I found this blog post, The ironies of Catholic traditionalism, while searching for something completely different. And I was particularly struck by this paragraph:
There are many other ironies here, but the most striking – and, I suspect, the most consequential – is that the conservatives who attack Pope Francis in the name of tradition and magisterial authority have been pressed into holding a variation of the doctrine of private judgement. They no longer countenance any form of obsequium religiosum, religious assent or submission, to the ordinary teaching authority of the Pope. Rather, they advise that you withhold assent until you have established to your satisfaction that what he says is in accord with tradition.
Could anything like the modern traditionalist movements (in various Christian communities) ever have happened in the past? Or is the traditionalist movement a rebellion against itself?
