At one time the natural law is interpreted to allow torture. At the present time, the natural law is interpreted to forbid torture. If you will give me a list of any and all of the non-infallible doctrines you are talking about, then I can go over each one and answer your question.
May I interject?
I think there are a couple of inherent difficulties in creating a list of “non-infallible doctrines”. The first difficulty, it seems to me, is that the idea of doctrine is a teaching that is
true. Maybe this is purely semantics in the context of your conversation, I don’t know. Regardless, by way of a definition, the CCC states that doctrine is:
“The revealed teachings of Christ which are proclaimed by the fullest extent of the exercise of the authority of the Church’s Magisterium” (p. 875).
It seems important, then, to carefully distinguish between what the clergy
did or
failed to do,
said or even
taught, etc., and what is actually a doctrine or a dogma of the Church. The example of torture you offered is problematic in just this way. Torture was not once a doctrine of the Church that has now been repudiated. I took a quick look at Denzinger (1954 version, my new one is packed away at the moment), and could not find any doctrinal statements about the natural law justifying torturing people. Actually, I could not find anything about using torture. I think this is the first inherent difficulty—the question of doctrine itself, that is, what it means. The
development of doctrine is only a deepening understanding of revelation. It may be that a deepening understanding of revelation results in the Church reaching different conclusions about certain practical judgments, but holding that doctrine may simply be repudiated seems to be an untenantable position. It also seems that the burden of proof is on the person who asserts this. One would have to clearly identify a doctrine of the Church and then identify where the Church later repudiated the doctrine (i.e. using the definition of doctrine above). The statement, “non-infallible doctrines” (i.e. “fallible doctrines”) seems oxymoronic.
The other inherent difficulty with creating a list of “non-infallible doctrines” is predicated on the notion that the Church defines doctrine that it does not hold to be necessarily true. What would be the purpose of doing this? The alternative is that the Church intended to teach the truth in defining a doctrine concerning faith and morals, but erred in doing so.
