A portion of this article is reprinted from an earlier post. The Full Moon eclipse later this month is the last of a relatively rare event known as a “Tetrad,” a series of four total lunar eclipses in a row. While eclipses are not uncommon (we typically see two pairs of eclipses each year although there is often deviation from that pattern), total eclipses are less common and a series of four total lunar eclipses in a row is even more rare.
The first eclipse in this series took place April 14-15 2014, the second on October 7-8 2014, the third on April 4 2015. The final in the series of four will occur on September 27-28, 2015.
In the total eclipse the Moon often seems to glow with an eerie red color, inspiring the name “Blood Moon.” An ancient Biblical prophecy in the Book of Joel says that “The sun shall be turned to darkness, and the moon to blood, before the great and terrible day of the Lord comes.” Some Biblical prophecists (is that a word?) have looked at lunar tetrads and their relationship to Jewish holidays as being significant event for the Jewish people, and because this first “blood moon” falls on Passover, these writers propose that the tetrads of 2014-2015 will have great significance for Israel and consequently, lead to the return of Christ.
However, Passover always falls on a Full Moon, and a total eclipse can only happen on a Full Moon so the correlation is not that unlikely.
This article makes some interesting connections, and then disputes them:
Even rarer is a phenomenon that Mark Biltz discovered. Of the 87 tetrads that have occurred since the time of Christ, only 8 have fallen on Jewish […]
