It is not possible to understand the NT concept of the church if we overlook the numerous metaphors used to portray it. The church is Christ's body, a temple, a family, a royal priesthood, twelve tribes, the chosen race, Abraham's children, the new creation, the bride of Christ, and so on. Bible readers should be careful not to construct their theology of the church on a single metaphor.
