Here is something I received via e-mail from "The Apostolic See" (some kook -- I think Pope Augustine?) Anyhow, it has some interesting points, even if "the messenger" isn't normally a worthy source.
There has been much said about December 21, 2012. Today we present another interesting corollary, to fulfill perhaps to the full the potential mystery in this prophecy. For it is written:
“But pray that your flight will not be in the winter, or on a Sabbath. “For then there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will. “Unless those days had been cut short, no life would have been saved; but for the sake of the elect those days will be cut short.
December 21, 2012 is Winter Solstice. December 22, 2012 is the Jєωιѕн Sabbath. In some years Winter Solstice actually occurs on December 22, rather than the 21st. Finally, December 23, 2012 is the Christian Sabbath.
The three days of darkness and the judgment of God then? Do the brethren see how it all seems to come together- the alignment of the sun with the dark rift on December 21, 2012- and this prophecy from Holy Scripture, or is it merely a coincidence? Is it further a coincidence that winter and the Sabbaths combine to form THREE DAYS? (THE THREE DAYS OF DARKNESS PREDICTED BY THE SAINTS?)
Therefore brethren take heed that your flight be on these days- "Pray that your flight will not take place in winter or on the Sabbath,for then [in these days] there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will". (Matthew 24:20-21) There will be no such tribulation ever, such as will occur in those three days of darkness."
Our Lord further declares that those days are cut short for the sake of the elect of God. Short from what? Why, from Christmas day! As it is written:
20But pray ye that your flight be not in the winter [Dec 21, 2012], neither on a sabbath day [Dec 22-23, 2012]: 21For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. 22And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
"except those days should be shortened" there should not a single human survive. Christmas day is the true symbol of new birth and new life. Christmas day is the symbol of light coming into a dark and sinful world. It is upon this day that the three days of darkness should actually end, since Christ Himself is the light. But, due to God's mercy, Christ will cut the tribulation short. The shortening is from Christmas day to Christmas Eve.
Brethren, if Christ were to deal the full brunt of His great wrath, then the beginning of the judgment would be on the cold Winter Solstice Day predicted by the saints until Christmas day itself. Yves Dupont states clearly that the saints predict that the three days of darkness will begin on a cold Winter (i.e. Winter Solstice). But if God were to allow His wrath to remain long upon the earth, not a single man would be saved. If God allowed His tribulation to last until Christmas day, the actual symbol of Christ's light coming to the world, then all men would already be slaughtered. This result would be just, but it would not result in the proclamation of God's mercy.
Therefore, for the elect's sake, Christ will shorten it by one day. So that instead of four days of darkness, it will be only three days of darkness. These days will end on Christmas Eve, rather than Christmas Day. This way, a few men will survive the judgment. The new birth of a holier world united under the Monarchies and Governments formally allegiant to Christ would then begin early.
Thus, the Church calls upon all men to prepare themselves for the Great Tribulation- which if these calculations are correct, will be occurring in just under two years. If these calculations are not correct, then it must be construed as an intriguing coincidence that there are so many alignments in this three day period.
