Before I had read or understood much of the Bible, I refused to claim a denomination. I would simply state that I just believed the Bible. How I could believe it when I hadn't even read much of it is quite a mystery to me now. Later in life, I attended my first real Bible study on the book of Romans. The truths taught in that particular book were so contrary to what I had always "believed" that they caused me to wonder why I had never heard them before in my church. So, I began researching various denominations to discover what each of them believed. It was during this quest that I first discovered church doctrine. And so my thoughts on doctrine are this:
It is necessary for a church to take a particular stance on how they interpret scripture.
It is necessary for a church to hold fast to that stance despite the potential pull of the culture to sway them.
It is good for a church to belong to a denomination that shares their beliefs to hold them accountable.
It is good for a Christian to join a church whose doctrine they agree with so that they can fully submit themselves to church leadership.
Believing that the Bible is true is very good. Knowing what the Bible says and believing that it is true is even better. Learning to interpret scripture rightly (in light of scripture) is wonderful. Leaning on the written works of both living and glorified saints to better understand the word is marvelous.
