Too much blog reading has caused many acquaintances to fall into hysterical fits concerning Church teaching and contemporary prelates. Things were far worse in the fourth century and in the time of Honorius I. It seems to me that people should spend less time on the Web and more time reading works written before 1700. If you must use the Web, the best short discussions of Church and papal authority I know of are available through downloads that are linked from the Post-Reformation Digital Library. See Dominic Banez, In II-II, q. 1, art. 10, dub. 2 (in Venice 1587, 183-212); Salmanticenses, Cursus Theologicus, tract. 17, disp. 4, dub. 1 (in Paris, 1879, vol. 11, 247-261). Incidentally, Banez, pp. 194-196, explains clearly the errors of today's sedevacantists. Banez is here: http://www.prdl.org/author_view.php?a_id=651 and the Salmanticenses here: http://www.prdl.org/author_view.php?a_id=2122 . If you must use the Web, use the PRDL!
