"You must read. You must nourish your souls. You must enlighten your spirit. You must enkindle your hearts, your charity. You must inform yourselves! There is a .. book, a very thick book, which was published relatively recently [in English]. It would not be for everybody - Iota Unum. It is not an easy book, but it is a very informative book. Excellent! Archbishop Lefebvre wished ... that it would be the book every seminarian had in his hands" - Fr. Franz Schmidberger
Archbishop Lefebvre had this to say of Iota Unum:
"A book has just appeared, Iota Unum, written by Professor Romano Amerio, who lives in the north of Italy. In my opinion, it is the most perfect book that has been written since the Council on the Council, its consequences, and everything that has been happening in the Church since. He examines every subject with a truly remarkable perfection. I was stupefied to see with what serenity he discusses everything, without the passion of polemics, but with untouchable arguments. I do not see how the current attitudes of Rome can still persist after the appearance of such a book. They are radically, definitively condemned, and with such precision, for he only uses their own texts, citations from Osservatore Romano. The whole is absolutely magnificent.
"One could base an entire course on this book, on the pre-Council, the Council, and post-Council. I assure you that not much is left standing. The Popes take a licking; he is not at all soft on the Popes, but he recounts their deeds, their words, everything. They stand condemned. In his epilogue he shows how the consequence is the dissolution of the Catholic religion. Nothing is left. But he says that since the Church is not going to perish ... there must be a remnant; after all, the good God said that the Church will not perish, therefore there must be a witness or the witness of a remnant that will keep the faith and tradition."
