ABSTRACT
The sequence of creeds illustrates the evolution of the Trinity idea through the centuries. In the course of its development it either consistently avoided, or successfully combated, all rationalistic deviations, such as, for instance, the so plausible looking Arian heresy. Psychology uses instead the concept of the unconscious, and specially that of the collective unconscious as opposed to the personal unconscious. People who reject the former and give credence only to the latter are forced into personalistic explanations. But collective and, above all, manifestly archetypal ideas can never be derived from the personal sphere. At any rate the documentary reports relating to the general projection and assimilation of the Christ-figure are unequivocal. There is plenty of evidence for the co-operation of the collective unconscious in view of the abundance of parallels from the history of religion. The self is defined psychologically as the psychic totality of the individual.
