According to J. M. Robertson, Christianity and Mythology (London, 1900), the Christ-Myth is merely a form of the Krishna-Myth. The whole Gospel tradition is to be symbolically interpreted.
In the Catholic Church the study of the Life of Jesus has remained down to the present day entirely free from scepticism. The reason of that is, that in principle it has remained at a pre-Straussian standpoint, and does not venture upon an unreserved application of historical considerations either to the miracle question or to the Johannine question, and naturally therefore resigns the attempt to take account of and explain the great historical problems.
We may name the following Lives of Jesus produced by German Catholic writers:—
