If this answer is reasoned: "No 'why' can be known or proved by science, therefore it does not exist," this is again the error of Scientism. "Only that which can be known by science exists." This is an demonstrable fallacy and the claim should be exposed as such.
A major obstacle for religion in our culture today is the philosophy of Scientism both among scientists and the public. It's important that we know how to spot it and how to refute it.
At the least we should avoid claiming Scientism is Science and therefore we must choose between Science and Religion. A false choice based on a false premise.
I am not anti science and I suppose you've found the right word, Scientism, to describe what I am anti to.
The over reaching claims of scientists, like the religious leaders, are appalling and so few leaders are really willing to defend their religion against the pseudoscience of today that it seems odd when any do.
Getting back to the subject of this thread....Benedict has made the supernatural the Bible describes subject to scientific definition.
Some sort of creature became human at what point does Benedict say? And is this what the Bible allegorises into Adam being created?
The Bible is the handbook of Christian belief yet so few Christian leaders are willing to make more than a half hearted defence of it.
