OK. If you want to go there, what about the infallibility of the pope and the assumption of Mary?
Were those doctrines heard of in the early church?
Were they not established as doctrine in Vatican 1 and 2?
And isn't a faithful Catholic now required to believe in the immaculate conception, the perpetual virginity of Mary, and her assumption?
I predict that a YES/NO answer will not be forthcoming.

A common mistake. Church teachings do not originate with the declarations of church councils. These declarations--an exercise of the Extraordinary Magisterium--are only made to clarify what the Church has always believed and taught--the Ordinary Magisterium. You would not hold that the Catholic Church only condemned contraception since 1968 (Humanae Vitae) or taught that only men can be ordained to the priesthood since 1994 (Ordinatio Sacerdotalis), would you? The infallibility of the popes and the Assumption of Mary were part of the ordinary day-to-day teaching of the Church long before the declarations of Vatican I & II.
