Does 2 Nephi 25 echo Paul?

The parallel is striking. Paul says he is dead to the law. Nephi says the law is dead to his people. Both connect that death with life in Christ, so I’d compare how each uses the idea before deciding what it tells us about authorship.

You identify the shared pattern and a real difference in wording. That makes the comparison more precise.

No. Both passages are scripture, so there cannot be any anachronism.

Your belief in scripture does not answer the historical comparison. First identify the overlap, then explain why it does or does not support the proposed conclusion.

They give the law a similar purpose. Paul says his audience is no longer under the guardian. Nephi says his people still keep the law until its fulfillment, even though they already have faith in Christ.

You show the shared idea and how it works on opposite sides of Christ’s coming. A modern writer could still adapt Paul to a different setting.

They both tell their readers they can stop keeping the law of Moses immediately.

Check 2 Nephi 25:24–25. Nephi says his people keep the law because God commanded it, and that they will do so until it is fulfilled.

The parallel matters. If a modern writer adapted Paul, both the wording and the argument could come from Galatians. If the book translates an earlier teaching, the biblical language could belong to the English rendering. What feature would help us tell those explanations apart?

You name two explanations for the same evidence and ask for a test that could distinguish them.

He shows that the Book of Mormon cannot be ancient because it teaches grace.

The essay’s proposed clue is the parallel between specific passages about the law and life in Christ, not merely the general teaching that salvation involves grace.
