"There is a radical difference between Reiki therapy and the healing by divine power in which Christians believe: for Christians the access to divine healing is by prayer to Christ as Lord and Savior, while the essence of Reiki is not a prayer but a technique," the bishops said in a statement.You can read what the Bishops have to say about Reiki here(pdf).
And then there's the fact that "neither the Scriptures nor the Christian tradition as a whole speak of the natural world as based on 'universal life energy' that is subject to manipulation by the natural human power of thought and will," the bishops said.
I wonder what Catholic Bishops have to say about the efficacy of prayer for curing the sick. Is it more or less effective than Reiki?
Maybe this all just an April Fool's joke.
