Some religious organizations (Seventh-day Adventists, Seventh-Day Baptists, and certain others) claim that Christians must not worship on Sunday but on Saturday, the Jewish Sabbath. They claim that, at some unnamed time after the apostolic age, the Church "changed" the day of worship from Saturday to Sunday.
Members of what is commonly called the "New Age" movement often claim that early Christians believed in reincarnation. Shirley MacLaine, an avid New Age disciple, recalls being taught: "The theory of reincarnation is recorded in the Bible. But the proper interpretations were struck from it during an ecumenical council meeting of the Catholic Church in Constantinople sometime around A.D. 553, called the Council of Nicaea [sic]" (Out on a Limb, 234–35).
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).
