The core of Classical Christianity is the mystery of the Incarnation: God coming in the flesh. This is not a “spiritual manifestation” as Gnosticism would posit, no his appearing was as ordinary and messy as all our appearings. Yes the Angels sang and the shepherds gaped. The Wise Men were latecomers. In the end the event was self-organizing as it was an organic ordering of protoplasm not a abstraction of whimsy.
