Those of you interested in engaging with the concept of Chi and the related disciplines of Traditional Chinese Medicine, Martial Arts, Fung Shui and so forth, would be well advised to read Christian Guideposts on Chi: An Evangelical Assessment of Chi and Related Activities by Brett Yardley. Here are a few comments I found worthy of consideration:

It is unfortunate that at this stage some Christians have attempted to dispense with the entire notion of ch’i as wholly incompatible with Christianity simply due to its eastern origins. Yet, this is an overly simplistic type of reasoning, since to belittle and reject all eastern thought solely by pointing out its source is a genetic fallacy. Christians will do well to remember that Judaism and Christianity, despite the unfortunate label of being “Western Religions,” were in fact born in the east amongst eastern people.

In general, Christians can relate to the overall summary of [Traditional Chinese Medicine’s] pragmatic methods of “all things in moderation.” In fact [Traditional Chinese Medicine’s] push to moderate one’s lifestyle, control sexual urges, and caring for one’s body (which Paul refers to as a temple of the Lord, 1 Corinthians 6:18), are in line with a Christian worldview. However, embracing the philosophical awareness and wisdom that [Traditional Chinese Medicine] is supposed to provide for personal wellness should be considered suspect since the Christian’s personal well-being and wisdom should come from their relationship with Christ.

So long as Christians still abstain from the divination practices of Feng Shui, taking this definition would free users to see Feng Shui as nothing more than an aesthetic art form

No, detachment is not enough; we must go on to attachment. The detachment from the confusion all around us is in order to have a richer attachment to God. Christian meditation leads us to inner wholeness necessary to give ourselves to God freely.

As a result, the “soft” side of martial arts dealing with inner development often includes harmony with and controlling ch’i, as opposed to the “hard” side including physical conditioning and strikes.

As previously mentioned, the use and definition of ch’i neither fits any of the gifts of the Holy Spirit, nor acts in way that would serve the ministries of the church.

According to the Japanese Catholic Theologian Yohji Inoue, the foundation of Western thinking is “substance” (object) while Japanese thinking is “the field which envelopes substances.”
