This would be a book for those who believe that what was not mentioned from the 1917 Canon Law was abrogated in the 1983 Canon Law which included the requirement of head coverings. Nevermind what St. Paul stated....
The author, Anna Elissa, glossed over Archbishop Lefebvre and any other persons/groups that fought to keep both the true Mass and the doctrine and traditions that were/are so very important.
She is careful to not offend anyone who is in love with the Vatican II council. Quite frankly, while some of the information was good/helpful, the pandering to the modernists was nauseating.
This is NOT a recommended reading for anyone in the fight against modernism. It is, however, a possible stepping stone for someone attending the Novus Ordo Mass on a regular basis.
