[quote=ComradeAndrei]It is a clearly infallible teaching in the sense of Pope Paul VI’s use of the Ordinary Magisterium. I think the Church doesn’t formally “declare” it infallible because the Church is hesitant to just declaring everything formally infallible. I think (IMHO) that there are too many details to really be able to stick it down as infallible and to be able to properly treat it without more confusion.
Also, the folks that want to weasle their way around contraception by saying that Pope Paul VIs Humanae Vitae was not an “ex cathedra” statement just want to rationalize their own behaviors and not get in line in humble obedience to the Church’s wisdom on the matter. We don’t need everything officially infallibly declared for us to believe it.
This has been the constant teaching of the Church, the Faith handed down to us by the Apostles through the Popes and Council Fathers!
That’s a great answer…it’s been my understanding that numerous church teachings are infallible through the ordinary magisterium. For example, abstinence from sex prior to marriage is in the ordinary magisterium. There is no need for declaring it infallible because the church has always understood it to be so. Another thing with the teaching against contraception is that nearly every Christian church taught against contraception until the 1930’s. It was simply understood by all Christian religions that contraception was wrong. Now, the Catholic Church is the only one still holding the line (that I know of.) And Pope Paul VI further defined, explored and explained that teaching with Humanae Vitae due to the confusion of the times.
