In the words of J.A.T Robinson:
"The New Testament says that Jesus was the Word of God, it says that God was in Christ, it says that Jesus is the Son of God, but it does not say that Jesus was God, simply like that" (Honest to God, page 70).
Paul Tillich has also observed that the traditional doctrine of the Incarnation can be regarded as "inadequate" since:
"'nature' in the Greek sense implies a static essence. Two such essences cannot be joined together to create one whole person" (See Daniel Day Williams' What Present-Day Theologians Are Thinking, page 133).
