Denial of the special creation of humanity jeopardizes the doctrine of Christ's federal headship. There is universal, indiscriminate, divine benevolence this side of the consummation. It is true both that we are the image and we possess it. The image consists in our rational, emotional faculties, and in our bodies. The image is restored only by union with Christ.
