In The Bloudy Tenent, Williams points out that Constantine "did more to hurt Christ Jesus than the raging fury of the most bloody Neroes." at least under the Christian persecutor Nero, who was rumored to have had the Apostle Paul beheaded and Saint Peter crucified upside down, Christianity was a pure (if hazardous) way of life. But when Constantine himself converted to Christianity, that's when the Church was corrupted and perverted by the state. Williams explains that under Constantine, "the gardens of Christ's churches turned into the wildernesss of national religion, and the world (under Constantine's dominion) to the most unchristian Christendom." Legalizing, legitimizing the Church turned Christianity into just another branch of government enforced by "the sword of civil power," i.e., through state-sponsored violence.
