A few years ago I had a poster hanging in my office with the caption "Let there be such oneness among you that one cries the rest taste salt."  The church, which is supposed to be Christ's body, is so constituted that the life of one member is intertwined with the lives of all the others.  This is beautifully demonstrated in the Holy Communion where we are symbolized in one loaf and one cup. Division and an inability to allow for differences is destroying denominations and local churches.  Since the earliest days of the New Testament Church this has been the down fall of the church.  If we could truly be "One in the Spirit" and see ourselves as one cup the kingdom might have been established eons ago.
