There are at least two passages in the letters to the churches that show that Jesus removed the old law by his death. They are Ephesians 2:11-18, especially verse 15 which tells us that "the law of commandments contained in ordinances” was abolished by Jesus, and Colossians 2:8-17, particularly in verse 14 where Paul writes that Christ has taken “the handwriting of ordinances” and blotted it out by “nailing it to his cross”. The law of commandments and handwriting of ordinances are clearly phrases that refer to the law of Moses. Paul says in Romans 7:6 that we are delivered from the law, and, according to 8:2, that “the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.” He also maintains that to those who are without the law he is as without the law (the law of Moses), but makes it clear that he is still under the law of Christ in First Corinthians 9:21. Paul also tells the Romans in chapter 10 verse 4 that, “Christ is the end of the law for righteousness to every one that believeth." And in Galatians 3:24-25 "Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. {25} But after that faith is come, we are no longer under a schoolmaster."
It would seem that these scriptures should be enough, but some will not be satisfied. Many say that we don’t have to keep all of the sacrifices, but that we must keep the 10 commandments. Others want to hold on to tithing, or some other part of the law of Moses and demand that we follow it today. That is nothing new. In the first century there were Jews who wanted to force circumcision or some other parts of the law on the Gentile Christians. Paul deals with this in Galatians 5:1-4 "Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage. {2} Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing. {3} For I testify again to every man that is circumcised, that he is a debtor to do the whole law. {4} Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace." You have to make a choice between circumcision and grace, between Moses and Christ. You can’t have both. The apostles met in Jerusalem with the elders of the church to discuss this very thing. Are we under the law of Moses or Christ or both? Does one have to obey Moses’ law and be circumcised to be pleasing to God? In Acts 15 part of this meeting containing the conclusion of the matter is recorded for us. Verse 5 says, "But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses." Peter responded by asking, "Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?", in verse 10.
This matter was settled nearly 2000 years ago, or should have been, and yet today we still have many teaching us that we must keep the Sabbath, tithe, keep the ten commandments, or any number of other things that were done away with by Christ and declared to be a tempting of God by one of his closest apostles. If you want to continue to keep these things you lose any benefit Christ has to offer, and you are bound to keep every bit of that law that none but Christ ever could.
