OK. You say that the real Church, the mystical and spirtual Body of Christ on earth cannot err. But that becomes meaningless when divorced from the physical temporal Church made up of the Churchmen and the faithful, doesn’t it? At a minimum the statement that doctrines declared by the majorities of Ecumenical Councils (and presumably doctrines from the Pope as well) do not have anything to do with anything would deny the concept of infallibility. If only the mystical, and unobservable, unverifiable, Chuch is infallible, then there is no infallibilty.
The implication of thisis that if you disagree with the current Churchmen you can just declare that the real Church believes something different. I think you are saying the Churchmen only represent the real Church when they speak without error, and apparently that we know they don’t error when they agree with certain interpretations of the Faith. This seems no different than saying that the real Church is only whatever one believes it is.
Also, I don’t understand what you mean by the part I bolded. I hear people say that the VII documents are “ambiguous” (I don’t find them to be) and that they are being misconstrued. But they are being interpreted by the people that wrote them, arent’ they? Did Father Ratzinger, Bishop Wojtyla, and the other Churchmen with prominent roles in writing those documents forget what they meant by the time they became Cardinals and Popes? I think that the Vatican II documents on salvation are pretty clear, and that the Church has made their application pretty clear.
If you believe they are wrong, OK. But the documents mean what they say, and they represent the teaching of the Church.
