Colossians 2:19

and not holding fast to the Head , from whom the whole body , nourished and knit together through its joints and ligaments , grows with a growth that is from God .

They have lost connection with the head, from whom the whole body, supported and held together by its ligaments and sinews, grows as God causes it to grow.

And not holding the Head, from which all the body by joints and bands having nourishment ministered, and knit together, increaseth with the increase of God.
