Colossians 2:16-17 Part 1 of 2

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 the things that were to come; the reality, however, is found in Christ. 

Therefore do not let anyone judge you 
Romans 14:3-4  The one who eats everything must not treat with contempt the one who does not, and the one who does not eat everything must not judge the one who does, for God has accepted them. Who are you to judge someone else's servant? To their own master, servants stand or fall. And they will stand, for the Lord is able to make them stand.

by what you eat or drink 
Mark 7:18-19  "Are you so dull?" he asked. "Don't you see that nothing that enters a person from the outside can defile them? For it doesn't go into their heart but into their stomach, and then out of the body." (In saying this, Jesus declared all foods clean.)
Romans 14:17  For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, ...

or with regard to a religious festival 
Leviticus 23:2  "Speak to the Israelites and say to them: 'These are my appointed festivals, the appointed festivals of the LORD, which you are to proclaim as sacred assemblies.' "
Romans 14:5  One person considers one day more sacred than another; another considers every day alike. Each of them should be fully convinced in their own mind.

a New Moon celebration 
1 Chronicles 23:30-31  They [the Levites] were also to stand every morning to thank and praise the LORD. They were to do the same in the evening and whenever burnt offerings were presented to the LORD on the Sabbaths, at the New Moon feasts and at the appointed festivals. They were to serve before the LORD regularly in the proper number and in the way prescribed for them.

or a Sabbath day 
Mark 2:27-28  Then he said to them, "The Sabbath was made for man, not man for the Sabbath. So the Son of Man is Lord even of the Sabbath." 
Galatians 4:9-10  But now that you know God--or rather are known by God--how is it that you are turning back to those weak and miserable forces? Do you wish to be enslaved by them all over again? You are observing special days and months and seasons and years!
