“Until the interventions of the Roman emperors Constantine and Theodosius in the 4th century, there wasn’t one right, orthodox, or catholic (i.e., universal) expression of the faith. But eventually, one version of Christianity—Paul’s version focusing on the resurrected “Christ” as opposed to the historical Jesus—was endorsed by the power of the Roman Empire. After that, multiple Christianities disappeared. Suddenly, there was only one correct version sanctioned by the Roman state.”
