The Mingled Spirit

“But he who is joined to the Lord is one spirit.” — 1 Corinthians 6:17

“The Spirit Himself witnesses with our spirit that we are children of God.” — Romans 8:16

What Scripture Says

The expression “the mingled spirit” derives from an understanding of 1 Corinthians 6:17. In Greek, the word for “joined” is κολλάω (kollao), whose root means “to glue together.” In medical texts it described the uniting of wounds. Bengel commented: “One spirit — so closely, as husband and wife are one body.” (BibleHub — 1 Cor 6:17 Commentaries)

This is not two spirits simply existing side by side but organically united as “one spirit” (ἓν πνεῦμά). (BibleHub — 1 Cor 6:17 Greek Text)

Romans 8:16 uses συμμαρτυρέω (summartureo, “to witness together with”) to describe the relationship between the Holy Spirit and our spirit — syn (together, expressing intimacy) plus martureo (to witness). This is not an external directive but the intimate cooperation of two spirits operating as one. (StudyLight — Rom 8:16)

Romans 8:4 speaks of believers “walking according to the spirit.” The Recovery Version footnote explains that the “spirit” here refers to “our regenerated human spirit indwelt by and mingled with the Spirit.” Throughout Romans 8, many instances of “spirit” are difficult to assign definitively to God’s Holy Spirit or to our regenerated human spirit — “unless it is clearly designated.” This very ambiguity suggests the two spirits have been mingled into one. (Recovery Version Romans 8)

In 2 Timothy 4:22, Galatians 6:18, and Philemon 25, Paul’s benedictions say “The Lord be with your spirit” — not simply “with you” but specifically with the human spirit, indicating the Lord’s indwelling takes place in this precise location. (BibleHub — 2 Tim 4:22)

How the Church Has Understood It

The Church Fathers

Irenaeus (c. 130–202) used the Latin word commixtio (“commingling”) in Against Heresies Book V, Chapter 6: “The perfect man consists in the commingling and the union of the soul receiving the spirit of the Father.” “When the spirit here blended with the soul is united to God’s handiwork, the man is rendered spiritual and perfect.” (Irenaeus, Against Heresies V.6 (NewAdvent))

Irenaeus’s use of commixtio to describe the union of God’s Spirit with the human soul/spirit is the most direct patristic parallel to the “mingled spirit” teaching.

Maximus the Confessor (c. 580–662) taught that in Christ “divine and human energy are in cooperation, and not as a mixed form of both” — the divine interpenetrates our humanity and our humanity interpenetrates the divine, yet the two remain “in unconfused perichoretic union.” This Chalcedonian framework maintained that two natures remain distinct while fully interpenetrating. (Forging Ploughshares — Maximus the Confessor)

The Reformation

Calvin (1509–1564) placed union with Christ at the center of his soteriology. He called the Holy Spirit “the bond by which Christ effectually binds us to himself” (Institutes 3.1.1). He stressed that this “mystical union” is of “the highest degree of importance” (3.11.10). On 1 Corinthians 6:17, Calvin commented that believers become “not merely one flesh with Christ, but also one spirit.” He insisted this union is “not by the inflowing of substance, but by the grace and power of the Spirit” — neither mere moral imitation nor substantial ontological mixture, but a real spiritual union. (TGC — Union with Christ; BibleHub — Calvin’s Commentary on 1 Cor 6)

How the Local Church Teaches It

Brother Watchman Nee

Brother Watchman Nee taught in The Spiritual Man that man has three parts — spirit, soul, and body — with the spirit having three functions: conscience, intuition, and fellowship. He wrote: “God is known directly through the spirit. Man worships God and communicates with God directly through the spirit — that is, through the ‘inner man’ — and not through the soul or the outward man.” (Nee, The Spiritual Man, Ch. 3)

In The Breaking of the Outer Man and the Release of the Spirit, he stated more explicitly: “The release of the spirit is the release of the human spirit as well as that of the Holy Spirit, who is in the spirit of man. Since the Holy Spirit and our spirit are joined into one, they can be distinguished only in name, not in fact. Since the release of one means the release of both, others can touch the Holy Spirit whenever they touch our spirit.” (Nee, The Breaking of the Outer Man, Ch. 1)

Brother Witness Lee

Brother Witness Lee developed “the mingled spirit” into one of the most distinctive teachings in the Lord’s recovery. He called 1 Corinthians 6:17 “one of the greatest verses in the Bible.” (Ministry Samples — The Divine Spirit and the Human Spirit)

He used the analogy of tea and water: “He mingles with us in our spirit as tea mingles with water… After tea is put into water, it is difficult to separate the tea from the water. That is why I call it tea-water.” Unlike oil floating on water (which never mixes), the two spirits are organically united. (Lesson Book Level 3, Ch. 17)

He traced the mingled spirit through Ephesians — “a spirit of wisdom and revelation” (1:17), “built together into a dwelling place of God in spirit” (2:22), “renewed in the spirit of your mind” (4:23), “be filled in spirit” (5:18), “praying at every time in spirit” (6:18). He noted that the mingled spirit “is realized by faith” rather than by seeking emotional experience. (Ministry Samples — The Mingled Spirit in Ephesians)

On “not producing a third nature,” Brother Witness Lee explicitly addressed the Eutychian concern: “But in Him both the divine essence and the human essence remain and are distinguishable. These essences are mingled in Him as one person without the producing of a third nature.” His use of “mingle” follows the dictionary definition: “to bring or combine together or with something else so that the components remain distinguishable in the combination.” (lctestimony.org — A Defense of Seventeen Quotations)

Controversy and Clarification

The term “mingling” drew controversy. The 2007 open letter called on Living Stream Ministry to clarify certain of Brother Witness Lee’s formulations. Critics argued that “mingling” implied producing a third nature — the Eutychian heresy condemned at Chalcedon in 451. (Apologetics Index — Open Letter)

In 2006, Fuller Theological Seminary’s faculty (including President Richard Mouw) held five dialogues with local church representatives, discussing topics including “mingling.” Fuller’s conclusion: the local churches’ teaching is “unequivocally orthodox,” and they recommended extending “the right hand of fellowship.” (lctestimony.org — Dialogue with Fuller)

After a six-year primary research project, the Christian Research Institute published its conclusion in 2009. Hank Hanegraaff declared: “We were wrong!” Elliot Miller (editor-in-chief, 30+ years at CRI) wrote a seven-part series concluding the local churches are “not an ‘aberrant Christian group’ but a solid orthodox group of believers.” On the “mingling” terminology specifically, CRI researchers found that Lee’s use of “certain hot button words associated in our minds with heresy or cultism” had led to misunderstanding. A closer examination of context and terminology revealed that his views “do not really mean what critics claimed.” (CRI — We Were Wrong)

Comparison

	Historical Orthodox	Lord’s Recovery
Core verses	1 Cor. 6:17; Rom. 8:16	Same, plus Rom. 8:4, 2 Tim. 4:22, and every instance of “spirit” in Ephesians
Nature of the union	”Mystical union” — real spiritual union, not substantial mixture (Calvin)	“Mingling” — two spirits organically united as one spirit, with each essence remaining distinguishable
Terminology	”Union with Christ,” “the Spirit’s indwelling,” “mystical union"	"The mingled spirit,” “one spirit,” “tea-water,” “the consummation of the processed Triune God”
Patristic precedent	Irenaeus used commixtio (commingling) for the Spirit’s union with the soul	Cites Irenaeus as a patristic precedent
Practice	Union is the basis for justification and sanctification	The mingled spirit is the practical basis for daily Christian and church life — “walk according to the spirit” in everything
Where they align	The believer’s spirit and the Holy Spirit have a real, not merely symbolic, union (1 Cor. 6:17)
Where they diverge	Orthodoxy generally uses “union” and “indwelling,” avoiding “mingling” to prevent Eutychian associations; the recovery uses “mingling” and defends it with the dictionary definition and the Levitical meal offering (fine flour mingled with oil)

Back to the Text

Paul put it simply: “He who is joined to the Lord is one spirit.”

This is not an esoteric doctrine — it is a fact every believer can experience daily. When you turn to your spirit in prayer, when you worship in spirit, when you walk by the spirit rather than by the flesh — you are experiencing the mingled spirit.

The debate over terminology can continue. But the testimony of Scripture is clear: your spirit and God’s Spirit have been joined as one. This is not something you need to strive for — it is a gift you received when you were born again.

“The Lord be with your spirit.” — 2 Timothy 4:22
