I spent most of my life as a Methodist before my conversion. Although the Church was Methodist, we didn't necessarily have much interest or understanding of the national denomination. It was really just a small, rural bible based Church that happened to have been started by Methodists. It was a great place to spend my teen and early adult years!
I don't think Paul is advocating denominations in this passage. In fact, he warns against following different leaders and speaks of THE church as being the pillar and foundation of Truth. I think he is speaking of the different functions within the Church.
