The local church body is composed of one body with many members all of whom are in vital relationship with Jesus Christ, but the body also has "joints of supply," units of control, and unity, i.e., church leaders (Eph. 4:16). This together suggests body participation under the headship of the Lord Jesus Christ with leadership direction, submission and a authority in a two-directional manner.
First, the local government is invested in the body of believers who compose the local body under the headship of Jesus Christ according to the Word of God and the ministry of the Holy Spirit (Matt. 18:20; Eph. 1:22-23; 4:16; 5:21; Col. 1:18; 2:19).
Second, executive authority or leadership, however, is invested by the congregation, as authorized by Scripture, in a Board of Elders who lead the church and to whom the congregation is to submit under the headship of Christ. These men have the authority and responsibility to delegate to individuals, committees or other boards (as a Board of Deacons) authority and responsibility to carry out the business or ministry of the church in spiritual and physical (material) matters (Acts 20:28; 15:6; Eph. 4:11-12; Phil. 1:1; 1 Thess. 5:12-13; Heb. 13:7, 17).
In using its delegated authority, and in making its decisions, the Board of Elders must seek to be guided by the Scripture, the ministry of the Holy Spirit, and by input from the congregation (Acts 20:32; 6:2-5a; 11:22; 15:22; 2 Cor. 8:19).
