Also, and this is a bit of a digression, what teachings of Vatican II should we try to recapture for the Traditional cause?
Perhaps another thread should be started for that topic, where we can look at specific passages and discuss how they can be interpreted in harmony with tradition ... but for starters, I would note some of the "trouble" passages of Vatican II that are so often used by the liberals to promote their cause.
For example, when Lumen Gentium says that the Church of Christ "subsists in" the Catholic Church, we cannot let the liberals say that this means the Church of Christ is a larger entity than the Catholic Church, and embraces all the churches.
Rather, we should be interpreting that in light of Pius XII's statement that the Church of Christ "is" the Catholic Church, and proceed with Lumen Gentium under that understanding.
"Subsists", by the way, is a very specific term. It refers to something that exists autonomously, of itself; the Church of Christ subsists in the Catholic Church because it is the Catholic Church; but the Church of Christ exists in a contingent, dependent way in other sects - and Lumen Gentium actually goes on to explain what is meant by this.
What the document means is that certain things which belong properly to the Catholic Church also exist in other sects: some Protestant sects have retained the Sacrament of Baptism in a valid way; the Eastern Orthodox have retained true Apostolic Orders, which means they have a valid priesthood and a valid Eucharist; there are other examples.
But these sacraments which belong to the Church of Christ exist in those non-Catholic sects in a dependant way - the Protestants would not have valid baptisms except that they got the sacrament from the Catholic Church, and the sacrament owes its efficacy to the Catholic Church.
In contrast, those same sacraments exist in the Catholic Church in an autonomous way; they subsist in the Catholic Church.
I think the use of the word "subsists" in Lumen Gentium is there in order to affirm the traditional teaching concerning the nature of the Church, while also trying to deal with the strange reality of non-Catholic sects that have valid baptisms, valid priests, a valid Eucharist, etc.
Anyway, like I said, perhaps another thread should be started for this topic.
