Puzzle: What Kind of Substance would not be Believed by Science?

Someone answers religious (Catholic) definitions of substance.

But you are answering for ‘what kind of substance' which suggests you think you are referring to a substance, or what would you be referring to?

If it is utter nonsense, why adopt the view that it can be considered a substance?

Mustn't it be considered potentially a substance to answer the question the way it is phrased?

Aren't you assuming the consequent that it is empirical?
