Colossians 2:19

Colossians 2:19 And not holding the Head, out from whom all the Body, being richly supplied and knit together by means of the joints and sinews, grows with the growth of God.

Since Christ is the Head of the Body, we have to hold the Head. Holding the Head is acknowledging that only Christ is the Head; it is coming absolutely under His authority. We can be joined to the brothers and sisters only when we hold the Head. Te ,ebers of the Body are fitted together and able to live the Body life through holding the Head. Our relationship to the Head determines our relationship to the other members. All the questions regarding our relationship with the brothers and sisters can only be solved when we come under the absolut authority of the Lord. Unless we recognize the headship of Christ in the Body, we will never have a perfect fellowship with the other members, because it is our common relationship to Him that causes us to be related to one another. 

Apart from Christ, we have no means of fellowship. When we do not hold the Head, our fellowship becomes invalid. The basis of our fellowship is our mutual holding of the Head. When we all hold the Head, we will hold to one another, and our relationship with the Body will be proper.
