V. Jeshu ben Pandira I

From the worlds we have mentioned proceed those forces which penetrate into our lives. Here we have to point out that, in the epoch which lies behind us, human beings were primarily dependent upon influences from the physical world, primarily capacitated to receive impulses out of the physical world. This lies behind us as the Greco-Roman epoch. During this epoch Christ worked on earth in a physical body. Since the human being was then enabled primarily to receive the influences of the forces existing in the physical world, Christ had to appear on the physical plane.
