In the 19th century came the time, in which the ordinary soul-activity that brought forth such significant results in natural science and technology, was also applied to theology. But what became of theology through this? Christ-Jesus, the incarnation of a Being that does not belong to the earthly became “the simple man of Nazareth,” looked upon indeed as the most perfect man, but not as the bearer of a super-earthly Being. Theology became naturalistic. The more our modern theologians look upon Jesus of Nazareth as a human being, the less they feel induced to pursue Christological ideas, and the happier they are! Even in theology they do not wish to rise beyond the description of the man, Jesus of Nazareth, they do not wish to rise to an understanding of Christ as a super-earthly Being that dwelt in the man, Jesus of Nazareth.
