“The history which constitutes the being and existence of the human Jesus belongs to the history of God in the second of God’s modes of being (as ‘Son’). If, in Jesus Christ, God has elected to become human, then the human history of Jesus Christ is constitutive of the being and existence of God in the second of God’s modes to the extent that the being and existence of the Second Person of the Trinity cannot be rightly though of in the absence of this human history."[1]
