Protestantism rose with the printing press and fell with immersivity. It inhabited one specific form of literacy: in a world where people can no longer read—with attention and depth—you can only have post-Protestants. That there are Christianities focused again on a single form of literacy does not make them Protestant, if the single form is different. It does not make them Catholic either, of course—that is, it makes them bad Catholics.
Maybe the most provocative lines in Ross McCullough, The Body of This Death: Letters from the Last Archbishop of Lancaster. Still processing it.
