Colossians 2:18 (King James Version)
18Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,

II. He cautions them to take heed of those who would introduce the worship of angels as mediators between God and them, as the Gentile philosophers did: Let no man beguile you of your reward, in a voluntary humility and worshipping of angels, v. 18. It looked like a piece of modesty to make use of the mediation of angels, as conscious to ourselves of our unworthiness to speak immediately to God; but, though it has a show of humility, it is a voluntary, not a commanded humility; and therefore it is not acceptable, yea, it is not warrantable: it is taking that honour which is due to Christ only and giving it to a creature. Besides, the notions upon which this practice was grounded were merely the inventions of men and not by divine revelation,—the proud conceits of human reason, which make a man presume to dive into things, and determine them, without sufficient knowledge and warrant: Intruding into those things which he hath not seen, vainly puffed up by his fleshly mind—pretending to describe the order of angels, and their respective ministries, which God has hidden from us; and therefore, though there was a show of humility in the practice, there was a real pride in the principle. They advanced those notions to gratify their own carnal fancy, and were fond of being thought wiser than other people.
Pride is at the bottom of a great many errors and corruptions, and even of many evil practices, which have great show and appearance of humility. Those who do so do not hold the head, v. 19. They do in effect disclaim Christ, who is the only Mediator between God and man. It is the highest disparagement to Christ, who is the head of the church, for any of the members of it to make use of any intercessors with God but him. When men let go their hold of Christ, they catch at that which is next them and will stand them in no stead.—From which all the body, by joints and bands, having nourishment ministered, and knit together, increaseth with the increase of God.
Observe, 1. Jesus Christ is not only a head of government over the church, but a head of vital influence to it. They are knit to him by joints and bands, as the several members of the body are united to the head, and receive life and nourishment from him. 2. The body of Christ is a growing body: it increaseth with the increase of God. The new man is increasing, and the nature of grace is to grow, where there is not an accidental hindrance.—With the increase of God, with an increase of grace which is from God as its author; or, in a usual Hebraism, with a large and abundant increase.—That you may be filled with all the fulness of God, Eph. 3:19. See a parallel expression, Which is the head, even Christ, from whom the whole body, fitly joined together, maketh increase of the body, Eph. 4:15, 16.
