Christ redeems from the curse of the Law; AD 70 displays the covenant curses falling on the old order that rejected Him.
The Law carries blessing for loyalty and curse for covenant breach (Deuteronomy 27–28). Paul states the problem without softening: “Cursed is everyone who does not continue in all things written in the book of the Law, to do them” (Galatians 3:10). The Law’s prosecutorial power is real under the old administration.
Christ redeems those under the Law by becoming a curse for them, as it is written, “Cursed is everyone who is hanged on a tree” (Galatians 3:13). The cross answers the curse for those who are in Him. Justification is not achieved by law-keeping; it is received by faith.
For the believer, the curse as condemning covenant standing is exhausted in Christ. There is now no condemnation for those in Him (Romans 8:1). The Law’s power to prosecute unto death is broken because its sentence was borne by the Son.
For the old order that clung to the Law while rejecting the Messiah, the Deuteronomic pattern of national judgment still spoke. Jesus announces desolation on Jerusalem, days of vengeance, and the fall of the house (Matthew 23–24; Luke 21). AD 70 is that historical climax — covenant judgment on the administration that would not repent.
Redeemed from the curse in Christ; the old house bears the historical curse it chose.
These are not contradictions. They are two sides of the same transition.
If the cross alone is named and the fall of the Temple is treated as irrelevant, the public end of the curse-bearing system is muted. Paul can say the sting of death is sin and the power of sin is the Law (1 Corinthians 15:56). When the Law-system as covenant administration ends, the prosecutor loses the public court in which that administration operated.
You are not under the curse as a covenant status if you are in Christ. You are not summoned back under Moses to complete what the cross finished. The blessing of Abraham comes to the nations in Christ Jesus, that we might receive the promise of the Spirit through faith (Galatians 3:14).
The point-by-point historical witness — eagle, walls, famine, the woman of Bethezuba, unburied dead, and the return toward Egypt — is set out in the study Deuteronomy 28 and the Judgment of Jerusalem.
