Christ would never have made the impression He did on His followers if He had not expressed something that was alive and active in their unconscious. Christianity would never have spread through the pagan world with such astonishing rapidity had its ideas not found an analogous psychic readiness to receive them. It is this fact which also makes it possible to say that whoever believes in Christ is not only contained in Him, but that Christ then dwells in the believer as the perfect man formed in the image of God.
