Theology has always had a “narrative” shape to it. The problem with propositional or systematic theologies is not that they are non-narrative but that they have reduced the dense historical narrative of scripture to a bare sequence of cosmic-level events: creation → fall → redemption → final judgment. Theology then systematically expounds those events.
In this crude “meta-narrative” the story about Jesus has two parts to it. There is the “Jesus is God” story about the eternally existent Second Person of the Trinity, who at a certain place and time in history became incarnate of the virgin Mary; and there is the “Jesus is man” story about the Saviour who died on the cross to redeem humanity from sin and death, before returning to heaven.
