Who said that it was prudential judgment?
since its about science and nothing to do with faith or morals
Who said it has nothing to do with faith or morals?
the Pope made it a moral case by saying we all have a moral obligation to fight CC
I think you are thinking of this paragraph: “Humanity is called to recognize the need for changes of lifestyle, production and consumption, in order to combat this warming or at least the human causes which produce or aggravate it.” Laudato Si 23.
Yet, that makes me think about the argument against contraception, for example, and the appeal to infallibility in this case.
Who appealed to infallibility in the contraception case?
How can the Church infallibly proclaim against contraception, since it has nothing to do with Faith or Morals?
It does have to do with faith and morals. Sex is an action, and all actions need to be evaluated from a moral perspective.
Contraception has to do with sex, sex is biology, and biology is science.
It also has to do with action, and actions are either good or bad, and good or bad is moral or immoral.
The technology of condoms and pills are also science.
Using this technology is also an action and needs to be evaluated as such.
Isnt the RCC merely making prudential judgements here and perhaps even stepping outside of its bounds by talking about matters of science in this case as well?
The RCC isn’t merely making prudential judgments in either case. Laudato Si repeats the traditional Catholic doctrine that humans must take good care of the earth: “Christians in their turn [must] realize that their responsibility within creation, and their duty towards nature and the Creator, are an essential part of their faith.” (Laudato Si 64)
The document notes that recent science gives us an additional reason to take good care of the earth: “A very solid scientific consensus indicates that we are presently witnessing a disturbing warming of the climatic system.” (Laudato Si 23)
The document also says that the Church is not pronouncing on science: “[T]he Church does not presume to settle scientific questions or to replace politics.” (Laudato Si 188)
The document does repeat that mankind has a moral responsibility to take care of the earth: “[Humanity] also has the duty to protect the earth and to ensure its fruitfulness for coming generations.” (Laudato Si 67)
