This verse encourages us to don't let those people throw us off course. Our promise and substance is found in Jesus alone.
Colossians 2: 16 -17
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.
