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.
The driving forces that work themselves out in this thinking are not conscious motives; they spring from an historical occurrence rooted, in its turn, in those obscure psychic conditions for which one could hardly find a better or more succinct formula than the “change from father to son,” from unity to duality, from non-reflection to criticism.
To the extent that personal motives are lacking in trinitarian thinking, and the forces motivating it derive from impersonal and collective psychic conditions, it expresses a need of the unconscious psyche far surpassing all personal needs.
This need, aided by human thought, produced the symbol of the Trinity, which was destined to serve as a saving formula of wholeness in
an epoch of change and psychic transformation.
Manifestations of a psychic activity not caused or consciously willed by man himself have always been felt to be daemonic, divine, or “holy,” in the sense that they heal and make whole.
His ideas of God behave as do all images arising out of the unconscious: they compensate or complete the general mood or attitude of the moment, and it is only through the integration of these unconscious images that a man becomes a psychic whole.
The “merely conscious” man who is all ego is a mere fragment, in so far as he seems to exist apart from the unconscious.
But the more the unconscious is split off, the more formidable the shape in which it appears to the conscious mind—if not in divine form, then in the more unfavourable form of obsessions and outbursts of affect.
Gods are personifications of unconscious contents, for they reveal themselves to us through the unconscious activity of the psyche.
Trinitarian thinking had something of the same quality, and its passionate profundity rouses in us latecomers a naive astonishment.
We no longer know, or have not yet discovered, what depths in the soul were stirred by that great turning-point in human history.
The Holy Ghost seems to have faded away without having found the answer to the question he set humanity. ~Carl Jung, CW 11, Para 242
