Why do I need to make a distinction? One is allowed for only the most extreme measures and one is completely forbidden.
Actually, that’s not quite true. Condoms, birth control pills, etc. are not declared to be intrinsically evil, it is the interpherence with procreation that is “intrinsically vicious” (CASTI CONNUBII, from Pope Pius XI).
But we make exceptions. For example, in 1951 Pope Pius XII said that it was acceptable to use the rhythm method if a couple had a good reason to limit the size of their family (it’s worth noting that his examples of good reasons were a bit more stringent than those used by many Catholics today.
Later, in 1958, Pius XII stated that it was legit for woman to use birth control pills for medical reasons other than contraception. The contraception would then be a side effect, permissible because of double effect.
Pope Paul VI and Pope John Paul II both spoke very strongly on birth control, but some permissiveness remains. See Fr. Serpa’s multiple explanations of exceptions in the Ask an Apologist forum. Even Directive 36 for health care providers, which many Catholics find controversial, is not without foundation from Rome. Pope Paul VI (who promulgated HUMANAE VITAE) gave some specific dispensations for the same theological reasons (HUMANAE VITAE refers to a loving procreative act, rape is an act of violence and terrorism and the Church appears to acknowledge that some right to self defense is appropriate).
Honestly, figuring out what to do to be obedient is the easy part. BEING obedient is the really hard part!
Actually, I agree. If the Pope specifically calls something “evil”, it is clear to me what I
should do. But I still don’t understand how you decide what is optional.
For example, in the post prior to this, you referenced the “Church’s” non-negotiables. But I suspect you were referring to the ‘non-negotiables’ in CAF produced documents. With regards to voting, I can find only one list from Rome, and it contains 9 examples of non negotiables. The CAF list only fully overlaps two. The rest of the CAF’s list is a subset of two more of Rome’s examples.
So, the Church lists nine things which are examples of “moral principles that do not admit of exception, compromise or derogation”, which I take to mean that we are not permitted to ignore them, compromise them, or undermine them in any way.
Further, the Church states that:
“In the face of fundamental and inalienable ethical demands, Christians must recognize that what is at stake is the essence of the moral law, which concerns the integral good of the human person.”
Which I take to mean that compromising actually erodes the society’s legitmacy in the eyes of God, because the document also notes:
The Church recognizes that while democracy is the best expression of the direct participation of citizens in political choices, it succeeds only to the extent that it is based on a correct understanding of the human person.[17] Catholic involvement in political life cannot compromise on this principle, for otherwise the witness of the Christian faith in the world, as well as the unity and interior coherence of the faithful, would be non-existent.
The emphpasis is in the original, and the footnote refers to a teaching from the Second Vatican Council (dogma, not prudential). Notice, again, the words “cannot compromise”.
To me, this is clear. Words like “cannot compromise”, “do not admit of exception, compromise or derogation”, and “what is at stake is the essence of the moral law” seem pretty clear. As is the authority, it is instructions written by our current Pope, approved by our previous Pope, and addressed specifically to me, a lay member of the Church.
But somehow serious Catholics
know that out of a list of 9, only two are really important and two more are partially important. Some ‘know’ it so well, that it isn’t even a question of interpretion, it just is - inarguably Church teaching (see Fix’s post above). However, my quoting instructiosn from the Church on the matter is somehow “personal interpretation”.
As you said, obeying is the hard part, so I am curious how ‘serious Catholics’ shorten the list with such moral certainty.
