When in Rome, the office of Pontifex Maximus was reserved for the emperor, failure to worship him as a god was sometimes punished by death, as the Roman government sought to link emperor worship with loyalty to the Empire. Many Christians and Jews were persecuted, because it was against their beliefs to worship the emperor.
Catholic Christianity, as opposed to Arianism and other heretical and schismatic groups, was declared to be the state religion of the Roman Empire on February 27, 380 by the decree De Fide Catolica of Emperor Theodosius I.
