There is a multi-layered and, I think, fascinating relationship between the Jerusalem temple, Jesus' body, and the Church (and we could add, the Pauline conception of the New Creation). At different places in the NT Jesus' body is referred to as or associated with the temple. Paul repeatedly calls the Church Jesus' body and also the temple or house of God. One aspect of the relationship between Jesus' physical body and the temple that should be pointed out is that both were appointed by him to be torn down. The Church is God's rebuilt temple/resurrected Body, a temple/body not made with hands. These theological associations underscore the cosmic significance of the church and should help us to better grasp the seriousness of our getting along with one another in the Church. Paul's ubiquitous exhortations for the churches to live in harmony with one another can't be interpreted without this thicker biblical theological perspectve or they will sound (to me) like so many urgings to be nice.
