+The moral basis of the doctrine.+--But it may be contended that these bare bones of the doctrine of the Trinity are not the doctrine as it enters into spiritual experience. I admit the fact while asserting strongly that but for this framework of intellectual necessity the doctrine would be unknown to faith and morals. It is sometimes stated that the doctrine of the Trinity was formulated in order to account for Jesus, but that is only incidentally true. Its framers took the materials for it over from Greek thought, and even Greek thought probably inherited it from an older civilisation still, if indeed there were any necessity to inherit it. I contend that if we had never heard of the doctrine in connection with Jesus, we should have to invent it now in order to account for ourselves and the wondrous universe in which we live. Unquestionably, however, it is from the point of view of religion and morals that the doctrine has most significance, and therefore has become indissolubly associated with the personality of Jesus; and it is easy to see how this has come about. Thinkers have always been compelled to construe the universe in terms of the highest known to man, namely, his own moral nature. It was natural, therefore, that while they thought of the universe as an expression of God, they should think of it as the expression of that side of His being which can only be described as the ideal or archetypal manhood. The infinite being of God is utterly incomprehensible to a finite mind, and in regard to it the most devout saint is as much an agnostic as the most convinced materialist. But we are justified in holding that whatever else He may be God is essentially man, that is, He is the fount of humanity. There must be one side, so to speak, of the infinitely complex being of God in which humanity is eternally contained and which finds expression in the finite universe. Humanity is not a vague term; we have already seen something of what it is. We ought not to interpret it in terms of the primeval savage, or even of average human nature to-day, but in terms of what we have come to feel is its highest expression, and that is Jesus. If we think therefore of the archetypal eternal divine Man, the source and sustenance of the universe, and yet transcending the universe, we cannot do better than think of Him in terms of Jesus; Jesus is the fullest expression of that eternal divine Man on the field of human history. Here, then, we have the first and second factors in the doctrine of the Trinity morally and spiritually construed.
