The Roman Catholic church certainly practices energy work every bit as much as we do, however it is only taught to priests. They seem to not trust this aspect to the general population. But during mass the priests smudge and use Frankinsense and Myrrh, they believe they are transforming the host into the body and blood of Jesus Christ. They believe in visions, demonic possession, etc. The sacraments are kind of like attunements in a way. The Charismatic movement of the church does hands on faith healing.
I'm raised in this faith, and I've had many conversations with my mother about the similarities between Roman Catholicism and the Reiki. I pointed out that St. Teresa had many visions and the Bible talks about visions and dreams, etc. All this psychic stuff is what concerns people, and yet the religion is ripe with the same stuff they fear.
Your website sounds like yet another person with too much time on their hands shooting from the hip. Unfortunately there are so many ignorant people who get such a high from negativity. They definitely can use some Reiki.
Namaste,
