The Catechism of the Catholic Church (2116) says:
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.
There are two things astrologers claim to be able to determine through analysis of the stars: (1) an individual’s’ personality traits, and (2) universal influences on an individual’s history–past, present, and future.
The former, hereafter referred to as zodiac astrology, is done by consulting the positions of the stars at the time and location of a person’s birth. From this information, the astrologer observes the positions of each of the “planets,” including the Sun and Pluto, in one of twelve zones in the sky or zodiac signs, and makes an assessment about that individual’s personality based on that information. At this level, no claim is made to knowledge of the future.
The latter is done by cross-referencing the former data with the positions of the stars at a past, current or future timeframe. At this level, the astrologer claims to be able to know the influence the universe will have over a person’s life at any given time, most importantly the future. It is this level of astrology from which horoscopes are derived.
It is the latter level of astrology which the Catechism seems to condemn, and not what I refer to here as zodiac astrology. Am I wrong?
I submit the matter to the esteemed apologists at Catholic Answers.
