Jesus is Head of the Church
The church has no organization on earth larger than a local congregation, which consists of Elders/bishops, deacons and members/saints.
1 Paul and Timothy, bondservants of Jesus Christ, To all the saints in Christ Jesus who are in Philippi, with the bishops and deacons:
– Phil. 1:1, NKJV
Anything larger is an innovation of man, and in conflict with God’s revealed plan.
