The tale of Batman is a journey that, in a way, could be read exactly like Jesus’.
Both of these heroes were born to an ugly, corrupt world, and in turn became the bringer of justice and redemption to their people.
There is one series of Batman movies, however, that highlights the idea of Batman as a Christ figure more so than any others, and that is Christopher Nolan’s The Dark Knight Trilogy.
“Bruce’s father is building a better world for the people of Gotham, yet it is up to his son, Bruce, to finish his work. Meanwhile, Batman’s good works are looked upon skeptically by the authorities and citizens of Gotham, though there are a few followers—especially children, such as Lieutenant Jim Gordon’s son—who see through the uncertainty and understand Batman for what he truly is. Batman’s debt to the Gospel stories seems indisputable [...] One of the questions Nolan struggles with is what it means to be a hero. A hero is obviously someone who fights for good and saves the day—but are not heroes also supposed to be beloved by those he or she serves? Bruce/Batman is certain he is helping the city, but the citizens are not so sure. Is he truly a hero, or simply an uninvited vigilante? Ultimately, Batman “becomes” what Gotham wants him to be—a criminal—by taking the wrap for Harvey Dent’s crimes because it is ultimately best for Gotham. One can’t help but be reminded of Jesus’ capture and trial by Pontius Pilate. When asked if he was the king of the Jews, Jesus’ only reply is, “You say so.” Christ did not protest when his people put him to death in the place of another criminal, because, after all, he was dying to save us from sin and death.” (https://www.americamagazine.org/issue/664/100/god-dark-knight)
Could Batman be seen as a Christ-like figure?
“Batman comics reveal Bruce Wayne lost faith in God after the death of his parents - and how he tried to find something else to believe in [...] Batman doesn't believe in God... at least not in a traditional sense [...] Bruce Wayne is an atheist, but that's a recent change, since Bruce just gave up the belief of his own personal god - Batman [...] he does explain that a deep belief in Batman saved him. Batman became the symbol of morality, goodness and faith in Bruce Wayne's world. In Bruce's own words, "God is above us. And he wears a cape." (https://screenrant.com/batman-atheist-dc-comics/)
Bruce considered Batman to be a God-like figure.
He crafted the role to represent “morality, goodness and faith,” after he had lost all of his.
He gave his life to Batman; working tirelessly day-in and day-out to bring peace and justice to Gotham City.
Batman did become the God to Bruce and all of the children he has collected over the years.
Batman is their saviour and justice is their religion. Nothing else really matters.
The Dark Knight movie also deals heavily with the struggle between good (Batman) and evil (The Joker), a very common theme found in Bible stories.
It seems as if Christopher Nolan had set out with the intentions to showcase Batman in a mythical-sense.
He wanted Batman to be viewed as the one true saviour of the city, and in doing so replicated Christian theology.
In fact many people believe that Nolan’s intention was to create a Christian propaganda film in the guise of a superhero/action film.
“The Batman trilogy of Christopher Nolan is a Christian allegory. Not just that - perhaps the best Christian allegory ever put to film. I first noticed this in The Dark Knight which magnificently portrays the political message of the Gospel : there is a people that need saving and the one person who is actually noble and just enough to save them is branded a murderer and expelled from the city.” (https://catholicveritas.com/blog/dark-night-rises-sacred-art)
To my knowledge Nolan has never confirmed nor denied this claim, so the world may never know if this film is truly the “best Christian allegory” ever made.
