Hence, you would see no change in DNA or any other scientifically testable properties.

Then the difference -- between a metaphor and a completely undetectable reality -- is essentially semantic.

BTW, I respect Catholics for taking verses like this at face value... but I wish they'd do it for others, like "a bishop, then, must be the husband of one wife."

Not at all. The metaphor is only true in a manner of speaking, that is, according to a certain sense of the word. But transubtantiation is absolutely true, just as you are the very same person you were 15 years ago, even if every atom of your body has been replaced by another atom. How can you be the same person through time, even with replacement of parts? Because your *substance* stays the same.
