“Astrology” is “the ancient art or science of divining the fate and future of human beings from indications given by the positions of the stars and other heavenly bodies” – It assumes that our lives are largely influenced by the position and movement of heavenly bodies.
“Horoscope” is a chart of the position of the heavenly bodies, used to predict their influence on people’s lives.
“Zodiac” is a narrow strip or belt of the heavens in which the sun, moon, and principle planets appear as the earth revolves around the sun. This zone is divided into twelve sections, each of which contains a constellation (group of stars) for which that section has been named. Each of these 12 constellations is called a “sign of the Zodiac.” Whatever section the sun could be found in at the time of year when a person is born, that section is said to be the sign under which that person was born.
“Occult” is defined as: “magic, astrology, and other alleged sciences claiming use or knowledge of secret, mysterious, or supernatural agencies” – Random House College Dictionary. Other occult practices include witchcraft and sorcery, Satanism, spiritualism, fortune-telling, and psychics.
By definition, astrology is part of the occult. It is associated with hosts of other practices that are specifically condemned in Scripture. This should leads us at least question astrology.
The History of Astrology
Ancient people realized that the sun was essential to man’s needs, so they concluded that other heavenly bodies must be too. They thought that the largest heavenly bodies must be the most important, so they named the sun, moon, and largest planets after their main gods and the stars after lesser deities.
The movements of heavenly bodies were thought to represent activities of the gods. By studying these movements, men hoped to determine the will of the gods and so predict the future. If the heavenly bodies moved a certain way and certain events followed, then the next time they moved that way, similar things should happen.
Some 2000 years ago the Greeks studied the heavenly bodies mathematically and “scientifically” and defined the signs of the Zodiac. The names of Greek and Roman gods were then assigned to the planets.
So historically astrology is rooted in pagan idolatry. The basic concept of astrology – that the movements of heavenly bodies control our lives – is heathen idolatry from the foundation up.
