I've only read the first 26 pages. It seems a very good analysis of Fr. Celier's book by Paul Chaussee. The views of Fr. Celier are kind of scary, and I'm surprised that he was even ordained in Econe.
There do seem to be correlations between Fr. Celeir's views and the views of Bp. Fellay, (and Fr. Pagliarani?). Hopefully, someone will compare and write up a good analysis of this. I can't quite tell when Paul Chaussee's analysis was written, but it looks to have been when Pope Benedict was still Pope.
The main thing that Mr. Chaussee keeps pointing out is that neo-Modernism isn't really properly understood. Here are a couple of paragraphs from page 26, which are quite insightful:
"THESE ARE WHAT WE CALL VERY DANGEROUS PROPOSALS"
"Because what is dangerous is their effects. These proposals tend to push the superiors of the Society to engage in discussions that will quickly become negotiations where, by nature, one must concede one thing to obtain or preserve another thing deemed preferable. In this case, with interlocutors of bad "faith" - remember what Archbishop Lefebvre said - we have much more to lose than to gain, and because we have nothing to give up, any concession is then a loss. This is proven by all of the agreements of the Ecclesia Dei rallies.
However, this fact escapes most of the faithful who do not understand what neo-Modernism is (an almost incurable disease of the intelligence and soul from which the Pope himself is suffering), they will fantasize about peace, unity and reconciliation, and aspire so much to these "agreements" that they will forget prudence and patience and come to accuse our superiors of lacking diplpmacy, being too demanding or even betraying them by sectarianism! And these "faithful", more impatient than faithful, will abandon the fraternity to join the rallies of the Good Shepherd or Saint Peter who await them with open arms, all abandoning the doctrinal struggle to be at peace with Rome."
