I'm read a book about Mother Angelica by Raymond Arroyo
In it she explains how she had her nuns read Vatican II thoroughly -- and what they found changed EWTN.
They found that Vatican II endorsed the Latin Mass -- so Mother changed her programming.
I do think that the US Bishops did not interpret it correctly, but went their own wayward way.
You are onto something important here and that is the major difference between the actual Vatican II and the alleged "spirit of Vatican II." That "spirit of Vatican II" is, of course, what "progressive Catholics" (a contradiction in terms if ever there was one) claimed that the Council fathers really said when the documents said the precise opposite of the "progressive" dream (or nightmare) agenda.
The last 50 years have often been unkind to the Church because of that "progressive" false flag operation blessed by their "father" below.
Mother Angelica is a magnificent servant of God.
May God bless you and yours and all the good work you do here and elsewhere!
