From ‘Peter Leithart on the End of Protestantism‘:
[The claims made by those advancing ‘Reformed Catholicity’ imply] that true catholicity is only realized by Protestants in the twentieth-century onwards, which is (historically speaking) a very small subset. However, to say that true catholicity is realized only by a small subset (as measured historically and not merely geographically) sounds very sectarian to me…. one can argue that ‘Reformed Catholicism’ is super-individualistic because it has never found corporate expression in any ecclesiastical body.
