I came across a great article on this, written in 1999, relating the war on reproductive rights back to the concept of papal infallibility which Pope Pius IX came up with in 1870.
Some highlights:
"The proponents of papal infallibility could not imagine the population explosion of the last half of this century. We find it hard to believe in those who claim moral leadership, while implacably resisting any serious solutions to the population problem worldwide.Just as its critics had predicted, institutional self-destruction is now well under way. But, as it stands now, the Church cannot change its position on birth control without undermining all of its dogma. The Vatican is now obliged to protect the fundamental doctrine of papal infallibility at all costs."

"In 1964, Pope Paul VI created the Papal Commission on Population and Birth Control. It was a two-part commission, and met from 1964 to 1966. One consisted of 64 lay persons, the other, of 15 clerics, including Pope John Paul II, then a Polish cardinal. Pope Paul gave the Commission only one mission—-to determine how the Church could change its position on birth control without undermining papal authority. After two years of study, the Commission concluded that it was not possible to make this change without undermining papal authority but that the Church should make the change anyway because it was the right thing to do! The lay members voted 60 to 4 for change, and the clerics, 9 to 6 for change. (2) We know this because one or more members released the details without permission to an Italian and a French newspaper. Pope Paul did not act immediately. A minority report was prepared, co-authored by the man who is now Pope John Paul II. In this report he stated:
If it should be declared that contraception is not evil in itself, then we should have to concede frankly that the Holy Spirit had been on the side of the Protestant churches in 1930 (when the encyclical Casti Connubii was promulgated), in 1951 (Pius XII's address to the midwives), and in 1958 (the address delivered before the Society of Hematologists in the year the pope died). It should likewise have to be admitted that for a half century the Spirit failed to protect Pius XI, Pius XII, and a large part of the Catholic hierarchy from a very serious error.
This would mean that the leaders of the Church, acting with extreme imprudence, had condemned thousands of innocent human acts, forbidding, under pain of eternal damnation, a practice which would now be sanctioned. The fact can neither be denied nor ignored that these same acts would now be declared licit on the grounds of principles cited by the Protestants, which popes and bishops have either condemned or at least not approved. "
http://www.population-security.org/STLouis99.htmlIn addition to talking about how the church doesn't oppose birth control and abortion in their own right, but rather continues the crusade against them solely to maintain the pretense of papal infallability, the article discusses the Vatican's role in the creation of the moral majority and its influence in American politics. The situation is incredibly infuriating - they won't do what they themselves feel is morally right because it might jeopardize their position of power.
