Should a Christian blindly believe what they are told in church?
No, a Christian should never, never blindly accept what they are told in church. That is the very reason why so many strange and crazy doctrines proliferate, and make it all too bewildering for some people who just want to get right with God. All the confusion is a deliberate device of Satan attempting to keep people from knowing the word of God. False doctrines are his weapons, but they are wielded by “wolves in sheep’s clothing”. Yes it is definitely our duty as Christians, to test what we are told in church AND what we read here in this forum, to make sure it is in harmony with the Bible.
