“...Cerinthus embraced chiliasm, a form of apocalyptic vision that depicted the millennium as a physical and material period.”
Papais, one of the earliest church fathers we have anything from, clearly believed in a physical, earthly kingdom.

Later church fathers made the mistake of confusing the Church with the Millenial reign of Christ.
Or do you believe the Church father’s were infallable?
Why are you asking me this??
