Colossians 2:18-19

Let no one defraud you of your prize [your freedom in Christ and your salvation] by insisting on mock humility and the worship of angels, going into detail about visions [he claims] he has seen [to justify his authority], puffed up [in conceit] by his unspiritual mind, and not holding fast to the head [of the body, Jesus Christ], from whom the entire body, supplied and knit together by its joints and ligaments, grows with the growth [that can come only] from God.
