ἀνακεφαλαιόομαι

From the study of Romans 13:9

Range of meaning

To sum up, to total, to recapitulate. It is built from kephalaion, “the main point, the sum, the heading” (the word for a total sum of money or the chief point of an argument), plus ana-, “up/again.” So it means to bring many items together under one heading or total.

Against the English

“Summed up” (BSB, ESV, NIV, WEB, NASB) and KJV's “briefly comprehended” both fit well. The thing to avoid is reading “summed up” as “replaced” or “made unnecessary.” A total does not abolish the figures it adds up.

How it drifted

The Latin Vulgate renders it instauratur (“is renewed/restored”), the same verb it uses in Ephesians 1:10. Later Christian thought, from Irenaeus on, built a large theology of “recapitulation” on Ephesians 1:10. That rich meaning should not be read back into this ordinary rhetorical use in Romans 13:9.

Used elsewhere in the period

Rhetoricians used the noun anakephalaiōsis for the summary at the end of a speech (Quintilian, Institutes 6.1.1, gives the Greek term for the “repetition and gathering together of the facts”). The verb occurs in the New Testament only here and in Ephesians 1:10 (“to gather up all things in Christ”). It is not used in the Greek Old Testament.

From the study of Ephesians 1:10

Range of meaning

It comes from kephalaion, "the main point, the sum, the total" (as in a column of figures or the heads of an argument), plus ana-, "again, up". Meanings: to sum up, to restate in summary, to gather into one main heading. In rhetoric it is the recap at the end of a speech, where the separate points are drawn together. It is not formed directly from kephalē ("head"), though Greek ears could hear the echo.

Against the English

KJV "gather together in one"; YLT "bring into one"; WEB "sum up"; BSB "bring… together"; ESV "unite"; NIV "bring unity to… under Christ"; NLT "bring everything together under the authority of Christ"; NASB "summing up". "Sum up" keeps the root picture. "Unite" or "bring unity" catches the result but loses the idea of a single heading or total. Renderings with "under Christ" or "under the authority of" bring in the theme of headship and rule from 1:22. That is defensible from context but is an interpretation, not the word itself.

Used elsewhere in the period

Elsewhere in the NT only in Rom 13:9, where the commandments are "summed up" in "love your neighbour as yourself": many items, one heading. Rhetorical writers use the noun anakephalaiōsis for the summary at the end of a speech (Quintilian, Inst. 6.1.1, notes the Greek term). The word does not occur in the canonical LXX. Irenaeus (late 2nd century, Against Heresies 3.16.6; 5.20.2) built his doctrine of "recapitulation" on this verse: Christ re-runs and restores humanity's story. That is a later development, though it grows from this word.
