The religious policies of Constantius II were a mixture of toleration for some pagan practices and repression for other pagan practices. He also sought to advance the Arian or Semi-Arianian set of beliefs, now generally regarded as heresy, within Christianity. These policies may be contrasted with the religious policies of his father, Constantine the Great, whose Catholic orthodoxy was espoused in the Nicene Creed and who largely tolerated paganism in the Roman Empire. Constantius also sought to repress Judaism.
