This book is a disappointment to the serious scholar of the ceremonial traditions of the Roman Catholic Church. While the sections on current etiquette and papal knighthoods are rather handy (at least if you're planning to have dinner with an Archbishop anytime soon), the large section on clerical dress is inaccurate beyond belief, particularly when it is realized that the author had been a seminarian who studied in Rome. Besides a lack of knowledge of pre-Vatican II usages, there is a certain tone of disdain or impatience taken toward them that this reviewer, an experienced Master of Ceremonies at two churches that offer the traditional Latin Mass with full approval from Rome, does not consider to be a very "catholic" attitude in any sense. Much more useful, fully accurate information on Catholic clerical dress, insignia, and ceremonial will be found in the classic and easily-found (though out-of-print) manuals of Nainfa and McCloud, and the rare (but well worth it) "Ius Pontificalium" of Mgr Nabuco. To sum up, this item will be an expensive, pretentious, mostly misinformative waste of money for the average reader who wants to know more about the externals of Catholic worship and protocol.
