Many Christians do not believe in astrology, but it is mentioned in a general way quite frequently in the Bible. One of the most famous quotes that astrologers use as to explain that astrology is not evil is:

"There shall be signs in the sun, the moon, and the stars." – (Jesus Christ, Luke 21:25)

Then, of course, there is one of the most famous astrological omens in history – The Star of Bethlehem. The star was supposed to be a sign from God that the Messiah was about to be brought into the world. In 1600, the astronomer Johannes Kepler brought forth the theory that the star was actually a conjunction of Jupiter and Saturn, which looked like one big glowing star.

The conjunction also brought he prediction that a Messiah will be born. This is because Saturn rules the Jews and Jupiter is a symbol of royalty. Astrologically, this was very prodigious for someone who would eventually be called “The King of the Jews.”

Yet another interesting Biblical aspect to astrology is that the twelve signs of Israel are also associated with the Zodiac signs. Jewish temples in holy lands often have the twelve signs of the Zodiac in their temple floors.

There is also support for astrology in the book of Genesis. In Genesis 1:14 -1:15, it is written,

"And God said, ‘Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, and let them be lights in the expanse of the sky to give light on the Earth.’ And it was so." ‘

Another famous astrology reference to do with signs in the sky is in Luke 21:25-27,

"And there shall be signs in the sun, and in the moon, and in the stars; and upon the Earth distress of nations, with perplexity; the sea and the waves roaring; Men's hearts failing them for fear, and for looking after those things which are coming on the Earth: for the powers of heaven shall be shaken. And then shall they see the Son of man coming in a cloud with power and great glory."

The Bible also frequently refers to the Morning Star or the Lightbringer. This is another name for the planet of Venus, which shines brightly as the sun rises.

In Revelations 22:16, Jesus even calls himself the morning star saying,

"I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root and the Offspring of David, and the bright morning star."

No discussion of the Bible’s relationship to astrology would be complete without some reference to the Piscean Age. Jesus was born under the end of the age of Aries (the ram or lamb)

In astrology, each age lasts 2160 years and right now we are at the tail end of the Piscean age. When Jesus found his “fishers of men” that were the twelve disciples, it was beginning of the Age of Pisces. There was the feeding of fishes to hungry people at the Sermon of the Mount and Christians are often called specula, which means little fishes.

Astrology refers to every 2160 years as a new "age," which is a different sign of the zodiac that comes into position to influence the Earth. The Bible describes events that will occur according to the signs of the astrological "ages".

A commonly used symbol in the Christian churches is the "Vesica Piscis," which is Latin for "mouth of the fish". Its shape resembles a fish without a tail and is identical to the Zodiac sign that is often used for Pisces.
