish, archeologizing pallium first used by Pope Benedict (probably a creation of Piero Marini).
Not my favorite. Benedict left that one, portentously, on the tomb of Pope Celestine V.
And then Benedict went to a transitional historic pallium.
Francis used that until now.
So, we are back where we started.
I, for one, am glad to see it back. For how long? Who knows. He might get rid of it all together before he resigns at 80.
