Let’s loop back around to the OP. In it, the question was twofold.
The first part of the question was “is it permissible”/“are there any exceptions”?
The answer to that question is: No. Contraception is intrinsically evil. There are no exceptions.
1ke I know what you mean, unfortunately I read what you said.
I do not believe we can find a sentence from a Magisterial document that says anything that comes close to saying “Contraception is intrinsically evil.” (Believe me I have looked).
“Contraception” is a very unhelpful word when we start looking at the true teaching because it is too ambiguous.
The Church’s teaching does NOT refer to anything that can be seen or touched because it is not about
mere use of ABC.
It looks to be about inferred “human acts” not visible “bodily actions.”
Human acts have intent/purpose - and some of them are contraceptive even if there isn’t a pill or condom in sight. (And conversely in rare situations an ABC may be used without this being a contraceptive act).
It is Human acts (whose matter/object is reasonably judged to be contraceptive in nature) that are intinsically evil. There is more to the definition than simply using a condom or taking a pill.
Contraception is intrinsically evil. There are no exceptions.
Only with the above understanding it seems can we understand how the Church has in fact allowed “contraception” exceptions.
How can there be exceptions?
There can be “exceptions” because in some rare cases of ABC use they are not actually contraceptive human acts - even though an ABC was used.
The example is that of Congo Nuns in the 1960s who, due to increasing lawlessness, stayed on in their mission at the risk of being raped. Advice was sought from the Vatican as to whether or not it was acceptable that the Nuns could be advised to take the Pill on an ongoing basis precisely so as to avoid pregnancy if raped at a later date. Approval was given.
I accept that the Pill is reasonably judged to be an abortifacient nowadays.
However that is not the point - in the 1960s the best medical information available to Church authorities at that time considered it to be simply contraceptive.
So here was have a case of the use of ABC precisley to stop conception - yet the Nuns did not commit a contraceptive human act in taking them to avoid pregancy if raped.
The same appears to be the case for professional married female athletes of the same time who took the Pill to avoid menstruation at critical competition event times. I believe this was also considered acceptable until medical opinion deemed the Pill abortifacient.
It is very hard to see how use of a contraceptive could ever be justified in the case of regular healthy, fertile married couples.
However, it would appear acceptable that a condom could be used to prevent passing on HIV to one’s married partner during sex in the infertile phase (or if one is sterile). Some very respected theologians go further and opine that it could be acceptable even outside the fertile phase. The jury is still out on that one so I would presume this practise would be regarded as at least illicit until definitive judgement be forthcoming otherwise from the CDF.
In short, the Church’s definition of a contraceptive act is about more than mere physical contracepting consequences.
