The supersession you're describing is a Pauline reading of Matthew 5:17.
“Do not think that I have come to abolish (καταλῦσαι / ܕ݁ܶܐܬ݂ܺܝܬ݂) the Law or the Prophets. I have not come to abolish them but to fulfill (πληρῶσαι / ܡܠܐ).”
I often hear Christians say, “Jesus fulfilled the covenant,” or something like it. So I looked into what that might actually mean. I’m not a Christian theologian, but I am a Pharisee, a Rabbi, and a Levantine Jew. That places me squarely within the audience Jesus was addressing when he used this phrase in the Sermon on the Mount.
I read his words as they would have been heard by a biblically literate Levantine Jew, perhaps even a Pharisee, given how often he speaks favorably of them. Josephus (Antiquities 13.10.6) tells us the common people favored the Pharisees. His audience would have been fluent in Scripture, halakha, and the layered linguistic world of the Second Temple period.
Language does not stand alone. The Greek of the New Testament is shaped by the Septuagint, the Greek translation of the Tanakh. In it, πληρόω frequently translates the Hebrew מלא (malé): to fill, to complete, to enact.
This becomes even clearer in the Peshitta, the early Aramaic version of the Gospels, which uses ܡܠܐ (malé), a direct cognate of מלא. In Biblical Hebrew, malé is rich. It can be literal ("the land was filled with violence"), legal (מִלּוּי יָדַיִם, "filling the hands" in priestly ordination), or poetic ("the earth is full of His glory"). It signals enactment, obligation, sacred duty. It does not suggest repeal.
Πληρόω maps to מלא over 70 times in the Septuagint. It means to carry out, to bring to full measure, not to end something.
Equally misunderstood is καταλύω, usually rendered "abolish." But in the Septuagint, it overwhelmingly translates the Hebrew לין (loun): to lodge, to pause, to dwell temporarily. Not to destroy. Not to override.
The Aramaic strengthens this reading. In the Peshitta, "abolish" is ܕ݁ܶܐܫܪܶܐ (deʾeshre), from ܫܪܐ (sharāʾ), meaning to loosen, to dwell, to begin. It evokes settling in, not dismantling.
This is not a statement of rupture. It is a halakhic ruling. Enactment, not expiration.
If we remap this into Hebraic idiom, it might read:
אַל תַּחְשְׁבוּ כִּי בָאתִי לָלוּן אֶת־הַתּוֹרָה אוֹ אֶת־הַנְּבִיאִים; לֹא בָאתִי לָלוּן כִּי אִם לְמַלֵּא
“Don’t suppose I have come to lodge over or complain about the Tora or the Prophets. I have come to bring them to full measure.”
This is not the voice of someone setting the Tora aside. It is the voice of someone affirming its authority, taking up its burden, and committing to its realization.
“Until heaven and earth pass away, not one iota or one keraia will pass from the Law until all is accomplished. Whoever loosens the least of these commandments will be least in the Kingdom. Unless your righteousness exceeds that of the scribes and Pharisees, you will not enter.” - Matthew 5:18–20
If he were announcing the expiration of the Tora, this would be a strange way to do it. He affirms the commandments. He affirms halakhic rigor. He even affirms the Pharisaic tradition, though he critiques its hypocrisy:
“The scribes and Pharisees sit in the seat of Moses. So whatever they tell you, do it. But do not imitate their actions. They speak, but do not act.” - Matthew 23:2–3
This is not the language of rejection of the Tora/Law. This is someone teaching from within the tradition, not against it.
Paul, in contrast, writes:
Χριστὸς γὰρ τέλος νόμου εἰς δικαιοσύνην
“Christ is the telos of the Tora/Law (Nomos) for righteousness.” - Romans 10:4
Telos can mean "end," but also goal, purpose, culmination. Just like πληρόω, it does not mean annulment. It means consummation.
Jesus says he came to fulfill the Tora, not abolish it. Paul says Christ is the telos of the Tora/Law (nomos). They might seem aligned. But Jesus speaks halakhically. Paul reframes it teleologically.
That is the shift.
