Question: "What does the Bible say about astrology or the zodiac? Is astrology something a Christian should study?"
Answer: The Bible has much to say about the stars. Most basic to our understanding of the stars is that God created them. They show His power and majesty. The heavens are God’s “handiwork” (Psalm 8:3; 19:1). He has all the stars numbered and named (Psalm 147:4).
The Bible also teaches that God arranged the stars into recognizable groups that we call constellations. The Bible mentions three of these: Orion, the Bear (Ursa Major), and “the crooked serpent” (most likely Draco) in Job 9:9; 26:13; 38:31-32; and Amos 5:8. The same passages also reference the star group Pleiades (the Seven Stars). God is the One Who “fastens the bands” of these constellations; He is the One who brings them forth, “each in its season.” In Job 38:32, God also points to the “Mazzaroth,” usually translated “constellations.” This is thought by many to be a reference to the twelve constellations of the zodiac.
The constellations have been tracked and studied for millennia. The Egyptians and Greeks knew of the zodiac and used it to measure the beginning of spring centuries before Christ. Much has been written of the meaning of the zodiacal constellations, including theories that they comprise an ancient display of God’s redemptive plan. For example, the constellation Leo can be seen as a celestial depiction of the Lion of the Tribe of Judah (Revelation 5:5), and Virgo could be a reminder of the virgin who bore Christ. However, the Bible does not indicate any “hidden meaning” for these or other constellations.
The Bible says that stars, along with the sun and moon, were given for “signs” and “seasons” (Genesis 1:14); that is, they were meant to mark time for us. They are also “signs” in the sense of navigational “indicators,” and all through history men have used the stars to chart their courses around the globe.
God used the stars as an illustration of His promise to give Abraham an innumerable seed (Genesis 15:5). Thus, every time Abraham looked up at the night sky, he had a reminder of God’s faithfulness and goodness. The final judgment of the earth will be accompanied by astronomical events relating to the stars (Isaiah 13:9-10; Joel 3:15; Matthew 24:29).
Astrology is the “interpretation” of an assumed influence the stars (and planets) exert on human destiny. This is a false belief. The royal astrologers of the Babylonian court were put to shame by God’s prophet Daniel (Daniel 1:20) and were powerless to interpret the king’s dream (Daniel 2:27). God specifies astrologers as among those who will be burned as stubble in God’s judgment (Isaiah 47:13-14). Astrology as a form of divination is expressly forbidden in Scripture (Deuteronomy 18:10-14). God forbade the children of Israel to worship or serve the “host of heaven” (Deuteronomy 4:19). Several times in their history, however, Israel fell into that very sin (2 Kings 17:16 is one example). Their worship of the stars brought God’s judgment each time.
The stars should awaken wonder at God’s power, wisdom, and infinitude. We should use the stars to keep track of time and place and to remind us of God’s faithful, covenant-keeping nature. All the while, we acknowledge the Creator of the heavens. Our wisdom comes from God, not the stars (James 1:5). The Word of God, the Bible, is our guide through life (Psalm 119:105).
