The weekly Sabbath was never ceremonial. It was to commemorate the creation of the universe and was for all mankind. This is in Genesis. There were two more ceremonial Sabbaths that were done away with.
"was historically changed to honor Christ’s resurrection "
It was indeed historically changed (by man) but never Biblically changed by God. Jesus Himself said "If you love Me, keep my Commandments". Most have been taught what you have but the Bible truth remains for those who read it for themselves. Will Jesus ask you if you loved Him why didn't you follow His Commandments?
So; what ARE Jesus' "commandments"?
