Ceremonies identified Israel as a nation that was in the world but separate from all the other nations. It played a part in driving the Gentiles up the wall and building barriers between them.
What makes the spiritual family that God is drawing us into separate and distinct from the world? God makes it clear: It is the way we live, not ceremonies or rituals! Jesus said, "By this shall all men know that you are My disciples, if you love one another" (John 13:53).
God insured that the ceremonies could not be performed. He allowed the Temple and the altar to be destroyed, and scattered the Levites all over the world. Those three things were necessary for making sacrifices. In order to get the focus away from the nation of Israel and the Old Covenant, God made sure that they could not make those sacrifices. (1) They had to be made at the Temple. (2) They had to be made on one altar. And (3) it had to be done by the Levites, and, specifically, the family of Aaron.
God got that out of the way because He wants people to focus on the way His children live! And His children live according to His law. If you do away with His law, you cannot live according to His law. You cannot show the characteristics of God unless you know the way that He lives, and He lives according to His law, which describes Him.
Though God no longer requires ceremonies, this in no way means that the spiritual intent of those ceremonies is done away. Though we are no longer required to cut an animal's throat, bleed its blood out, and burn it on an altar—the intent, the stretching out of those principles, still applies.
Thus, Jesus said in Matthew 18:9, "If your eye offend you, pluck it out." Jesus requires sacrifices so that we do not sin. Paul also said, "Put to death therefore your members which are on earth" (Colossians 3:5). He restates this in Romans 12:1 and Ephesians 5:2.
The principle of sacrifice remains. This is why Jesus could say that not one jot or tittle of that law would pass until all is fulfilled (Matthew 5:18). In the book of Galatians, the laws of God are hardly even in question except as they pertain to justification. Those laws that define sin, which guide us in the way of God, are just as binding as they ever have been, and they will remain so because God is using them to prepare us to live at one with Him and His Family.
