I have studied many faiths including that of fundamentalists for many years.
The passages of Deuteronomy are often discussed in my work. I have been a minister for over 22 years and have very vast knowledge of the Bible. I have studied the customs and idioms of the Middle East, which by the way, without this knowledge, it is impossible to understand the Bible. I encourage you to learn the Bible with Biblical Scholars who have dedicated their entire lives to finding truth (unlike many among the extremely, ignorant fundamentalist ministers, who preach the so-called word of God).
Your own main library or State University may have the information you need. I recommend looking for works by Dr. George Lamsa who was one of the very few people to still speak the original language that Jesus spoke and helped translate the Bible in the 1930's. He received world renowned recognition for his works and President Eisenhower honored him during his time in office. Also, Dr. Rocco Errico has wonderful cassette tapes on this subject. Dr. Rocco Errico is a former student of Dr. Lamsa and was a Catholic priest who later became a fundamentalist minister (I believe in the Baptist faith) and then later with his studies on the Bible moved away totally from fundamentalism.
From what I have studied, this is what I have learned about the Deuteronomy attack:
Remember, not everyone claiming to be psychic actually is nor is everyone psychic also "spiritual". Every human being has within them the potential to develop psychic gifts. There are those who have information and use it wisely and those who choose to use it unwisely. Information is not knowledge. Knowledge is applied information. Wisdom is the result of living the knowledge and proving it works in your life. Anyone can claim to be psychic but few are truly dedicated enough to develop their spiritual self. If all you are is psychic and do not know your spiritual self, you can do little good for people or for yourself.
Deuteronomy passages still speak true today. Just look at all those ridiculous "psychic hot lines" and the gypsy fortunetellers who have been telling people they have spells on them and that for so many thousands of dollars they have the power to take them off! These are the kind of people Deuteronomy warned us about..
Unfortunately, the priests in the temples in the days and years to follow the death of Christ took all the power away from the people (claiming they were the only ones who had the power to heal and speak in tongues, etc.) and made the people afraid to have these gifts because they were now told if they possessed them in any form it had to be of the devil for only God gave them (the priests) these gifts. Because the priests of those days took away the power from the people and claimed they were the only ones authorized to have gifts, many people went back to finding answers for their own lives outside of themselves. Everything we have ever wanted or needed to know is right inside us, but many of us have no clue of the power within so the God-given power to be directed, guided, encouraged, loved and inspired and to know this exists within us is merely an idea for many. We seek out others who have gifts because we cannot find it inside ourselves. Yet, it's always been there.
The truth is Jesus said to masses of people (not just his disciples) (but everyone in the crowd that gathered as given in John 14:12) "Verily, Verily, I say unto you. He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father." The New Testament is filled with this kind of information.
You will want to order Patricia Mischell's upcoming book What Happens When We Die to receive more detailed information.
I will close with these words "Let this Mind be in you which was also in Christ." God bless you on your own very special path in life."
