"The expectation of the end of the world and the coming of the Messianic Kingdom has nothing in it of a nature of a delusion, for it belongs to a world-view which was widely accepted by the Jews of that time, and was contained in their religious literature. Even the idea held by Jesus, that He was the One Who on the appearance of the Messianic Kingdom would be manifested as the Messiah, contains nothing of a morbid delusion of greatness. If on the ground of family tradition He is convinced that He is of the House of David, He may well think Himself justified in claiming for Himself one day the Messianic dignity promised to a descendant of David in the writings of the prophets. If He chooses to keep to Himself as a secret His certainty of being the coming Messiah, and nevertheless lets a glimmer of the truth break through in His discourses. His action, looked at solely from the outside, is not unlike that; of persons with a morbid delusion of greatness. But it is, in reality, something quite different. The concealment Of His claim has with Him a natural and logical foundation. According to Jewish doctrine the Messiah will not step out of His concealment until the revelation of the Messianic Kingdom. Jesus, therefore, cannot make Himself known to men as the coming Messiah. And if, on the other hand, in a number of His sayings there breaks through an announcement of the coming of the Kingdom of God made with all the authority of Him who is to be its King, that, too, is from the logical point of view thoroughly intelligible. Altogether, Jesus never behaves like a man wandering in a system of delusions. He reacts in absolutely normal fashion to what is said to Him, and to the events that concern Him. He is never out of touch with reality."
