The authenticity of Constantine’s faith has been a matter of concerted debate. Some suppose that Constantine’s affection for Christianity was less a matter of revelation than it was of Realpolitik: he saw Christianity as a useful tool for controlling the empire. The reality is probably more complex. Constantine most likely had some devotion to one God in general and to Christ in particular. But Constantine perhaps admired the Christian God because he saw in this God a mirror of himself: one unrivalled and supreme lord of the world.
