Colossians 2:18-19

Do not let anyone who delights in false humility and the worship of angels disqualify you. Such a person also goes into great detail about what they have seen; they are puffed up with idle notions by their unspiritual mind. 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. 

Do not let anyone who delights in false humility and the worship of angels 
Colossians 2:23  Such regulations indeed have an appearance of wisdom, with their self-imposed worship, their false humility and the harsh treatment of the body, but they lack any value in restraining sensual indulgence.

disqualify you 
1 Corinthians 9:24-27  Do you not know that in a race all the runners run, but only one gets the prize? Run in such a way as to get the prize. Everyone who competes in the games goes into strict training. They do it to get a crown that will not last, but we do it to get a crown that will last forever. Therefore I do not run like someone running aimlessly; I do not fight like a boxer beating the air. No, I strike a blow to my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.
Philippians 3:13-14  Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.

They have lost connection with the head 
Ephesians 1:22-23  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.
Colossians 1:18  And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy.

from whom the whole body, supported and held together by its ligaments and sinews 
1 Corinthians 12:27  Now you are the body of Christ, and each one of you is a part of it.

grows as God causes it to grow 
Ephesians 4:15-16  Instead, speaking the truth in love, we will grow to become in every respect the mature body of him who is the head, that is, Christ. From him the whole body, joined and held together by every supporting ligament, grows and builds itself up in love, as each part does its work.
