Divided we stand?

I have been recently thinking about the trouble we take to define ourselves inside the body of Christ. To see myself as part of a denomination is actually quite a grievous thing in the heart of God because I am dividing the body of Christ. It is one thing to use a functional term to define myself, for instance - I call myself a charismatic to declare that I believe in the charismata of the Holy Spirit but to label myself as a Pentecostal or a Brethren means that I am accepting an identity which is not accepted in heaven. I am accepting a way of life whether I subscribe to it fully or not. I am hindering fellowship with others in the whole body of Christ. I am allowing to world to know that we are divided. And worse, I am passing on a heritage to my children that is spiritually unhealthy. 
My slogan should be - I am a Christian, pure and simple. I may have an understanding of the Scriptures that may be different from other believers but I am not willing to form a boundary wall around it. May that attitude remain in me till the end.
