The Christianity that entered the Roman Empire was not the disruptive message Jesus taught in Galilee, but a reshaped faith the empire could use. The raw Synoptic ethic — reversal of status, rejection of hierarchy, inner transformation over obedience — was incompatible with imperial power. What survived was what could be adapted: creeds, offices, authority, and a cosmic Christ who stabilised the social order. Yet beneath these layers, the original voice still whispers through the Gospels, offering a vision of freedom no empire has ever been able to absorb.
