Introduction
  Brief recap of setting (MAP), including pseudo-Christian  teachers who advocated certain religious practices as necessary for spiritual  maturity. Paul warns them against being  taken captive by these false teachers (read 2:8). He rejects these practices as hazardous to  their spiritual health because they will side-track them from spiritual  maturity.
  It should not surprise us that these religious practices are  central other world religions. But what  is stunning and tragic is that they have been common in most of Christendom for  the past 2000 years! It’s like most of  the church has never read this passage (and many others like it)! If you want to mature spiritually, you must  be able to identify these religious practices, resist those who advocate them, and  root them out of your own life. So the  tone of this teaching (like this passage) will be negative – but out of loyalty  to Jesus and love, not out of mean-spiritedness or superiority.
Ritualism
  Read 2:16. Paul is  referring to the rituals prescribed by God in the Old Testament. The dietary laws and the various holy days of  the Jewish calendar were part of a whole way of relating to God (centered  around offering sacrifices through priests) which was ritualistic. By ritualism, I mean relating to God primarily through prescribed rituals. The Colossian Christians hadn’t been  practicing these rituals – but the false teachers were judging them as  unspiritual for their non-practice, and they were wavering.
  
    Ritualism is a key component of virtually all major world religions except for biblical Christianity (EXAMPLES). Of course, many “Christian” denominations are  extremely ritualistic (EXAMPLES: liturgical service; religious calendar; sacred  spaces; etc.). 
  
  Why does Paul warn us against ritualism? The answer is found in the next verse (read  2:17). Ritualism is profoundly out of  synch with what God is doing because it focuses on the “shadows” instead of the  “substance” or “reality.” These rituals  were “shadows” of Christ. The whole Old  Testament ritual system was a divinely inspired multi-media presentation which  communicated pictures of God’s desire to dwell in His people (TABERNACLE), their  sinfulness which prevented this (BARRIERS & VEIL), and His future provision  of forgiveness through Christ's death which would make it possible for Him to  dwell in us (PRIEST & SACRIFICE).  God wanted His people to be constantly reminded of these central issues.
  
    But now the “shadows” have been fulfilled by the “reality” – a  personal relationship with God through Christ (1:27 – “Christ in you”). Paul makes this same point in Gal. 4:4-6  (read). Through His death, Jesus has  provided complete forgiveness and adoption into God’s family so we can be  indwelt by His Spirit and relate to Him personally as our “Abba.” The moment you receive Christ, God  permanently gives you these gifts. You  can relate to God wherever you are, secure in His love, sharing your problems  and joys, asking Him for the help you need, thanking Him for His involvement in  your life, etc. It’s not just that there  is now no need for ritualism; it’s that ritualism would interfere with the  development and enjoyment of your personal relationship with God.
    
      This is why there is such a dramatic change in the role of  ritual from before Jesus came to since He has come. There were hundreds of prescribed rituals for  God’s people in the Old Testament, but there are only two since His death and  resurrection (and one of these two – baptism – is done only once). There were detailed instructions on how to  practice the Old Testament rituals (because of their symbolic significance),  but there is very little instruction on how to practice baptism and  communion. So little, in fact, that the  church has tragically been fighting for centuries over how to practice them!
    
    This is why Paul goes on to say that for Christians to revert  to ritualism is not spiritual progress, but rather spiritual regression (read Gal.4:9-11). Imagine a girl separated from her father from  birth. She has only pictures of him,  which she treasures and looks at constantly.  Then he returns. Shouldn’t she  relate to the pictures differently now?  She wouldn’t hate them or throw them away, but she wouldn’t relate to  her father through them anymore. What if,  after she began to enjoy relating to him, she went back to relating to him  through her scrapbook??
  
  So avoid ritualism! It  profoundly misrepresents Christianity to the watching world, and it will impede  your spiritual maturity.
Mysticism
  Read 2:18. Here is a  second religious practice by which Christians are commonly drawn off the path  to spiritual maturity. Paul describes  certain people who were pronouncing them “second class citizens” because they  hadn’t had certain dramatic spiritual experiences. Evidently, these people had deprived  themselves of food or sleep, or had even beaten themselves (“self-abasement”) in  order to induce an altered state of consciousness. They had a so-called “vision” in which they  either worshipped angelic beings or witnessed angels worshipping God. Because they had this experience, they  claimed to have the “inside track” on God.  Evidently, they were telling the Colossians that unless they had similar  experiences they would remain spiritual pygmies.
  
    The most common name for this is mysticism. Mysticism is a  distortion/counterfeit of the personal relationship with God described  above. It is seeking dramatic spiritual experiences as a key to spiritual maturity. Mysticism is the dominant form of  spirituality in the West today.  Atheistic naturalism created a tremendous spiritual vacuum in people's  hearts (and discredited the Bible as an authoritative guide for knowing God). Now all kinds of mysticisms are rushing in to  fill that vacuum.
    
      EXAMPLES: Native American vision quests; Transcendental  Meditation; out-of-body experiences; New Age channeling and spirit-guides;  etc. Mysticism often uses ritualistic  and/or legalistic (see below) practices to induce dramatic spiritual  experiences.
      “Christian” mysticism also abounds (e.g., Toronto Blessing;  healer-dealers slaying people; insistence on speaking in tongues to be  Spirit-filled; etc.).
    
  
  What's wrong with mysticism?  Why was Paul so upset with it? It  wasn’t because God is against/never grants dramatic spiritual experiences to  His people. Paul had seen the risen  Christ at His conversion and several times since. He had been caught up in a vision to the  presence of God and heard things impossible and impermissible to describe  (2Cor.12:2-4). I’d say these  qualify as dramatic spiritual experiences! 
  
    One danger of mysticism is that thirsting for them can lead  you into spiritual deception. Demons can  deliver powerful spiritual experiences.  So if your goal is to have them, you can be led astray by whoever and  whatever delivers them (EXAMPLE).
    Another danger is that having genuine dramatic spiritual  experiences can lead you to think you are mature because you have them. But there is no biblical connection. The Corinthian Christians had all kinds of dramatic  spiritual experiences, yet Paul calls them immature because they lack the proof  of spiritual maturity – serving love (1Cor.13:1ff.). On the other hand, many Christians become  mature, loving servants of Jesus without ever having dramatic spiritual  experiences.
  
  What's the antidote to mysticism? Read 2:19. Paul’s critique of the mystics includes his  antidote.
  
    “Hold fast to the Head” means to build your relationship with Christ through the Bible. Paul restates this in Col.3:16 (read),  and he uses this same verb in 2Thess.2:13 (read). Mysticism leads us beyond/away from Christ’s  Word – but Christ meets us personally through His Word. (His Word also provides us with the basis for  discerning spiritual experiences.)
    “...being supplied and held together by the  joints and ligaments...” means to regularly allow other Christians to communicate His Word and love to  you (read Eph.4:14-16).  Mysticism leads to thinking that you are so close to God that you don’t  need His people. Biblical Christianity  leads to listening to God through His people as they bring God’s Word to us.
    The result of holding fast to Christ in this way is genuine  growth from God – gradual growth in your personal relationship with Him and in  your ability to love others!
  
Legalism
  Read 2:20,22. These  Christians were being told that it was wrong to eat certain foods – and  following these prohibitions was key to spirituality. This is legalism. Legalism refers to an emphasis on man-made rules and prohibitions as a requirement of spirituality. 
  
    Christendom has a rich legacy of legalism, and American  fundamentalism is no exception. Its  prohibition of alcohol, watching secular movies, playing cards, wearing make-up,  listening to secular music, dancing, etc. has done incalculable harm to  Christians and damage to Jesus’ reputation. 
    The logic of legalism is protection against sin: “If X is  sinful, it is spiritual to have a rule against activities that might tempt  you/others to do X.” Legalism says: “If  drunkenness is sinful, then it is spiritual to prohibit going places where  people get drunk.” Legalism says: “If  sexual immorality is sinful, then it is spiritual to prohibit women from dressing  in ways that might tempt men to lust sexually.”
  
  What’s wrong with legalism?  God never prescribed these rules, so who are we to make rules He hasn’t  made, or to say He made them when He didn’t?  Legalism distorts Christianity and prevents spiritual maturity in  several ways:
  
    It needlessly alienates non-Christians. It misrepresents God as a Cosmic Killjoy  instead of the Giver of Abundant Life.  It implies that we have to clean ourselves up morally before we can come  to Christ, instead of coming to Him as we are and allowing Him to change us  from the inside out. It creates ghettoes  of finger-pointers instead of people like Jesus, who never compromised morally,  but loved lost people and became known as “the friend of sinners.”
    It defines spiritual maturity negatively (“What I don’t/can’t  do”) instead of positively (“How I love and serve others”). It focuses people on impersonal rule-keeping  instead of on how to help people meet Christ and grow in Him. With a love-focus, I have the freedom to thankfully  enjoy God’s good gifts within His ethical absolutes, but I am willing to not  use these freedoms out of love to help people (1Cor.8-10). I am also able to not use these freedoms when  the Holy Spirit shows me that I am not presently able to handle them (e.g.,  former alcoholics abstaining from alcohol) without making them rules that  everybody has to obey.
  
Conclusion
  Paul summarizes his critique of these three religious practices  in 2:23 (read). What an insightful  critique! They look outwardly impressive,  but they are impotent to fix the real problem – our self-centeredness. You can be deeply into any/all of these without  loving anyone! In fact, they tend to  promote self-righteous pride, which is the antithesis of true spirituality!
  Biblical Christianity not only defines spiritual maturity  differently (growing in love vs. diligence in these religious practices); it  also prescribes a totally different way to move toward spiritual maturity. This is what Paul explains in chapters 3,4 (NEXT  SEVERAL WEEKS).
