I agree with you. Did you happen to notice that in Section 8.1.: "Documents of the Catholic Church's Magisterium" no document sourced is dated earlier than 1989?
The more I think about this, the more disturbed I am by it. Given the current situation in the Church, the neglect and dismantling of our mystical and deep spiritual traditions in favor of bland and insipid substitutes, why IS the Vatican surprised at the attraction to the New Age movement? What are they doing to stem the tide? Do they even understand it? I'm afraid they have lost moral authority with the scandals and any document along these lines will simply be laughed off. What I am more afraid of is they are unaware of our Spiritual Traditions which could bring in the lost and spiritually searching.
