If you are a Christian, you ought to worry about what they believe, because they damn people to hell with their teachings. It is a Christian’s duty to be well armed against the enemy of souls.
because they damn people to hell with their teachings.
But there is only one who can send us to hell.
Matthew 10
28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
