The best book to reads EENS by Father Muller. I have read books about Fr. Feeney. What I read, stated that Fr. Feeney had a lawyer. When Fr. Feeney was asked by the Holy See to come, the lawyer said, in writing does it state what reason you are to go to Rome. Answer, no, no reason was given. Lawyer said to Fr. Feeney, they should state, if not than you decide but Rome is to state in Writing the reason. Fr. Feeney stayed home. Excommunication for disobediance? So, IMO after reading of Fr. Feeney's background, and his actions, IMO he was defending the Church! Defending her Dogmas and Doctrines.
What struck me was how the Church Magestrium comes to defining Dogmas and Doctrines. This was answered in the book on archives, "The True Story of the Council, by Cardinal Manning. Wow! Here is the last infallible Council and for Infallibility. Now we have always had infallibility and defined, BUT, cardinal Manning explains how in the last 300 years (1560-1860) dogmas and doctrines were having a misunderstanding by the people, definitions that went wrong with suggestions and misinterpretations. So, he and many bishops and pope Leo XIII saw it very necessary to call this Council. When it was, definitions of infallibility were not changed, but made clearer. And Cardinal Manning states that defining goes so far as what magisterium believes is needed, for the time. Really?! So, this book is very important to read. I myself didn't expect what I was going to read. I thought all definitions were in place, but there is more to know and more to realize.
