In short, the answer is, “Yes.”
Now, I’m not saying that there aren’t things that we should be willing to concede among brothers & sisters in Christ, but we must be careful to hold to the truths of God’s Word.
So, what can happen if we don’t maintain that doctrine is important? I submit for example an excerpt from a message someone I know (I don’t think I need to be any more specific than that for this person’s sake & because ultimately it’s not important to this post) sent me a few days ago:
“We had a ‘church consultant’ come in today to help ‘healing,’ but instead of talking about forgiveness and things that would have been relevant, he talked about ‘woman speak’ and ‘man speak (of course, woman speak is the one where someone says one thing but means and expects another– you know, ‘No, you don’t have to get me anything,’ etc. So basically, women are manipulative liars, and men are the hapless, direct creatures that have to follow them around and guess). It was bad enough, until he actually started saying that this could be avoided in marriage by occasionally giving a flower– ‘Not even a rose! Just one single flower!’– on some day where your wife isn’t expecting it, and then you’re out of the dog house for a while. THEN he said that that’s how we should view Jesus: He commands certain things for us, but he actually wants different things from us, and we should guess what that is. Obedience isn’t enough for him to love you, and neither is love; it takes weirdly spontaneous action that no one can predict or understand.”
How do you ever come to a conclusion like this unless you have abandoned doctrine & God’s Word completely?!
Read the Word. Study it. Think about doctrine. Work through those things that you have questions about. Ask questions of wise men & women who have spent much time studying these things. Pray.
