Is Astrology Always Wrong?
Nope, just often misapplied
Stars were created to be signs (Genesis 1:14), but as with every message (including Scriptures) a flawed exegesis gives flawed conclusions.
It appears that a baby's earliest impressions have a strong influence on its character development. A child that is born under a winter-sky will initially experience lots of darkness, mothers with fluffy sweaters and the smell of hot chocolate. A child born under a summer-sky will experience lots of light, lots of naked limbs and the smell of vegetation.
Certainly there is a connection between character-tendency and star sign. Still, every message—including the Tree of Knowledge of Good and Evil, science and astrology—should lead to Christ. If you stumble upon the path of above mentioned heathen astrologers (the Matthew-magi) it comes highly recommended that you take it.
