Newman's Challenge by Fr. Stanley Jaki

Here's a recommendation for those who wish to engage Newman at the heart of his Catholicity - unapologetic orthodoxy rooted in the supernatural. Buy it for yourself or for a mamby-pamby liberal Catholic you know who trots out Newman to justify their view of the development of doctrine or the crappy implementation to date of Vatican II. Maybe you know an Anglican or Anglo-Catholic who clings tenaciously to the Church of England. They, too, would do well to read this book.
