The online text of Humanae Vitae.
Well worth reading, and for what it's worth, it illustrates brilliantly what the difference between Protestants and Catholics ought to be. That is, Protestants ought to be dedicated to the doctrine of Sola Scriptura to the point where the primary source of evidence for a document on human life ought to be derived from the Scriptures. I'll also admit that it would come fairly close to Humanae Vitae in many areas.
On the flip side, Catholics,with the doctrine (roughly described) as "Scripture plus authority of the Church," would then be free--and ahem required--to produce a document (like Humanae Vitae) that defers extensively to previous documents.
Interestingly, American law used to follow more of the Protestant tradition (with the Constitution being the reference point instead of the Scriptures, of course), but a look at modern legal decisions suggests that we've moved far more to a Catholic view that could be paraphrased as "Constitution plus the historic decisions of the court."
Given, of course, that our justices are not Humanae Vitae-quoting gentlemen like Gino, we of course find that some of the modern rulings are "not exactly" in the mold of Humanae Vitae. It's time to pray, perhaps, for some justices in the historic Protestant mold, or at least get some better Catholics on the bench.
