I think I understand the "heart" of the OP. God's truth cannot be copyrighted, nor all His deeds fully contained in one book. And if I apply a name to something He's said or done, it better be accurate and have His truth written all over it; otherwise, I can make the Word of God of no effect by my traditions, and shut out anyone in condemnation and judgment that doesn't agree with my doctrines or creeds.
However, M7:9, no need for "you all" to be scary. Not all think the same. On the other hand, neither need we all shun any type of labels or doctrine. In fact, IMO, it's impossible. As Bob Dylan sang, you gott'a serve somebody. We can't even communicate without labels, and any stated principle/position is a doctrine. I haven't looked or thought it through, but "bet" I could go through and come up with a pretty good list of things Jesus labeled and/or presented as "doctrine".
PERSONALLY, I may not use all the definition shared from a Baker's Evangelical Dictionary of Biblical Theology. I agree with some of it, some of it I believe is overstated and has at least inklings of mainstream orthodoxy. Again personally, I find the following definition to be more accurate, less loaded with orthodox dogma. Doctrine; teaching, instruction; something that is taught; a principle or position or the body of principles in a branch of knowledge or system of belief
. Even the "system of belief" part can give me pause, but I think it depends on what is the system and what is the belief that's really important. If it's a system of belief of Nazi rule, then I think that's a problem. If it's a system of belief that says "Jesus is God's Son, He did all the Father asked, and we are to learn what that is and follow in His footsteps", then I'd say that's exactly the system of belief we are to cling to, and some of the soundest doctrine there is.
Labels and definitions are part of our language. Necessary. Also though, hopefully used accurately, factually, correctly, truthfully. I admit I've never fully understood the statement, but Paul taught us there's nothing evil of itself. A label, or a doctrine, or a color, or an object - is. It is what it is. Good and bad can be descriptions, labels, judgments. Holy is the truth, but it's also a name, a label. The truth can be a statement, a belief, a thought, a doctrine.
As Martin said above, we are clearly told in scripture to contend for sound doctrine. Not only is there nothing wrong with that, we're told to do it. The following could be my creed; I believe in Jesus Christ, He is the Son of God. God will reconcile all to Himself, and He will be All in All.
Is that wrong, or do you believe it to be true as well? If so, IMO, you believe in those sound doctrines (teaching, instruction; a principle or position
We can often go too far one way or another. I can become so labeled, "creeded" and denominationalized, that I fit everything into such a box as to have no room for further thought, freedom, or fellowship. On the other hand, I can be so against labels, creeds, or groups that I have no room for further thought, freedom, or fellowship. I can fall in a ditch on either side of the road, thus being unable to move out of my own confines of the way I think or view things. And I can be just as wrong in saying "I can't stand Christians" as I can in saying "I am a Christian". In the former frame of mind I can set myself up as a judge and be hyper-critical and condemning (done it); the latter, I can go on crusades and kill people if they won't join my "church". Words are important. But it's not simply in the words I use. It's also in the spirit of the words, the accuracy of the words, whether they line up with THE Word; and how I live those words - bottom line, if I love God with my whole heart and my neighbor as myself.
If I do, then I can call myself a Christian, a believer, or a follower of Jesus. I can say I believe in UR, the Victorious Gospel, Christian/Biblical Universalism, or simply that God will save all. I can say my hair is brown, my eyes are blue, and my doctrines are to believe on Jesus, proclaim the Good News, lean not to your own understanding, love the Lord your God with all your heart and Him only serve. None of these things are bad in and of themselves. In fact, I would argue, none of them are bad at all, rather, they are exactly what we are to do. Sound doctrines. And my hair really is brown and my eyes blue.
Believe it or not, that's how I see it. And whether you do or not, another doctrine I believe is that I am to love you and live peaceably with you as much as is possible.
