This supports the church because, in their eyes and in their church's eyes, anything other than absolute blind unwavering faith is sin. They take it as a good thing that they cannot be swayed by reason.

Remember, to devout Christians such as these everything in this world and all experiences in life are merely a test for their "true life" after death. They take nothing at face value, every single experience in their lives is viewed through the lens of their religion. If something does not support their beliefs it is considered a test by their god or an effort by their devil to sway them to sin.

There is a very very very skewed line between reality and fantasy for these people. They decide what is real and what is illusion, or what is true and what is untrue based not on sight, touch, smell, sound, or reason, but based on the rote dictation of their religious leaders.

In my opinion this is the true evil of religion. It detests independent thinking, espouses "choosing to believe" things (as opposed to being compelled to believe things based on sufficient evidence), and is diametrically opposed to the idea of rational inquiry integral to the scientific method.
