Burning animals might have been a component of the OC and it might have even been done at times on the Sabbath but that does not mean it's part of Sabbath keeping.
Your ignorance of the law is not an excuse for noncompliance to it, for
the law is not of faith, but "the man who does them shall live by them." (Galatians 3:12). Here is what the law states as requisite to keep the sabbath holy:
Numbers 28
9 `And on the Sabbath day two lambs in their first year, without blemish, and two-tenths of an ephah of fine flour as a grain offering, mixed with oil, with its drink offering--
10 `this is the burnt offering for every Sabbath, besides the regular burnt offering with its drink offering.
By saying the Ten Commandments are done away with you trample over the grace of God. You say you have no need for God's grace because you have no need for God's Law.
By
saying that you keep the Ten Commandments, in contradiction to God's conclusion of your performance according to Jeremiah 31:32 and Romans 11:32, and then violating the decree in the Ten Commandments to keep the sabbath holy, you violate the entire covenant while you bear false witness and consider God a liar.
You heal the sick and cast out demons in the name of Jesus but you are those who practice lawlessness and are not known by Jesus.
I have to break the bad news to you; someone does.
You're practicing lawlessness. There isn't anyone alive who isn't practicing lawlessness according to God's conclusion, and the only difference between those that Jesus never knew and those who do the will of God is who Jesus remembers the sins of. The redeemed of God have His promise "
Their sins and their lawless deeds I will remember no more", and those reliant on their feigned performance will have their iniquity remembered outside of God's redemption.
The faith of Jesus magnified and restored honor to the Law and taught us how to keep the Ten Commandments in light of love. These are the two foundational aspects of the NC, keeping the commandments of God and having the faith of Jesus.
Jesus didn't teach you how to commit adultery with your former husband He redeemed us from. And no one told you to discard the commandments of God and replace them with the covenant Jesus Christ delivered us from and took away by His own Hand.
They will fullfill the prophecy of Isaiah who said, "People will worship God with their lips but their heart will be far from Him". This was said in light of changing the Ten Commandments and replacing them with the commandments of men.
That's what you're doing when you discard God's holy law while professing to keep it, and feigning ignorance of the law when you fail to comply with the burnt offerings.
I think that's enough - God told us to turn away from those professing to have a form of Godliness while concluding that God is a liar.
