He took up the Lutheran tenets precisely where he had left them, but, no longer a child, he was forced to criticize what he had once felt, and he set himself to rationalize Lutheran theology and such elements of catholic theology as had survived through Luther. In this he was not always so successful as he imagined. His doctrine of the Trinity, that Jesus Christ is the One God and that the Trinity is in Him, gets over an arithmetical difficulty, but finally leaves the imagination baffled, trying to make out how Jesus carried on the government of the universe while He lay a helpless infant in the manger or His mother's arms. His reaction against all outside views of Christ's death, imputed righteousness, and faith only, was more successful, but not new, since in this the quakers in England and Jacob Boehme were before him. Nor was his contention that love was the supreme good new to those who had read through the New Testament. His doctrine of uses was merely a theological variation of that utilitarianism which is inseparable from rationalism, and which casts over everything a drab veil that only the artist can remove. He is really at his best when he expatiates on love and wisdom. Love corresponds with the heart, wisdom with the lungs. As the heart sends the blood to the lungs, where it is purified by the oxygen, so love feeds the understanding, and is in turn purified by it. Swedenborg's perception of wisdom begotten of love inspired his best passages and gave them their authentic import.
Swedenborg gazed inwards so intently that after an initial period of unrest, terrors, and nightmares his inner eye opened, and he saw into the realities of the inner world. For the moment I take his word for it, and will question later on. His open eye saw into heaven and hell, gazed into the faces of angels and of God, and his opened ear heard the angels speaking things he could understand and utter. At once he rationalized. He stripped even the celestial angels of all mystery as well as of garments, and traced them back to an earthly pedigree. Angels are men, and when they talk they are no more interesting than the elders of a Lutheran congregation. God also is a man--not, be it observed, the Man of a crude anthropomorphism, but infinite, omnipotent Man, from Whom each man, created in His image (will) and likeness (understanding), draws his real manhood. He carried this doctrine into his rationalized version of the Incarnation. Christ assumed human nature in the womb of the Virgin, and by His conquering life put it off, replacing it by the Divine Humanity. The last phrase has accomplished yeasty work in modern religious thought. How many are aware of its origin?
