In 380, mainstream Christianity–as opposed to Arianism–became the official religion of the Roman Empire.[61] Christianity became more associated with the Empire, resulting in persecution for Christians living outside of the empire, as their rulers feared Christians would revolt in favor of the Emperor.[62] In 385, this new legal authority of the Church resulted in the first use of capital punishment being pronounced as a sentence upon a Christian 'heretic', namely Priscillian.[63]
