First of all, I want to say that I don't have a problem with EVERYTHING "New Agey". I think the techniques using meridians and chakras to reduce stress are actually helpful and you might catch me "tapping it out" after a particularly stressful day in the future. Even the energy and auras and all that I don't find particularly problematic from an orthodoxy standpoint. But the theology usually attached to these techniques is certainly heretical.
I caught three distinct heresies in what we were learning on Friday: deconstructionism, pantheism, and the all-sufficiency of the self.
Interspersed with practicing various stress reduction techniques (such as reiki, cranio-sacral, and "energy medicine"), was singing New Age "hymns", viewing videos, and reading excerpts of books on these subjects. During these times, she (or the authors or songwriters) would equivocate on "God," "the universe," and "Being". Several times she insisted that we are discovering that "everything is one." One "hymn's" lyrics read: "we are the heart... of the Spirit." At the end of the retreat, she read from a book by a woman who, at the end of her life, after suffering from a painful terminal illness, rejected "belief" and embraced not any "ultimate truth" but "her truth," for this is what sustained her in the end. The speaker shut the book and then proceeded to heap praises on the author for her bravery, beauty, and other such virtues, as if at the end of her life, she had attained enlightenment. The video we watched spoke in vague terms of a "revolution in consciousness" whereby humans everywhere are beginning to realize they have what it takes to make the world a better place. All this while images of cultural diversity play on the screen.
The problem with all this isn't the sentiment it expresses, for there's nothing wrong with making the world a better place, awakening your latent potential, or human solidarity. Rather, it's what is being taught. Christ is all-sufficient, not us. I am not one with the Holy Spirit, or my fellow man, or the earth, because I am sinful and God created us as distinct individuals. Sure I may share human nature and being created in the image of God with my fellow man, but ultimately I am an individual soul, specially created by the Heavenly Father. And no matter how comfortable "a truth" or "our truth" makes us, even on our deathbed, it's irrelevant to it's really being TRUE. Truth is objective and not in any way dependent on us.
It's for these reasons that on my evaluation at the end of the retreat I labeled the content not only un-Catholic, but un-Christian. The philosophy of Deepak Chopra and Eckhart Tolle (whose books were out on a display table the speaker had set up) is heresy. It contradicts the Christian worldview which we must take as a whole, not in just the bits we like.
Oh, and on top of all of this, the speaker was a nun.
