Trinitarian Cosmology, as it surfaces across the depth-psychology corpus, designates the speculative project of reading the structure of the cosmos through the threefold dynamic of Father, Son, and Holy Spirit — a project that spans patristic theology, medieval alchemy, and modern analytical psychology. Jung stands as the corpus's most consequential interpreter, arguing that the Trinity is not merely a revealed dogma but an emergent symbol of psychic wholeness: 'trinitarian thinking' expresses a collective, unconscious need for a 'saving formula of wholeness' at moments of psychic transformation. Von Franz elaborates the cosmological dimension, tracing the unus mundus and its mathematical order — number assigned to the Son, measure to the Father, weight to the Spirit — as the Trinitarian template inscribed into the Godhead's pre-creational plan. The Philokalic and Damascene traditions supply the doctrinal substrate, mapping the three hypostases as coeternal and coessential while insisting that their unity is the principle through which all creation proceeds. Edinger psychologizes the triangular symbol as a dynamic that ruptures static uroboric wholeness into temporal, dialectical process. A persistent tension throughout is the relation between three and four: whether the Trinity is the adequate symbol of totality or whether a fourth — the feminine, the earthly, the shadow — must supplement it. Armstrong, Bulgakov, and Hillman add further vectors from comparative religion, sophiology, and archetypal psychology respectively.
Thinking in the magic circle of the Trinity, or trinitarian thinking, is in truth motivated by the 'Holy Spirit' in so far as it is never a question of mere cogitation but of giving expression to imponderable psychic events.
Jung argues that Trinitarian cosmology is not a rational construct but the spontaneous symbolic product of collective unconscious processes that surpass all personal motivation.

The Trinity is undoubtedly a higher form of God-concept than mere unity, since it corresponds to a level of reflection on which man has become more conscious.
Jung presents the Trinitarian God-concept as an evolutionary advance in human self-consciousness, situating it within a developmental account of the divine drama.
, Psychology and Religion: West and East, 1958thesis
Certain primal forms, ideas, prototypes constitute together the archetypus mundus or 'exemplar' of the universe in God's mind. It contains a mathematical order which is closely related to the Trinity: number belonging to the Son, measure to the Father and weight to the Holy Spirit.
Von Franz identifies the Trinitarian structure as the organizing principle of the pre-creational unus mundus, rendering Trinitarian cosmology into an archetypal theory of cosmic order.

God's omniscient direction of the world should lead us to observe measure, since he ordered all things in measure, number, and weight... in the power of the Father, to whom is attributed measure, in that of the Son, to whom appertains number, and in that of the Holy Spirit, to whom is ascribed weight.
Von Franz cites Albertus Magnus to show that Trinitarian cosmology distributes the three divine persons as structuring principles of cosmic measure, number, and weight.

An attitude emphasizing static completeness must be complemented by the trinitarian dynamic principle. The threefold temporal process breaks up the static, eternal state and subjects it to a development of events in time involving recurrent conflicts and resolutions according to the formula thesis, antithesis, synthesis.
Edinger reads the Trinitarian structure as a dynamic cosmological principle that introduces temporal process and dialectical movement into an otherwise static totality.

In the Father is eternity, in the Son equality, in the Holy Spirit the bond of eternity and equality; for as it is said, Like as the Father is, so is the Son, and so also is the Holy Spirit, and these three are One, [which the Philosopher would have to be] body, spirit, and soul, for all perfection consisteth in the number three.
The Aurora Consurgens passage equates the alchemical triad of body, spirit, and soul with the Trinitarian persons, embedding Trinitarian cosmology within the alchemical theory of cosmic perfection.

The Father is the sole origin of all things. He is the origin of the Son and the Spirit as Their begetter and source, coeternal, co-infinite, limitless, coessential and undivided. He is the origin of created things, as the one who produces, provides for, and judges them through the Son in the Holy Spirit.
The Philokalic text articulates the patristic Trinitarian cosmology in which the Father is the singular cosmological principle from whom all creation proceeds through Son and Spirit.

The difficulty of bringing the alchemical quaternity of elements into harmony with the Christian conception of the Trinity is yet another example of that common vacillation between three and four.
Von Franz, drawing on Jung, identifies the structural tension between Trinitarian (three) and quaternary (four) cosmological schemas as a recurring problem in both alchemy and depth psychology.

The three powers of my soul are my memory, my understanding, and my will. These three powers are 'the likeness to the Blessed Trinity in my soul' because 'in my one soul are three powers.'
Hillman cites the catechismal identification of the soul's three powers with the Trinity, foregrounding the anthropological and cosmological mirroring at the heart of Trinitarian psychology.

The world bears within it the image and, as it were, the reflection of the divine prototype... in their teaching on the creation of the world they affirm the existence of the divine prototypes of creation, in full accordance with the sophiological point of view.
Bulgakov's sophiology frames Trinitarian cosmology as the doctrine that divine prototypes, embedded within the Godhead, are reflected in created reality.

Gregory of Nazianzus had explained that the very incomprehensibility of the dogma of the Trinity brings us up against the absolute mystery of God; it reminds us that we must not hope to understand him.

Where the West began with the notion of God's unity and then considered the three persons within that unity, the Greeks had always started with the three hypostases and declared that God's unity—his essence—was beyond our ken.
Armstrong documents the East-West divergence in Trinitarian cosmological methodology, contrasting Latin unity-first theology with Greek hypostasis-first apophaticism.

The individual characteristics of the divine Persons are fatherhood, sonship, procession, and whatever else can be said of them individually.
The Philokalic text establishes the technical vocabulary — fatherhood, sonship, procession — that defines the personal distinctions within Trinitarian cosmological doctrine.

Jung elaborated fourness in a variety of works apart from alchemy — typology, dream interpretations, mandala symbolism, in distinction from Trinitarian thinking (CW 11).
Hillman notes Jung's deliberate juxtaposition of quaternary symbolism against Trinitarian thinking as competing cosmological and psychological schemas.

God, Who alone is without beginning, is Himself the Creator of all things, whether age or any other existing thing. And when I say God, it is evident that I mean the Father and His Only begotten Son, our Lord, Jesus Christ, and His all-holy Spirit, our one God.
John of Damascus grounds the cosmological doctrine of creation entirely within the Trinitarian formula, identifying the Creator with the threefold divine name.

The one engenders the two, the two engenders the three and the three engenders all things.
Edinger invokes the Taoist cosmological formula as a cross-cultural parallel to Trinitarian generative logic, situating the threefold structure as a universal cosmological archetype.

God of life. Its being is only a reflection and a mirror of the world of God... who is Tri-hypostatic and Almighty, and who through His Logos brought forth all things from non-being.
Palamas describes the Tri-hypostatic God as the creative agent who brings forth all things from non-being, situating the cosmological act within the Trinitarian structure.

It would therefore be dangerous to reduce the dogma of the Trinity and the problem of the fourth.
Von Franz warns against reducing the Trinitarian cosmological symbol to a functional schema, insisting on the irreducible tension between threeness and fourness.
