To be perfectly clear I want to say this:
I do not believe perfect doctrine is essential. I am well aware that some things that I believed after I was born again are different/out and out opposed to what I believe now.
I could spend and eternity of eternities learning about the Lord, His character, what He does, how He does it, etc. I could spend an equally long time learning and being awed by the work of Jesus Christ on the cross. Learning the truth is an ongoign process.
And I am also well aware that a person can be right about doctrinal points and be lost.
However, I will not submit to the following ideas:
1) Doctrine is unimportant or only marginally important.
The bible says several times that truth is important or that doctrine is important and that it does indeed matter.
2) A Christian should not pursue right doctrine (also known as TRUTH) because all that really matters is that they are saved.
This is a very narrow view of eternal life. Eternal life and the truth may not be fully realized until we are resurrected, but that doesn't mean that we should toss doctrine to the wind.
3) A person can have a perfect working theology and still be lost.
If their theology was right, then they would know they needed the Lord and that it is only through Christ can we have hope of salvation and they would be driven to repentence and faith.
4) That all we need is Jesus and to love Him and one another.
That certainly is the most important thing, to love the Lord and love others. That doesn't mean everything else is unimportant, especially the pursuit of Truth.
5) That if doctrinal differences of relative importance arise among believers, that they should respect one another's opinions and not argue about them.
I agree with this one, but it is missing something of vital importance--going to the throne of God and seeking Him to lead us into truth. It can be done. It should be done. It must be for the sake of the church. Only this way will ever have a chance at really separating the truly unimportant things from those things that are really important. If we claim to be brothers and we disagree on an issue, we should hit our knees and seek the Lord.
6) Doctrine is divisive.
Absolutely not! True doctrine is not divisive amongst the children of God. Pride, hard-heartedness, false teachings, and false converts mixed with believers are divisive. Let me adapt a saying that you commonly hear: Doctrine doesn't divide people. People divide people.
As far as importance goes, anything that doesn't help produce a sincere faith, love for the bretheren or a clear conscious is not worth arguing over or even discussing.
There are other things that I might could put on here, but that is enough for now, I think.
