Holy Hodor

The difference between science and religion, simply put, is that the former sees the ability to change your mind about what constitutes "the truth" as a virtue, and the other sees that same ability as a vice; one sees it as absolutely essential to survival in this world, while the other sees it as the path to eternal death and damnation in the next. 

Basically, this means that Christians think that all science, from anthropology to zoology and from astro physics to quantum mechanics, is either a complete lie  (which many Christians think is obvious from its over complexity), or simply mistaken to the very degree that it fails to confirm their "faith" in their God.  

As such, religion fosters a kind of 'seizure of the mind,' where people come together once a week to celebrate their collective refusal to change their mind about their ideas of God, and thus their understanding of the world over all, and especially themselves.  This is like people getting together to celebrate the fact that the engine in their cars have all seized up because they refused to change the oil. 

Christians champion the idea of refusing to change the oil in their mind about their religion, ironically enough, even though the world is perhaps just as infinitely complex as their God, and they are forever revising their understanding of God. And this we see when people not only change denominations within a religion, but also change or abandon religion altogether.

In fact, Christians are even always changing their mind about the nature of Christianity itself, which is evident from the over 40,000 different versions of it in America alone, each one of which claims to have finally gotten it in the way God intended us to get it all along.

Hell, when you add up the sum total of how many of their own "heretics" they had, Christians seem to disagree about the nature of Jesus, slavery, abortion, homosexuality, war, capital punishment, economics, politics, morality, and everything else! What alone seems to unite them all, interestingly enough, is their religious devotion to refusing to ever change their mind about why each and every  one of them should, and indeed even must, remain a Christian.

And the reason they are all convinced they must remain a Christian, is because they are afraid that if they did not, they would become as evil as it might be possible for them to be.  They don't see Jesus as the "spirit of love" that is trying to enter their hearts, since they are sure he is already there, but as the one holding the door closed, lest "churchyards yawn and hell itself breathes out Contagion to this world," as Hamlet put it, and "do such bitter business as the day would quake to look upon."

Jesus, in other words, is Hodor, to what the Christian fears lurks in their soul, and is just dying on a cross to get out.
