Horoscopes are a means of attempting to know the future through an astrologer’s interpretation of Sun sign astrology. The Catholic Church teaches against the use of horoscopes and other such fortune-telling practices such as astrology, palm reading, clairvoyance, ouija boards, and mediums because they attempt to take the place of God. Some of these things use evil as the source of their power, others are based on mathematical formulas, and still others are people simply looking to make a quick profit from willing seekers.
The Catechism of the Catholic Church states, “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. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.” CCC 2116
