Why does the the church suppress knowledge? There are a plethora of examples throughout the last two millennia, most notably Isaac Newton, Galileo Galilei, Voltaire, and Charles Darwin. Any time a new theory is presented that disagrees with the teaching of the church, the theory is mocked and it's creator is usually taunted, labelled a heretic, beaten, and may end up being brutally murdered (sadly this still happens today.) Then years later the theory is accepted by the church, as if it had always been.
We see this scenario play out time and time again. The church suppresses and denies these ideas because the idea may persuade some people to no longer believe their teachings; however looking back throughout history and seeing this scenario over and over again must surly persuade more people to stop believing then if the church had just accepted it in the first place.
