What is the Bible and Christian view on Astrology? Being on this site has given me an opportunity to reflect and investigate more my beliefs and gain a greater understanding of the beliefs of other Christians. I was raised being taught that astrology was a pagan practice that went against Christian beliefs. Is that a view that is widely held by other Christians? 

I've heard counter views that astrology is another way in which God speaks to man, while others say there is no validity to it at all, and it is just a harmless form of amusement.

Is there a Biblical point of view on astrology?
Yes, the Bible speaks strongly against the pagan practice of Astrology, which was recognized as divination and associated with magic and sorcery.  Divination is defined as "the practice of attempting to foretell future events or discover hidden knowledge by occult or supernatural means", which would certainly include Astrology.

A number of scriptures associate astrology with pagan magic arts:


Isaiah 47:13: Let your astrologers come forward, those stargazers who make predictions month by month
Daniel 2:2: So the king summoned the magicians, enchanters, sorcerers and astrologers to tell him what he had dreamed.
Daniel 2:10: The astrologers answered the king, “There is no one on earth who can do what the king asks! No king, however great and mighty, has ever asked such a thing of any magician or enchanter or astrologer.


Leviticus 19:26 forbids divination:


  Do not practice divination or seek omens. 


as does and Deuteronomy 18:14


  The nations you will dispossess listen to those who practice sorcery or divination. But as for you, the LORD your God has not permitted you to do so


and numerous other scriptures:


Genesis 44:5: Isn’t this the cup my master drinks from and also uses for divination? This is a wicked thing you have done.
Deuteronomy 18:10: Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft,
Joshua 13:22: In addition to those slain in battle, the Israelites had put to the sword Balaam son of Beor, who practiced divination.
1 Samuel 15:23: For rebellion is like the sin of divination, and arrogance like the evil of idolatry. Because you have rejected the word of the LORD, he has rejected you as king.”
2 Kings 17:17: They sacrificed their sons and daughters in the fire. They practiced divination and sought omens and sold themselves to do evil in the eyes of the LORD, arousing his anger.
2 Kings 21:6: He sacrificed his own son in the fire, practiced divination, sought omens, and consulted mediums and spiritists. He did much evil in the eyes of the LORD, arousing his anger.
2 Chronicles 33:6: He sacrificed his children in the fire in the Valley of Ben Hinnom, practiced divination and witchcraft, sought omens, and consulted mediums and spiritists. He did much evil in the eyes of the LORD, arousing his anger.
Isaiah 2:6: They are full of superstitions from the East; they practice divination like the Philistines and embrace pagan customs.
Jeremiah 14:14: Then the LORD said to me, “The prophets are prophesying lies in my name. I have not sent them or appointed them or spoken to them. They are prophesying to you false visions, divinations, idolatries and the delusions of their own minds.
Ezekiel 12:24: For there will be no more false visions or flattering divinations among the people of Israel.
Ezekiel 13:6: Their visions are false and their divinations a lie. Even though the LORD has not sent them, they say, “The LORD declares,” and expect him to fulfill their words.


So if you accept that Astrology is a subset of divination, it seems clearly abhorrent to God.  Given the ensnaring nature of the occult, I would be engaging the "flee from all appearance" tactic with Astrology.
