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. Do not let anyone who delights in false humility and the worship of angels disqualify you. Such a person also goes into great detail about what they have seen; they are puffed up with idle notions by their unspiritual mind. They have lost connection with the head, from whom the whole body, supported and held together by its ligaments and sinews, grows as God causes it to grow.
There is a deep, very profound truth contained in these lines; namely, it is our relationship with Jesus that matters. It is not what we eat or drink; it is not how we worship; it is not how we observe festivals. No, it is all about putting Jesus first, and front and centre. Jesus is the head. All things hold together in him, and through him growth from God comes.
So, if folk in your church want to do things differently, don't worry much about that. Instead, why not ask yourself a different question to the usual one. Why not ask where you might find Christ in it. If Christ is being put first what's the problem?
Lord Jesus, I long to hold fast to you. Please send your Holy Spirit to keep me close to you. Amen.
