Why isn't every Christian well versed in astrology?
The Bible IS an astrology book, and if you don't know astrology you are missing out on a whole layer of meaning.
Here are some examples.
Moses came down from the mountain, and found the Israelites (Jews) worshipping a golden bull (yes, it is mistranslated in the modern Bible) and got angry at them worshipping false idols. (Because the earth had moved out of Taurus and into Aries)
A shofar (pron. /ʃoʊˈfɑːr/, from Hebrew:, is an ancient musical horn typically made of a ram's horn, used for Jewish religious purposes. wikipedia
(where is Moses to come down from the mountain and be angry that they are not keeping up with the times?)
Everyone knows of the Jesus Fish
(Iesus came and told everyone that we have moved out of Aries and into Pisces)
The dawning of the age of Aquarius.
What we see here is Precession of the equinoxes.
Taurus ♉ → Aries ♈ → Pisces ♓ → Aquarius ♒
And it is very important in understanding the time and place of Bible stories.
Bethlehem = House of Bread, where Iesus was born
Virgo = House of Bread, when Iesus was born
On December 22nd the sun reaches its lowest point south,
and comes to rest on the southern cross.
The SUN of God dies on the cross.
Three days later the sun moves north.
On December 25th, the SUN of God is born.
Almost every date involving Iesus is an astrological significant date. Christmas, Easter,...
There are so many astrological/astronomy references in the Bible, that astronomy should be a standard class taught in every church.
But it isn't.
In fact, astronomy is considered a tool of the devil.
And good christians are forbade from learning it.
Its like a group of people saying, don't go learn to read yourself, we will read the Bible for you. And we will keep it written in Latin.
