CAN A CHRISTIAN PRACTICE MARTIAL ARTS?
You ask an important question: Can a Christian practice martial arts? My immediate answer is yes, with caution. There are many types of martial arts, and of course, some are wrapped up in Eastern mysticism and therefore should be shunned.
However, not all marital arts are religious in nature. There is nothing wrong with a Christian being a soldier, or being trained and prepared to defend themselves. In fact the Westminster Confession of Faith requires all lawful studies and endeavours to preserve life and property. (See Faith and Firearms article).
