Yet Christians did not feel that God was entirely unknowable. The man Jesus had been an image (eikon) of the divine and had given them an inkling of what the utterly transcendent God was like. They were also convinced that, in spite of everything, they had entered a hitherto-unexplored dimension of their humanity that in some sense enabled them to participate in the divine life. They called this Christian experience theosis (“deification”): like the incarnate Logos, they too had become the sons of God, as Paul had explained.
