Pride maybe?
John 12:40 "He has blinded their eyes and hardened their hearts, so they can neither see with their eyes, nor understand with their hearts, nor turn--and I would heal them."
Matthew 15:14 Leave them; they are blind guides. If the blind lead the blind, both will fall into a pit."
Can’t see that or WON’T see that? My guess is they cannot tolerate the thought that their church can be wrong about anything since that would prove they are NOT infallible and EVERYTHING else they assert can also be wrong.
Try brain washing
