There is no denying the fact that Man of Steel was filled with religious themes, but the extent to which these allusions are portrayed might just give us some ques on what we might see in [Batman v Superman: Dawn of Justice](tag:711870).
Man of Steel:
In the beginning of Man of Steel, we witness a conversation between Kal-El's parents in regards to his future on Earth.
"You will give the people of Earth an ideal to strive towards. They will race behind you, they will stumble, they will fall. But in time, they will join you in the sun, Kal. In time, you will help them accomplish wonders.
"He'll be an outcast. They'll kill him.
"How? He'll be a God to them.
Already we can see a religious theme behind Kal-El's future. In the Bible, Jesus was depicted as an outcast for his actions, however, Jesus was also illustrated as a superhuman for his God-like abilities to make miracles happen. Moreover, after Kal-El's descent to Earth, (which is similar to Jesus' arrival into Mary's womb) he is found and fostered by the Kent family; a righteous and trustworthy family. Constantly throughout Clark's childhood, he is warned by his father not to use his abilities to help people in fear that Clark will be shunned or experimented upon.
"When the world find out what you can do, it's gonna change everything...People fear what they don't understand"
"It's a huge burden for anyone to bear; but you're not just anyone, Clark, and I have to believe that you were... that you were sent here for a reason...You're gonna have to make a choice, a choice whether to stand proud in front of the human race or not"
Likewise, Jesus was looked down upon by most of the people when they discovered the many wonders he was capable of. Sure he was able to have some loyal followers (which I will get into later), but he received heavy criticism for his unorthodox approaches. Now, later on in Man of Steel, we are introduced to General Zod who embodies Satan accordingly since he tempts Superman to give up on humans; his mission to help them. Superman and Jesus overcome the obstacle/temptation in their own way. Now this is only the first part of the story for Superman though because MoS did not fully explore the public's reaction. This is where Dawn of Justice comes in and based on the trailer that we saw I believe the movie will dwell upon allusions on Jesus' last days before his death.
So what can we expect from Dawn of Justice?
The DoJ trailer has introduced us to the public controversy Superman has created; most of which is negative:
"We as a population on this planet have been looking for a savior"
"We know better now, don't we? Devils don't come from hell beneath us. They come from the sky"
"The world has been so caught up with what he could do, that no one has asked what he SHOULD do"
"Go home, go home, go home, Go HOME"
Scribbled on a statue of Superman: False God!
In some scenes we see a positive aspect of his arrival, while in others, like the one in the beginning we witness the public's disapproval of him (especially Batman). This is a perfect manifestation of Jesus' unwanted ascension to fame. Both Superman and Jesus want to help humans, but each of them suffer from the fact that humans are not so trusting and fear what they do not understand, hence Batman's hesitation to welcoming Superman.
Therefore, considering all this, I believe Superman will forgo a battle (in order to protect humans) that will place him at the pinnacle of death. In doing, this will ensue the trust in Superman the people of Earth will have. This is all based on Jesus' death and resurrection which succeeded in gaining the faithfulness people needed to have in him.
