11. From Jesus to Christ
From a spiritual contemplation of the whole evolution of humanity we can, through spiritual science, come to a recognition of Christ, and through Christ's own nature we can recognize that He once must have lived in a human body. Spiritual-scientific investigation necessarily leads to the historical Jesus. Indeed, it is possible to indicate with mathematical precision when Christ must have lived in the man Jesus, in the historical Jesus. Just as it is possible to understand external mechanical forces through mathematics, so is it possible to understand Jesus by regarding history with a spiritual vision that encompasses Christ. That Being Who lived in Jesus from his thirtieth to thirty-third years gave the impulse humanity needed for its development at a time when its youthful forces were beginning to decline.
