Is it sinful to criticize Christianity?Many may say it's okay for a Christian to, e.g. read some atheist books for curiosity, books like Richard Dawkin's The God Delusion.
Is it sinful to doubt Christianity and try to explore other truths?
Is it sinful to attempt to try solidify your faith by opening it up to interrogation, even if by doing so there is a risk you may lose your faith?
But I think I have found a pastor who believes that this is not the case. Listen to this guy: Should Christians Watch Movies?
This guy argues that Hollywood movies are filled evil worldly and sinful things (e.g. violence, sex, materialism, etc), so much so that we should not even watch them because they will fill our mind with sinful thoughts, and sinful thoughts can cause us to become sinful ourselves. This idea seems to be backed up by the bible. Philippians 4:8 says, "Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable--if anything is excellent or praiseworthy--think about such things."
So if it is forbidden for a Christian to watch movies then why wouldn't it be forbidden for Christians to read atheist books?
