It doesn’t. My concern is that someone not familiar with the term Reformed would think that this was something started by Luther. Not everyone understands that the Reformed body is distinct from Lutheranism. What the author of Reflections of Rome writes about how the Reformed view Rome, it does not necessarily mean that this goes for all those with the Protestant family.
Valid — Lutherans do not fall into the dark pits of Calvinism’s predestination God with his idea of an “elect upper caste”.
