In all this Luke is undoubtedly preserving the authentic quality of primitive Christianity. If he had been disposed to read back into the age he was describing the characteristics of the age in which he wrote, we should presumably have had from him a story of a mission planned and directed from Jerusalem by the Twelve. But of such ecclesiastical theory there is not a trace in his narrative.
