Getting off the subject of the Disney Channel (which I doubt is harmful to someone who is a well formed Christian) , I would say the New Age beliefs or religion or mindset is satanic but not in that it directly promotes the worship of Satan. In fact, the people I know whom I would call ‘new age’, or who identify themselves as such, usually don’t even believe in Satan. And that’s an indication of the real problem with ‘new age’.
The New Age doesn’t need the God and Father of Our Lord Jesus Christ. They don’t need a savior. Everything’s really okay if we just get in touch with ourselves, our higher selves, the power of the universe, and think positive thoughts. Most or all of the spirits or spiritual influences out there are good (they believe). It’s all a matter of becoming ‘enlightened’ and in tune with the universe and our inner selves. We are all basically good and have undreamed of powers within us. All ways lead to God; all rivers end in the sea; in the end we all will become enlightened.
The book Jonathan Livingston Seagull, now some 50 years old, and extremely popular then and now, is an example. The power to fly is within us, we just have to discover, use, and control it.
The ideas of conversion, surrender to God’s will, service to God and our neighbor, gaining our life by losing it, obedience to authority, taking up the cross daily, etc. are not part of the New Age beliefs. So yeah, I think it’s satanic.
