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.”
Catechism of the Catholic Church, paragraph 2116
By consulting a horoscope to show ourselves the path for our day we usurp the place of God in whose hands we should place our concerns allowing him to lead us down the path of holiness in discerning his will for us. Astrology, fortune-telling, tarot cards, and the like are no replacement for God’s providence.
“God can reveal the future to his prophets or to other saints. Still, a sound Christian attitude consists in putting oneself confidently into the hands of Providence for whatever concerns the future, and giving up all unhealthy curiosity about it. Improvidence, however, can constitute a lack of responsibility.”
Catechism of the Catholic Church, paragraph 2115
What should I do if I have read a horoscope or visited a fortune-teller?
If you have been consulting your horoscope, visited a fortune-teller, involved in conjuring spirits, or used a ouija board you should go to confession as soon as you can. These acts may be mortal sins or they may be venial sins depending on the circumstances, but nonetheless they are considered sin and require repentance.
