Astrology teaches that the position of the planets and stars at the instant a person is born determines personality and even spiritual disposition. It teaches that everything that happens in a person’s life is caused by the position of the planets and stars and that God is not in control of what happens on earth — it is predestined by the position of the planets and stars.
The Bible condemns astrology in no uncertain terms:
Stand now with your enchantments and the multitude of your sorceries, in which you have labored from your youth; perhaps you will be able to profit, perhaps you will prevail. You are wearied in the multitude of your counsels; let now the astrologers, the stargazers, and the monthly prognosticators stand up and save you from what shall come upon you. Behold, they shall be as stubble; the fire shall burn them; they shall not deliver themselves from the power of the flame. (Isaiah 47:12-14)
”The good Christian should be aware of astrologers, and all those who make empty prophecies. The danger already exists that the astrologers have made a covenant with the devil to darken the spirit and to confine man in the bonds of hell.” – Augustine of Hippo
“Esau and Jacob were born of the same father and mother, at the same time, and under the same planets, but their nature was wholly different. You would persuade me that astrology is a true science?” – Martin Luther
