I have become [the church’s] servant by the commission God gave me to present to you the word of God in its fullness — the mystery that has been kept hidden for ages and generations, but is now disclosed to the saints. To them God has chosen to make known among the Gentiles the glorious riches of this mystery, which is Christ in you, the hope of glory. We proclaim him, admonishing and teaching everyone with all wisdom, so that we may present everyone perfect in Christ. To this end I labor, struggling with all his energy, which so powerfully works in me. My purpose is that [you] may be encouraged in heart and united in love, so that [you] may have the full riches of complete understanding, in order that [you] may know the mystery of God, namely, Christ, in whom are hidden all the treasures of wisdom and knowledge. I tell you this so that no one may deceive you by fine-sounding arguments. See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human wisdom and the basic principles of this world rather than on Christ. For in Christ all the fullness of Deity lives in bodily form, and you have been given the fullness of Christ, who is the head over every power and authority. Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of things that were to come; the reality, however, is found in Christ. Do not let anyone who delights in false humility and the worship of angels disqualify you for the prize. Such a person goes into great detail about what he has seen, and his unspiritual mind puffs him up with idle notions.

from Colossians chs. 1 and 2
