Authority in the Church
Christ - The Head of the Church
Christ is the Head of the Church, which is His body. He is the source of all that the Church is and does. His glory is the objective of every action and function of His body. His recognized as the head over all things including His Church.
And God placed all things under his feet and appointed him to be head over everything for the church, which is his body, the fullness of him who fills everything in every way.
The Word of God - The Guide of the Church
God has provided His Word to guide and direct His Church. It contains everything necessary to lead the Church, including His words, counsel and purpose for the Church and every believer.
All scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work
2 Timothy 3:16-17
The Holy Spirit - The Power of the Church
The Holy Spirit is the source of all power in the Church. The Holy Spirit interprets God's teaching to the Church and to each individual believer.
But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.
