Any Christian has to respect astrology to the extent that it can reveal things about the universe. After all, the 3 wise men saw the star of David, knew the sign that it meant a new king of Israel.

That said, "modern" astrology is filled with gobboldy gook and nonsense, with vaguely worded predictions that could mean anything, that are meant to reveal hidden knowledge but instead lead people astray.

Bottom line, astrology is only useful for reading "signs", again, like "there's Orion, winter is on the way."
