Ekklesia is an organic assembly of believers. It is totally different from the institutional church that has evolved over the centuries. It’s not a religion, a building, or a system of traditions and beliefs. Ekklesia is an assembly of believers who gather together under the headship of Jesus. It is the Body of Christ in action, not a weekly program or show for Christian spectators.
