representative; although already at the time of Paul it was the custom to represent the self-sacrificing God only by an effigy, instead of a real man. The important point, however, was not this, but the idea which lay at the foundation of this divine self-sacrifice. And this was not affected by the victim's being a criminal, who was killed in the rôle of the guiltless and upright man, and by the voluntariness of his death being completely fictitious. Might it not also be, as the believers in Jesus asserted, that the Messiah was not still to be expected, and that only on the ground of human righteousness; but that rather he had already appeared, and had already accomplished the righteousness unattainable by the individual through his shameful death and his glorious resurrection? The moment in which this idea flashed through Paul's mind was the moment of the birth of Christianity as Paul's religion. The form in which he grasped that conception was that of an Incarnation of God; and at the same time this form was such that he introduced with it quite a new impulse into the former mode of thought. According to the heathen conception a God did indeed sacrifice himself for his people, without thereby ceasing to be God; and here the man sacrificed in the place of God was considered merely as a chance representative of the self-sacrificing God. According to the old view of the Jewish faith it was really the "Son of Man," a being of human nature, who was to come down from heaven and effect the work of redemption, without, however, being a real man and without suffering and dying in human form. With Paul, on the contrary, the stress lay just on this, that the Redeemer should be himself really a man, and that the man sacrificed in God's place should be equally the God appearing in human form: the man was not merely a representation of God's as a celestial and supernatural being, but God himself appearing in human form. God himself becomes man, and thereby a man is exalted to the Deity, and, as expiatory representative for his people, can unite mankind with God. [332] The man who is sacrificed for his people represents on the one hand his people in the eyes of God, but on the other hand the God sacrificing himself for mankind in the eyes of this people. And thereby, in the idea of the representative expiatory victim, the separation between God and Man is blotted out, and both fuse directly in the conception of the "God-man." God becomes man, and by this means mankind is enabled to become God. The man is sacrificed as well in the place of God as in that of mankind, and so unites both contradictories in a unity within himself.
