Colossians 2:16-19 So don’t let anyone judge you about eating or drinking or about a festival, a new moon observance, or sabbaths. These religious practices are only a shadow of what was coming—the body that cast the shadow is Christ. Don’t let anyone who wants to practice harsh self-denial and worship angels rob you of the prize. They go into detail about what they have seen in visions and have become unjustifiably arrogant by their selfish way of thinking. They don’t stay connected to the head. The head nourishes and supports the whole body through the joints and ligaments, so the body grows with a growth that is from God.
Paul is wanting to be clear of the point he is making: stay grounded in Christ and firm in your faith. He wants to make sure that when the time comes people make fun of ceremonies you or I do or do not participate in that we will stand firm in our belief in Christ. Several of his letters seem to address similar situations. Everything we do should reflect Christ, not cast a shadow over the message.
There will be people we encounter who say we have to do certain rituals, or act a certain way to worship Christ. Paul says the people will even go into detail and become arrogant that they have had certain experiences and others have not. We are all on the same playing field because of Jesus Christ. This means that Christ is not looking for specific acts of worship. Although He is looking for us loving each other and showing love toward others to prove we are His disciples. Christ is simply asking us to follow Him and Him alone. He is not looking for anything we can use to justify our faith, He just wants our faith and love.
It is easy to say that other people are the ones who need to watch their arrogance; but this applies to us also. Our lives are meant to glorify Jesus Christ in all we say, do, even think. We stand on a higher ground, not because we want to be better than anyone else; but so we can be sure to be close to Christ in all we do.
