I love the picture of the church as the body of Christ. Each one of us is unique in our calling, gifting, and passions. We each have a distinct role to play so that the body can fully function. There is no hierarchy of body parts, just many parts, submitted under the headship of Jesus, working together for His purposes and glory.
When we start to think of ourselves as more highly than we ought, when we put ourselves above others, our passions and desire above others, forget that we submit to Jesus, or forget that we live for the glory of Jesus and not ourselves, we become fractured and minimize our impact on the Kingdom of God. As Christians who have been around the church for a while, this is not a new or revolutionary concept. We work hard to keep this perspective and live in unity within our churches. But could this picture be extended to the larger Church with a capital "C."
What I mean by this is can each church, each denomination bring with it their own unique passions, giftings and callings and be used by the headship of Jesus to run after a unique and specific ministry. On the surface, many of us would say, "YES!" But how we live, talk about, and interact with these other parts of the body of Christ would say, "NO!"
