"To us who regard [Jesus]as the unique revelation of God, the unfolding of the divine life under human forms, he is the ultimate standard of moral and spiritual life, the perfect expression of the will of God for humanity, the categorical imperative with a human heart. But very many who do not hold this belief in a formulated way or who feel compelled to deny it, including an increasing portion of our Jewish fellow-citizens, will still consent that in Jesus our race has reached one of its highest points, if not its crowning summit thus far, so that Jesus Christ is a prophecy of the future glory of humanity, the type of Man as he is to be. Christianizing means humanizing in the highest sense."
