Christian views on astrology are different depending on what type of Christian you are. Generally, Christian religions believe that there is only one true God and that God is all-powerful and should be the one being to put your faith in. So, many Christians don't believe in astrology because it means believing in something other than God and putting your faith in something else. Some Christians might believe that astrology is okay as long as it doesn't interfere with worshiping God and putting faith in God above all else.
