"Provable"??
Again, this is the
Religion forum... "proof" is not an ingredient in this particular pudding any more than "liburruls" is. This particular cherrypicked detail was a minor aspect of the point of one religion co-opting the existing practices of a previous, based on parallels exhibited by historical empirical observation.
There's no reason to get defensive; 'proof' is neither possible nor expected in these matters. That's why we call it "faith". Again, this is not the politics forum; we're not quoting some politician here. There is no "film at 11". Still, certain practices, certain aspects of gods, certain mystic philosophies, obviously have their forebears to which they owe a great creative debt, and the family resemblance is obvious. The evolution of Lupercalia and related fertility rites into the mythical "St. Valentine" being the example here. The association of sex and fertility is the constant; the names of the characters and the character of the characters is the only thing changed, but the origin is common to both/all.
What I present in these threads is a window to those ancient historical roots. The same window that's had heavy curtains pulled over it, even on pain of torture and death, by the same institution that co-opted them. Whether that correlation is accepted or not is ultimately up to the reader. Truth will out, but only if allowed to breathe.
