The real debate is:
Is knowing that something is coming, while not having an exact date, useful at all?
I say "yes".
Both for the SSPX deal with Rome, as well as the economic collapse. In both cases, there are things I will want to do to prepare. Even if I end up preparing a few years early, it's better than being a few days late.
Of course I would prefer to know EXACTLY the day and the hour. But, barring that, I'd at least like to know what is inevitable, what is coming down the pike.
Certain measures can be taken (for example, looking to my family's spiritual future, providing some means of attending Mass if something happened to our local SSPX chapel. In our case, the next non-Indult Mass option would be 3 1/2 hours one way!)
In the case of preparing for economic collapse, I can begin right away not trusting the banks, storing in the bank ONLY what I need to pay our monthly bills. I can purchase and store some down to earth supplies (gardening tools, chicken raising equipment, etc.) In the current economic setup (fractional reserve banks, fiat currency) economic collapse is a mathematical certainty.
Some (fools) might say: If you don't have a date, then sit down and shut up. Just forget about it. Not having the date, you have NOTHING you can act on.
I disagree. I'll take what I can get.
