"Thus says the Lord: Do not learn the way of the nations, and have no fear of the signs of the heavens, even though the nations fear them."
CCC 2116, Divination and Horoscopes
The Catechism doesn't mince words: "All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to 'unveil' the future" (CCC 2116). This includes horoscopes. The desire to know what's coming is deeply human, but God already told you the ending: He wins, and He wants you with Him. That's a better forecast than Mercury retrograde.
