This debate is a good demonstration of how blind faith works.
The church (not god), arrives at a conclusion and it is set in stone. From this point forward, those that believe it are blessed and those that question it are called heretics and suffer. This continues for centuries.
Unlike normal organisations, like businesses that have to adapt and justify their existence, the church expects all those around to change and adapt, whether they agree or not.
The believers like it this way because they don't like change. They want something solid, even if it's demonstrably wrong. They would rather die in unquestioning ignorance than explore their own beliefs because to do so would take them to places they are uncomfortable. They don't want to experience how it feels to have their faith shaken because it scares them. It is far easier to have someone else do the thinking for you
