4. The Religious Symbolism
The son is sent to Earth by the Father to give the people an ideal to strive towards, in the hope that humanity can better itself by following his example. Am I talking about Superman or Jesus? And thats not all: Superman is powered by the sun the light of the world, one of Jesus many nicknames; Superman stands for truth and justice you dont get much more true and just than the son of God. Furthermore, Superman loves humanity as a whole and saves everyone the Bible says anyone can be saved if they repent; and Superman is not only basically a demi-god himself (due to his immense power) but he is often illustrated in religiously symbolic poses i.e. images in All Star Superman include Superman sitting on a cloud, Superman holding the world in his hands, and dont forget Brandon Routh falling to Earth with outstretched arms (crucifix style) at the end of Superman Returns.
