Short answer: no, Christians are not under the Mosaic Law — but that doesn't mean the Old Testament is just a vibe check you can ignore. is pretty clear that we've moved into a situation, and the rules of the old one don't apply the same way anymore. That said, there's a lot going on here, so let's break it down fr.
The Old System Was Always Temporary {v:Galatians 3:23-25}
The Torah — the 613 commandments given to Moses at Sinai — was a covenant between God and the nation of Israel. It was always designed for a specific people, in a specific time, for a specific purpose.
Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. So then, the law was our guardian until Christ came, in order that we might be justified by faith. But now that faith has come, we are no longer under a guardian.
That word "guardian" (some translations say "tutor" or "schoolmaster") was a Greek term for the servant who walked kids to school. His job was important — but once you graduate, you don't keep reporting to him every morning. The Law was doing a real job. That job is done.
Jesus Didn't Cancel It — He Fulfilled It {v:Matthew 5:17}
This part is key, because people lowkey misread this. Jesus didn't swipe left on the Old Testament.
🔥 "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them."
"Fulfill" means he completed what the law was pointing toward. Every sacrifice? Pointed to him. Every purity ritual? Pointed to him. The whole system was a massive preview trailer, and Christ was the actual movie. Once the movie drops, you don't need the trailer anymore.
So Which Rules Still Apply?
This is where it gets real, and theologians have thought about it a lot. The classic evangelical framework (going back to guys like John Calvin) breaks the Mosaic law into three categories:
Ceremonial law — sacrifices, dietary restrictions, purity rituals, the priesthood. These were fulfilled in Christ. That's why you can eat shrimp without sinning. That's why Peter got the vision in Acts 10 telling him the food laws were lifted. These pointed to Jesus; Jesus showed up; they're done.
Civil/judicial law — laws that governed Israel as a theocratic nation-state (land boundaries, property laws, penalties for crimes). Those applied to Israel specifically as a political entity. Christians today aren't ancient Israel, so we don't run our governments by them — though the principles of justice behind them still matter.
Moral law — don't murder, don't steal, don't lie, honor your parents, no other gods. These show up in the New Covenant too, because they reflect God's unchanging character. Paul quotes them in his letters all the time. James does too. Jesus himself cranked them UP in the Sermon on the Mount (not just "don't murder" — don't even hate).
The Honest Caveat
Not every evangelical draws those three lines the same way. Some scholars think the tripartite division is too neat and doesn't fully map onto how the Torah was written. Theonomists think more of the civil law should apply today. New Covenant theologians draw the lines differently again. There's genuine debate here.
What basically everyone agrees on: the Mosaic covenant as a whole system is not the operating system for the Christian life. Paul says in Romans 6:14 that we are "not under law but under grace." Hebrews 8 straight up calls the old covenant "obsolete." That's not us being dismissive — that's what the New Testament says.
What We're Actually Under {v:Romans 8:3-4}
The goal was never just rule-following — it was transformation. Paul says the law couldn't do what God really wanted because our flesh kept fumbling the ball. So God did it a different way:
For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.
The Spirit writes the moral law on your heart (Jeremiah 31, quoted in Hebrews 8). You're not checking a rulebook — you're being changed from the inside. That's the upgrade. That's the New Covenant.
So no, you don't need to stress about the mixed fabrics in your hoodie. But "love God, love people" — that one's not going anywhere.
