Christ the Medium
Wolfhart Pannenberg, in his book Metaphysics and the Idea of God, concludes that Jesus is the solution to the over-abstraction of the concept of God by modern philosophy. Jesus is concrete. He is real and actually existed in history as the Principium of all creation. Pannenberg did not say anything new by employing this argument for the reality of Truth in Christ. St. Bonaventure said the same thing in the 13th century. According to him the Idea of God is the Word who is Jesus. For the Father to know himself is for him to know the Word and the Spirit. Because the Ideas of all things find their unity in the Word for God to know his creation is to know his essence as it exists in the mirrored form in creatures.
When the Word took on flesh he fulfilled the role of medium between creation and God. He is the ultimate convergence between phusis and Theos. Men therefore can have knowledge through the illumination brought through the image of the Word inherent in him. But of course true knowledge comes through faith and the indwelling of the Word Jesus Christ in the believing person. The hypostatic working of Christ’s human mind with the divine is the Exemplar of the mind of the redeemed man. The church has the mind of Christ (1 Cor. 2:16). Pannenberg uses a form of Medieval Exemplarism following in the reappropriation of neo-Platonism by St. Augustine and its continuation by Anselm, Bonaventure, Aquinas, et al against the radical Hegelian and Heideggerian fissure between theology and philosophy.
