Only the OT ceremonies that are specifically mentioned as nullified by the New Covenant are to be treated with such disregard, and NONE of them deserve the contempt you have placed upon this topic.
Why is it that we don't sacrifice animals to God? Would it displeased Him? No.
We don't sacrifice animals for the sake of our own consciences, that we may be tempted to put faith in a redundant ritual, rather than in Christ. Sacrifices were actually done away with in Christ, as He is the complete and perfect sacrifice. If you are in Christ, you have no sin, and therefore no need of additional sacrifice for atonement.
What other command is as redundant as sacrifice of animals to cover sins? None.
Are grain offerings banned by the NT? Are tithes banned by the NT? Is not cutting the edges of my beard banned by the NT? Is leaving the corners of my field unharvested banned by the NT?
No Law is banned by the New Covenant. Only those who have placed their faith back in laws, rather than in the Blood of Christ, are judged as under the Law. The precepts of the Law are always good, and it's commands are always good.
Playing instruments was never an OT command for the people of God, but it was always commended as good and pleasing to God as praise. Has God changed?
For those who seek to be given rules, beyond what is stated in Scripture, are under law just as much or even more than any Hebrew. Who of you can live up to the standard of Christ? And yet you place yourselves under laws even He was not subject to. Distracted by "holy" culture!!! The Pharesees and Plato would applaud.
