Before even replying to your other comments, one question: given that the Dogmatic Constitution "Lumen Gentium" (1964) speaks of Salvation in in a different way, what exactly is your position on the Catholic Church?
I ask this because if you firmly believe that absolutely no other view on what was said in the Fourth Lateran Council is admissible (in particular that there isn't room for any kind of expansion on the subject), then you are likely a Sedevacantist, given that the Universal Church can't proclaim two opposite things to be true if it is inspired by the Holy Spirit.
