In this change of Imperial formula Constantine acknowledged his responsibility to an earthly realm whose discord and conflict might arouse the "ira deorum"; he also recognised the power of the new Christian priestly hierarchy in determining what was auspicious or orthodox. Though unbaptised, Constantine had triumphed under the "signum" of the Christ (probably some form of Labarum as an adapted or re-interpreted legionary standard). He may have officially ended – or attempted to end – blood sacrifices to the "genius" of living emperors but his Imperial iconography and court ceremonial elevated him to superhuman status. Constantine's permission for a new cult temple to himself and his family in Umbria is extant: the cult "should not be polluted by the deception of any contagious superstition". At the First Council of Nicaea Constantine united and re-founded the empire under an absolute head of state by divine dispensation and was honoured as the first Christian Imperial "divus". On his death he was venerated and was held to have ascended to heaven. Philostorgius later criticised Christians who offered sacrifice at statues of the "divus" Constantine. His three sons re-divided their Imperial inheritance: Constantius II was an Arian – his brothers were Nicene.
