The term “Blood Moon” is a recent religious usage and is not astronomically significant.

Many “prophets” have profited (pun intended) recently with the publication of fiction and “non-fiction” works talking about so-called blood moons as the sign of a coming apocalypse. First of all apocalypse is the Anglicization of the Greek ‘apokalupto’ meaning “reveal” and so unless you are expecting a cosmic revealing of some sort rather than the end of the world (eschaton) you are using the word wrong. 

For whatever reason the first full lunar eclipse of a series of four in a row without a partial eclipse between any of them (called a tetrad) has recently been called a “Blood Moon”. Many people blame trace this to Christian televangelist John Hagee and others who link this particular moon to prophecies regarding the eschaton in the Bible that speak of the sun going black and the moon turning to blood.

It is important to note that constant attempts to predict the end clearly show that people obviously think Jesus was kidding around when he mentioned that “no one knows the day or hour when these things will happen, not even the angels in heaven or the Son himself. Only the Father knows“.

It is also worth noting that the first lunar eclipse of a tetrad is no bloodier than any other full lunar eclipse. Furthermore, using the rules established by some recent so-called prophets which require these BM’s to occur over the Passover season there have been exactly eight BM’s since the resurrection.

1. 162-163 C.E. (Common Era)
2. 795-796 C.E.
3. 842-843 C.E.
4. 860-861 C.E.
5. 1493-1494 C.E.
6. 1949-1950 C.E.
7. 1967-1968 C.E.
8. 2014-2015 C.E.

There have also been countless lunar eclipses (which look exactly the same) in that same period.

The point? Unless the world has ended seven times previously and we have simply not noticed we are being prophetically ‘had’ and should probably focus our Biblical efforts on more productive areas like trying to understand if Jesus was just joking about feeding the poor or if he was actually serious. 

I would also suggest the money you use to purchase books like Hagee’s $12.99 paperback (unsurprisingly a bestseller) could be better spent. Hagee’s book has sold more than 400,000 copies – that means Christians have spent more than $5 million on this…I wonder how much food could be bought and donated to the poor for $5 million?
