ABSTRACT
The purposes of psychological discussion the elaborate version contained in the Athanasian Creed would be sufficient, as this shows very clearly what Church doctrine understands by the Trinity. Nevertheless, a certain amount of historical explanation has proved unavoidable for the sake of psychological understanding. The author explains that his chief object, however, is to give a detailed exposition of those psychological views which seem to necessary if we are to understand the dogma as a symbol. Belief has already conquered the summit which thinking tries to win by toilsome climbing. The believer ought not to project his habitual enemy, doubt, upon the thinker, thereby suspecting him of destructive designs. Symbols that have an archetypal foundation can never be reduced to anything else, as must be obvious to anybody who possesses the slightest knowledge of my writings. To many people it may seem strange that a doctor with a scientific training should interest himself in the Trinity at all.
