Well a Christian may understand these two concepts. But what a Christian can't do is agree that the Energy of Chi or the balance of Ying-yang exists. By stating that only movements of T'ai Chi can be learned or studied by anyone that claims Christianity. I would deem a Christian T'ai chi practicer similar to Atheists that attend a Lutheran School.



These concepts clearly cannot be

Well once again understanding the concept may be attainable.
Just like someone who's a non-believer to the Big 3 may understand concepts within them, even tho they don't believe it to be true. Believing it to be true is the line of demarcation that separates Christian vs. Taoist. Solarus I'm pretty sure you understand that you can't be Christian and practice Tao at the same time. (Hence the post) But if you do the movements only religous aspect may be separated.


In capoeira,

If there's no way to separate it ...then it's a no can do.

Some i've heard were for exercise (Yoga). Most common Self-defense. We would probably agree that a Christian Practicer would not be as emmersed in these arts as someone who believes it with all of their heart.
