"For in Christ all the fullness of the Deity lives in bodily form, and in Christ you have been brought to fullness." (Colossians 2:9-10)
Paul urges the Colossians to continue to live their lives in Christ, rooted and built up in him, strengthened in the faith they were taught, overflowing with thankfulness. He warns them: see to it that no one takes them captive through hollow and deceptive philosophy which depends on human tradition and the basic principles of this world rather than on Christ. For in Christ all the fullness of the Deity lives in bodily form, and in Christ you have been brought to fullness. The answer to every system that adds to Christ is this: he is already the fullness of God in bodily form, and in him you are already brought to fullness. Nothing can be added to what is already complete.
In him they were circumcised with a circumcision not performed by human hands but with the circumcision of Christ, having been buried with him in Baptism and raised with him through faith in the working of God who raised him from the dead. God made them alive together with him, having forgiven all their sins, cancelling the charge of legal indebtedness that stood against them and nailing it to the Cross. Having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the Cross. The Catechism identifies the Cross as the instrument of cosmic victory: in dying, Christ defeated the powers that held humanity in bondage and paraded them in the triumphal procession of his resurrection (CCC 550).
Therefore do not let anyone judge the Colossians by what they eat or drink, or with regard to religious festivals or new moons or Sabbath days. These are shadows of the things that were to come; the reality is found in Christ. Such regulations have an appearance of wisdom but lack any value in restraining sensual indulgence. The shadow-world of religion-as-performance dissolves when the substance, Christ, is present.
Brothers and sisters, in Christ you have been brought to fullness. Every system that offers you spiritual completion in addition to Christ has misunderstood the Colossian hymn. You are not incomplete. You are not lacking. In Christ you have the fullness of God in bodily form. Receive that fullness. Live from it. Stop searching for supplements to what is already complete.
Lord Jesus, in you all the fullness of God lives in bodily form. In you we have been brought to fullness. Cancel the record of our debts, nail it to your Cross, and let us live in the freedom of those who are complete in you. Through Christ our Lord. Amen.
