Everything in this Universe contains a “spiritual element” as everything in the Universe is God’s creation.
The martial arts that my (Protestant) nieces participate in are nothing more than a discipline of control and flexibility. All the bowing etc. that goes on is a sign of respect to the opponent, and is no more of a “spiritual element” than boxers touching gloves before a match.
Acupuncture works on the nerve lines of the body. My Protestant aunt recently had acupuncture for back problems and she said it helped immensely. I myself am looking into it for my arthritis, if my new insurance will help pay for some of it.
In other words, the pastor sounds like he’s from the school of “I don’t understand it, therefore it’s evil.”
