Good lord Cog, you basically gave us the same lecture that Carl Sagan did on why religion can't be taken seriously. Because it is unfalsifiable. No one disagrees with you Cog on that point, it's just that, this is a bad thing for your position, not a good thing, lol!
Its also utterly, completely, and without exception irrelevant. The Gospel isn't science. The truths are deeper (when, that is, science can be said to be actually getting at "truth"). Science seeks the mechanics of the physical world, the cause and effect relationships between empirically apprehended phenomena. Religion is about much more fundamental truths; the truths of who we are, why we are here, and the nature of our ultimate destiny. It is Sagan who's scientism cannot be taken seriously because Sagan drove science itself into the realm of religion and attempted to use it to answer questions vastly beyond its analytic or explanatory power.
Moroni's challenge implies both verification and falsifiability, but
not in an empirical sense (and who, pray tell, made empirics the sole legitimate path to knowledge?).
Oh, but of course, this question returns us again to the unverifiable and unfalsifiable assertion of metaphysical naturalism that the material universe is all that exists, doesn't it.
Indeed, that's what this entire argument is really all about, not a falsifiability test for the Church, but a falsifiability test for scientism, materialism, and naturalism.
The face of sin today often wears the mask of tolerance.
