A fascinating article on the latest trends on religious beliefs and practices of Americans can be found here at the Pew Forum. It's worth a look and a ponder. From the article:
Though the U.S. is an overwhelmingly Christian country, significant minorities profess belief in a variety of Eastern or New Age beliefs. For instance, 24% of the public overall and 22% of Christians say they believe in reincarnation -- that people will be reborn in this world again and again. And similar numbers (25% of the public overall, 23% of Christians) believe in astrology. Nearly three-in-ten Americans say they have felt in touch with someone who has already died, almost one-in-five say they have seen or been in the presence of ghosts, and 15% have consulted a fortuneteller or a psychic.
This study reveals some incredible evidence of the decline of Christian beliefs especially among Christians themselves.
