16 So don’t let anyone condemn you for what you eat or drink, or for not celebrating certain holy days or new moon ceremonies or Sabbaths. 17 For these rules are only shadows of the reality yet to come. And Christ himself is that reality. 18 Don’t let anyone condemn you by insisting on pious self-denial or the worship of angels, saying they have had visions about these things. Their sinful minds have made them proud, 19 and they are not connected to Christ, the head of the body. For he holds the whole body together with its joints and ligaments, and it grows as God nourishes it. (NLT)
Here Paul is talking about rules people make up for themselves and attempt to require others to follow and do them. They will often condemn you if you don’t do it their way. You can see the types of things Paul is talking about. Some people have made a religion out of what you can eat or drink. Others say Saturday is the Sabbath while others insist that only Sunday is the true Sabbath.
Another problem in the church then and in some circles even today is visions and particularly of angels and following those teachings as if they were the gospel. I’ve had visions and they only support what you see God is doing in your life. If they are some strange revelation which has you pounding out copper sheets and writing a new bible then as Paul says they are from sinful minds. They are either making up a vision about things which they have not really seen or seeing a lying vision. God will send visions which nourish the body.
Jesus is the head. Those connected to the head won’t condemn you or insist you follow some formula that feeds pious self-denial. Those being nourished by the Head will hear the truth and it is always freeing. If some teaching puts you in bondage, then it didn’t come from God. The truth always makes you free.
The true believer is part of the body of Christ and therefore works together under the authority of Jesus who is our head.
