I am not disagreeing, but providing a little more information. Birth control and celibacy both came up at the Council. St Paul VI decided to reserve these issues for further study, rather than let the Council discuss them. A commission on birth control had been set up by John XXIII, and was expanded by Paul VI, I do not know how celibacy was studied. Vatican 2 ended in 1965, Sacerdotalis Caelibatus was issued in 1967, Humanae Vitae in 1968.
There were faithful Catholics on all sides on both issues among the bishops and probably the cardinals. It was not wrong to hold most of those positions, though the situation changed a bit with the encyclicals. Still, none of those who disagreed with the encyclicals were declared heretics or excommunicated. A couple professors were ‘asked’ not to teach Catholic theology, but they remained in good standing with the Church. Some of the more radical who disagreed left the Church on their own.
I do disagree with your remarks on “the Spirit of Vatican 2.” I remember praying for the Council’s success, so that the Holy Spirit “as in a new Pentecost” would come upon the Church. This was very much a part of the Council, and explains a lot of the best that came after: the transition from a shuttered Church enclosing the “Prisoner of the Vatican”, to an emhasis on evangelization and out reach to others. It was the Holy Spirit who inspired the apostles at the first Pentecost, and the same Holy Spirit who inspired many after the Council. I am not sure who inspires the people who dislike the Spirit and the Council.
