Trinity

[삼위일체 · 三位一體 · Samwi Ilche · також: True Trinity, God-centered Trinity, Four-Position Trinity]

What Is the Trinity?

In Unification theology, the Trinity (삼위일체, Samwi Ilche, 三位一體) is not primarily a metaphysical mystery about three co-eternal divine Persons, as Nicene Christianity teaches. It is a relational, providential, and soteriological reality grounded in the Principle of Creation: the unity of God, a perfected man, and a perfected woman, brought together in true love through give-and-take action (수수작용, susu jakgyong, 授受作用), with God as the eternal center.

The Four-Position Foundation (사위기대, sawi gidae, 四位基臺) — God, husband, wife, and child — is the visible structure of the completed Trinity. Its formation fulfills the original purpose of creation, restores the lineage of heaven, and establishes the Kingdom of God on earth.

Originally, God's purpose for creating Adam and Eve was to form a trinity by raising them to be the True Parents of humankind united in harmonious oneness as husband and wife centered on God in a four-position foundation.

— The Trinity, Sun Myung Moon · Hyo Won Eu (03/19/1966)

This passage from the Exposition of the Divine Principle (원리강론, Wonni Gangron) makes clear that the Trinity is not a statement about God's internal structure in eternity but about God's creative purpose in history — a purpose that was blocked by the Fall and that Providence labors to restore.

Section I — Etymology and Korean Terminology

The Korean term 삼위일체 (Samwi Ilche, 三位一體) is the standard East Asian rendering of the Latin Trinitas, used throughout Korean Christian theology. It is composed of four characters: 三 (sam, “three”), 位 (wi, “position” or “rank”), 一 (il, “one”), and 體 (che, “body” or “substance”). The literal meaning is “three positions, one body.”

In mainstream Korean Christianity, samwi ilche carries the full Nicene meaning — Father, Son, and Holy Spirit as three coequal, co-eternal divine Persons of one substance. In Unification theology, the term is retained, but its referent is fundamentally reconceived.

The “three positions” are not three modes of the divine being but three participants in a love-centered relational structure: God (the incorporeal, vertical parent), the perfected man, and the perfected woman. The “one body” is not a metaphysical substance (ousia/hypostasis) but the unity of shimjeong (心情, heart) achieved through true love centering on God.

Instructive here is Rev. Moon's analysis of the Chinese character for heaven itself. In a 1972 sermon preserved in the Cheon Seong Gyeong (천성경, CSG), he explains that the character 天 (cheon, heaven) is composed of 二 (two) and 人 (person): “Two people. But what kind of people are they? They are people in whom heaven and earth can become completely one, both vertically and horizontally, by virtue of their perfect love. The fundamental basis for realizing the harmony of heaven and earth is love.” (CSG, 59-182, 07/16/1972.) This analysis reveals a consistent cosmological principle: unity (il) is always the fruit of genuine love between two who are distinct, not the collapse of distinction into uniformity.

The term 참된 삼위일체 (chamden samwi ilche, “True Trinity”) — the Trinity genuinely centered on God — appears in Rev. Moon's sermons in contrast to the 타락한 삼위일체 (tarakhan samwi ilche, “fallen trinity”) formed with Satan at its center, the tragic result of Adam and Eve's Fall.

Section II — Theological Definition: The Divine Principle and the Four-Position Foundation

The Exposition of the Divine Principle grounds the doctrine of the Trinity in the mechanics of creation itself, described in the Principle of Creation (창조원리, changjo wonni) through three interlocking concepts: the Universal Prime Force (만유원력, manyuwolyeok, 萬有原力), Give-and-Take Action (수수작용, 授受作用), and Origin-Division-Union Action (정분합작용, jeongbunhap jakgyong, 正分合作用).

God contains within Himself eternally existing dual characteristics (이성성상, iseongseongsang, 二性性相) — the masculine and the feminine, the internal nature and the external form. Through the Universal Prime Force, these dual characteristics engage in eternal give-and-take within God, sustaining His existence. When God creates, these dual characteristics are externalized (분립, bullip, “division”) into the substantial forms of man and woman. When a man and woman unite in true love centered on God, they return to oneness with God (합성일체화, hapseong ilchehwa, “synthesis into one body”) — forming the Four-Position Foundation. This completed structure is what the Exposition calls the Trinity.

The Wonni Gangron (원리강론) text at 8books.net/ko/dp describes this process systematically:

만유원력(萬有原力)으로 인하여 하나님 자체 내의 이성성상(二性性相)이 상대기준을 조성하여 수수작용을 하게 되면, 그 수수작용의 힘은 번식작용을 일으키어 하나님을 중심하고 이성성상의 실체대상으로 분립된다. 이와 같이 분립된 주체와 대상이 다시 만유원력에 의하여 상대기준을 조성함으로써 수수작용을 하면, 이것들은 다시 합성일체화(合性一體化)하여 하나님의 또 하나의 대상이 된다.

Through the Universal Prime Force, God's dual characteristics form a correlative base and engage in give-and-take action, which causes division into substantial subject and object. When these divided subject and object again form a correlative base and engage in give-and-take action, they synthesize into oneness, becoming another object to God. This synthesis — God–man–woman–child united in love — is the Trinity.

Four forms of the Trinity are distinguishable in the Exposition:

The Original (Intended) Trinity — God, perfected Adam, and perfected Eve, united in true love as the first True Parents. This was God's creative intention before the Fall.

The Fallen Trinity — when Adam and Eve fell, they formed a four-position foundation centered on Satan rather than God. Their descendants have continued to form trinities with Satan. This is why human civilization, despite its creativity, has been built on false love, broken lineage, and conflict.

The Spiritual Trinity — the resurrected Jesus and the Holy Spirit, in oneness with God, formed a spiritual trinity after the crucifixion. Because Jesus could not complete his physical mission and marry, this trinity could give only spiritual rebirth, not physical rebirth. Christianity gives spiritual salvation, but cannot remove original sin or restore the physical lineage.

The Complete (Restored) Trinity — the Trinity formed when the Lord of the Second Advent comes in the flesh, finds his Bride, and together they become True Parents both spiritually and physically. This completes the mission of the first Adam and of Jesus, removes original sin, and enables every blessed family on earth to form its own God-centered trinity.

Christ must return in the flesh and find his Bride. They will form on the earth a perfect trinity with God and become True Parents both spiritually and physically. They will give fallen people rebirth both spiritually and physically, removing their original sin and enabling them to build trinities on earth with God as the center.

— The Trinity, Sun Myung Moon · Hyo Won Eu (03/19/1966)

The Completed Testament Age is defined precisely by this: the physical Trinity — God, True Father, and True Mother — has been established on earth, and humanity is now invited, family by family, to be engrafted into it.

Section III — God as Vertical Father, Adam as Horizontal Parent

One of the most significant Unification contributions to Trinitarian thought is the distinction between the vertical parent (하늘부모, haneulbomo) and the horizontal parent (땅의 부모, ttangui bomo). This distinction, developed extensively in the Cheon Seong Gyeong (Book 1, Chapter 2), provides the metaphysical grammar for understanding why the Trinity must include a physical couple and not remain purely divine.

The Cheon Seong Gyeong teaches that God created Adam and Eve not merely as objects of love but as His bodily representatives on earth — the visible form of the invisible God:

God created human beings to place them in the equivalent parents' position, and also to acquire a body. The equivalent parents' position means internal and external; in other words, the external God is Adam and Eve, and God Himself is the internal God. In relation to the body, God is Adam and Eve, and in relation to the mind, God is the invisible God. (CSG, 133-91, 07/10/1984)

This teaching means that the Trinity is not completed until God's invisible nature is given a visible body — until the incorporeal God finds His external form in a perfected husband and wife. God is the vertical axis; Adam and Eve are the horizontal plane. When the vertical and horizontal meet at a perfect 90-degree angle, the four-position foundation is established and the Kingdom of Heaven begins.

The Creator is the vertical Father who is centered on vertical true love. Had they not fallen, the original human ancestors, Adam and Eve, would have been the perfected horizontal and physical parents, standing in the position where they could become fully one with God at a 90-degree angle.

— Cheon Seong Gyeong, Sun Myung Moon (210-139, 12/17/1990)

The 90-degree axis — vertical God united with horizontal parents — is the geometric image of the completed Trinity. This is not poetic language but structural theology: the family is the point where vertical love (from God above) and horizontal love (between husband and wife) intersect and become one reality.

Section IV — Providential Context: Three Ages, Three Trinities

Unification theology reads providential history through three dispensational ages — the Old Testament Age (구약시대), the New Testament Age (신약시대), and the Completed Testament Age (성약시대) — each corresponding to a stage of restoration and to a form of the Trinity.

In the Old Testament Age, God worked through indemnity conditions, sacrificial offerings, and the nation of Israel to prepare the foundation for the Messiah. The Trinity was not yet visible: God worked from behind history, the perfected Adam had not come, and humanity lived in the age of the servant (종의 시대, jongui sidae). The relationship between God and His people was mediated through law and prophets, not direct parental shimjeong.

In the New Testament Age, Jesus came as the Second Adam. Had he found his Bride and established a God-centered family, the physical Trinity would have been formed in his generation. But Jesus was crucified before that could happen. His resurrection, together with the Holy Spirit, formed only the spiritual Trinity — what the Exposition calls the “spiritual True Parents.” Christians receive spiritual rebirth as spiritual children of Jesus and the Holy Spirit, but physical rebirth and the removal of original sin await the Completed Testament Age.

In the Completed Testament Age, the Lord of the Second Advent comes as the Third Adam. Peace Message I (하나님의 이상가정과 평화이상세계왕국 I, 2005), delivered by Rev. Moon at Lincoln Center in New York, articulates the urgency and the vision:

하나님께서 인간을 창조한 궁극적 목적이 어디에 있다고 생각하십니까? 참사랑을 중심한 이상가정의 완성을 통해 기쁨을 느끼는 것이었습니다.

“What do you think is the ultimate purpose for which God created human beings? It was to feel joy through the completion of the ideal family centered on true love.” The completion of the ideal family — God, True Father, True Mother, and their blessed children — is the realization of the Trinity in history.

We must create this structure of trinities. I have formed trinities, centering on you, to fulfill this. In forming the trinities, ten of you must become united, centering on three trinities. The reason is that the trinity represents the three disciples who prayed with the Lord in the Garden of Gethsemane.

— Sun Myung Moon (01/03/1958) The Meaning of the Trinity

This 1958 sermon shows that from the earliest years of the Unification movement, the Trinity was understood not merely as a doctrinal formula but as a concrete organizational and spiritual practice — the formation of trinities of families who become “one in heart” and through their unity restore the failures of history.

Section V — The Family as the Core of the Trinity: Teachings from Cham Gajong

The book 천국을 여는 문 참가정 (The True Family — Gateway to Heaven) gathers Rev. Moon's teachings specifically on the family as the center of the cosmos.

Chapter 1 — "The Family is the Central Model of Heaven” — provides some of the deepest elaborations of the Trinity as it applies to family life.

The text from sermon 30-80 (03/17/1970) identifies the family as the structure in which all three ages of love — past, present, and future — converge:

부모와 하나되는 것은 역사와 현실이 만나는 것입니다. 여기서 '나'는 부모를 사랑하므로 과거를 사랑할 수 있고, 상대를 사랑하므로 현실을 사랑할 수 있고, 자녀를 사랑하므로 미래를 사랑할 수 있습니다. 그러므로 나는 3시대의 사랑을 체험할 수 있는 것입니다.

“Becoming one with parents means that history and reality meet. Here, 'I' can love the past by loving my parents, love the present by loving my partner, and love the future by loving my children. Therefore, I can experience the love of three ages.”

This passage is a masterful theological observation: the family is the structure in which time itself is unified. The Trinity — three positions, one body — is lived as three generations of love meeting in a single household. The grandfather and grandmother (past), the husband and wife (present), and the children (future) together constitute the temporal form of the Trinity, the family of God extended through time.

The same passage continues: “세가지 사랑이 결집된 핵심체가 바로 가정입니다” — “The family is the core structure in which three kinds of love are concentrated.” This is precisely the definition of the Trinity reconceived from the perspective of shimjeong theology: not three abstract divine Persons but three living loves — parental love, conjugal love, and children's love — united in the family by the love of God at the center.

God will come and dwell in Adam and Eve only when they love each other as God loves. He cannot come if they just do as they please. The invisible God will come to them only when they become completely one.

— Cheon Seong Gyeong, Sun Myung Moon (112-103, 04/05/1981)

The Trinity is thus not a static eternal structure but a dynamic event — the moment when God descends into the love of a perfected couple. The husband and wife's union, when it reaches the quality of God's own love, becomes the meeting point of heaven and earth, the place where the invisible God acquires a visible body and the Kingdom of Heaven becomes a lived reality.

Section VI — Comparative Perspective

Classical Christianity defines the Trinity as one God in three coequal, co-eternal, consubstantial Persons — Father, Son, and Holy Spirit — a doctrine crystallized at the Councils of Nicaea (325) and Constantinople (381) and codified in the Nicene Creed. Young Oon Kim's analysis of The Doctrine of the Trinity provides the most thorough Unificationist engagement with this history. She argues that the word trias (Trinity) does not appear in the New Testament and was first used by Theophilus of Antioch around 180 AD. The developed trinitarian formula represents an amalgam of Judeo-Christian faith and Hellenistic philosophy, and has historically fragmented the Church into Athanasian and Arian factions, Nestorians and Monophysites, Chalcedonian and non-Chalcedonian branches.

The Unification critique of classical Trinitarianism targets three specific claims. First, the claim that Jesus is ontologically identical in substance with God (homoousios) is rejected: Jesus achieved perfect moral and spiritual oneness with God through obedience, but this is a relational union, not metaphysical identity. Second, the Holy Spirit is understood not as the third coequal Person of the Godhead but as the feminine aspect of God's parental love, working in history as the spiritual mother — a function fully embodied in True Mother at the Second Advent. Third, classical Trinitarianism is criticized for being absorbed in God's inner eternal nature while neglecting God's outward relational purpose: the creation of the family of God.

The 1981 essay by Young Oon Kim articulates the Unification alternative: “Because the Divine Principle is especially concerned with the restoration of divine sovereignty over creation, we stress the trinitarian way by which the kingdom of heaven will be established upon the earth. If there had been no Fall, Adam and Eve would have realized the purpose of creation by founding a God-centered family.”

Judaism affirms strict divine unity and would find both the classical Trinity and the Unification Trinity requiring careful distinction. Judaism's concern with any “partnership” or plurality in the divine (שִׁתּוּף, shittuf) is addressed differently by the two theologies: classical Christianity asserts three divine Persons, which Jewish thought historically rejects; Unification theology asserts one God whose creative purpose is fulfilled through a perfected human couple — a position closer to the Jewish emphasis on the sanctity of marriage as a divine commandment and on the family as the vehicle of God's covenant with Israel.

Islam affirms absolute divine unity (توحيد, tawhid) and explicitly condemns association of any being with God (شِرْك, shirk). The Quranic critique (Surah 4:171, 5:73) targets the classical three-Persons formula. The Unification Trinity, by defining the Trinity as a relational achievement rather than three divine Persons, sidesteps this critique: there is only one God, and the “Trinity” names the structure through which God's love is fully realized in creation — not a claim of divine plurality.

Buddhism,, particularly in its Mahayana traditions, contains the concept of the Trikāya (三身, “three bodies of the Buddha”): the Dharmakāya (법신, truth body), the Saṃbhogakāya (보신, enjoyment body), and the Nirmāṇakāya (화신, transformation body). From a Unification perspective, this threefold structure reflects the universal principle of the Original Being (정분합, jeongbunhap): God as the absolute source, God as expressed in substantial form, and God as active in the world through particular agents of restoration. The convergence across traditions points to a deep structure of reality that the Divine Principle names as the Four-Position Foundation.

Section VII — Trinity Groups as a Providential Practice

One of the most distinctive and historically important applications of Unification Trinity theology was the formation of trinity groups (삼위일체 그룹) — units of three families or three individuals who are spiritually united in heart, prayer, and mission.

This practice is directly grounded in Rev. Moon's 1958 sermon The Meaning of the Trinity, which traces the structure to Jesus' use of Peter, James, and John as his inner circle — and to their failure in Gethsemane, when they fell asleep instead of praying with him at the hour of his greatest need.

The three people who belong to the trinity must become one in heart. If not, you cannot enter Heaven. The idea of unification begins from this point. If three people cannot become one in heart, they cannot enter Heaven.

— Sun Myung Moon (01/03/1958) The Meaning of the Trinity

Three trinity groups of three form nine families plus a leader — ten units — which horizontally represents the ten generations from Adam to Noah. Three groups of ten form thirty-six couples, the number Rev. Moon blessed first in 1961, and which represent the restoration of the twelve sons of Jacob, the twelve tribes of Moses, and the twelve apostles of Jesus, the central figures of 6,000 years of providential history combined in one ceremony.

This numerical theology of the Trinity — three, twelve, thirty-six, seventy-two — is not arithmetical mysticism but a systematic effort to enact the providential restoration of every failed dispensational structure, family by family and generation by generation.

Section VIII — Academic Note

In New Religious Movements scholarship, the Unification doctrine of the Trinity has received limited systematic attention compared to the movement's social practices. Young Oon Kim's essays, available at tplegacy.net, remain the most theologically rigorous treatments, engaging patristic sources, Cappadocian theology, and modern systematic theologians, including Karl Barth, John Macquarrie, and H. E. W. Turner.

The most significant academic issue is the relationship between the Unification Trinity and social trinitarianism — the theological tradition, associated with the Cappadocian Fathers (Basil, Gregory of Nyssa, Gregory Nazianzen) and revived in the 20th century by Jürgen Moltmann (The Trinity and the Kingdom, 1980) and Leonardo Boff, that understands the inner life of God as a community of mutual love and uses this as a model for human social life. The structural resonances with Unification theology are considerable: both views see the Trinity as inherently relational rather than ontological, and both draw a direct line from Trinitarian love to the ethics of community and family.

The critical difference is that Unification theology places the human couple within the Trinitarian structure — not merely modeled after it — by identifying the perfected husband and wife as the bodily expression of God's own dual characteristics. This is not a structural parallel but an ontological claim: the family is the Trinity made visible. No classical Christian theology, including social trinitarianism, makes this claim.

From the perspective of New Religious Movements sociology, the Unification trinity groups constitute a distinctive form of intentional community organization — smaller and more intimate than a congregation, larger and more accountable than an individual family. Their study offers potential insight into the sociology of cell-group structures across religious traditions, including evangelical Protestant “accountability triads,” Quaker clearness committees, and the traditional Jewish chevrutah (paired study partner), all of which reflect the intuition that three-person or small-group bonds carry a particular spiritual resilience unavailable in solitary or dyadic relationships.
