Paul has just told a congregation being pressed toward circumcision that they were called ἐπʼ ἐλευθερίᾳ — for freedom — and then immediately forbidden them to make that freedom a staging-ground for the flesh, commanding instead that they slave for one another through love (v. 13). Verse 14 supplies the ground (γάρ) for that startling command: the whole law stands filled up in one word, Lev 19:18.

Three things carry the weight.

1. ὁ πᾶς νόμος — articular πᾶς, “the law taken as a whole.” Paul is not selecting a summary from among the commandments; he is making a claim about the law’s totality. Two verses earlier he warned that the man who accepts circumcision is a debtor ὅλον τὸν νόμον ποιῆσαι (5:3). The same totality that cannot be done has, he now says, already been filled up.

2. πεπλήρωται — perfect passive, not the active a summary-statement would require. Something has been done to the law, its result stands, and the agent is not named. Paul does not write “you fulfill the law by loving,” which is what most paraphrases produce.

3. The citation is Lev 19:18 LXX word for word, and it stands unmarked by any citation formula — introduced only by the resumptive article ἐν τῷ, as if the verse were being pointed at rather than quoted.

The live question, which the apparatus does not resolve, is whether v. 14 is a summary (love does everything the law asked), a claim about eschatological accomplishment (the law’s demand has been met in Christ and now takes effect in the Spirit-community), or a barbed concession (you want the whole law? here it is, one line, and you are biting each other — v. 15).

The construction is article + πᾶς + noun, which classical grammar treats as holistic (“the whole of X”) as against anarthrous πᾶς + singular, which is distributive (“every X”) — the rule already fixed for πᾶν γόνυ at Phil 2:10 and revisited at Phil 1:3.

But the word order here is unusual. Paul’s normal phrasing for “the whole law” is ὅλος ὁ νόμος (as at 5:3, ὅλον τὸν νόμον), and that is what a scribe would expect. The order ὁ πᾶς νόμος — article, πᾶς, noun — is rare in the NT (cf. ὁ πᾶς χρόνος, Acts 20:18; τὸν πάντα χρόνον). BDF treats the position as intensive, and the effect is something like “the law, the entire thing of it.”

Why Paul switched from ὅλος to πᾶς between v. 3 and v. 14 is a real question. The most economical account is that he wanted the totality-word in the emphatic slot before the noun so that the contrast with ἑνὶ λόγῳ — whole against one — lands audibly. English cannot reproduce the fronting, so “the whole law” is retained and the emphasis is recorded here.

What the phrase does not mean: “every law,” “all laws,” or “the law in all its parts, item by item.” The articular construction closes off the distributive reading, and with it the reading that Paul is claiming each individual commandment is separately discharged by love.

Proposed — pending reviewRichard N. Longenecker, Galatians, Word Biblical Commentary 41 (Dallas: Word, 1990)

πληρόω is already fixed in this corpus as fill up / make full, with the vessel-image treated as live rather than dead (Phil 1:11; 2:2; 4:18-19). That decision has teeth here, because almost every smooth English rendering of this verse converts the metaphor into an abstraction — “is summed up,” “is complete,” “finds its full expression.”

Three features of the form must survive:

• Perfect. A completed act whose result stands at the time of writing. Not “is being fulfilled” (present), not “was fulfilled” (aorist). The law’s filling-up is a settled state of affairs Paul can appeal to as a premise.
• Passive. The agent is unexpressed. English must not supply one. “You fulfill the whole law by loving your neighbor” is an active-voice sentence Paul did not write, and it relocates the accomplishment from an unnamed agent to the addressees.
• Singular. The subject is ὁ πᾶς νόμος, not the commandments plural.

The lexical range of πληρόω runs from filling a physical container (Matt 13:48) through completing a period of time (Mark 1:15) to bringing a prophecy to its intended realization (Matt 1:22 and throughout). At Rom 8:4 Paul uses the cognate passive πληρωθῇ of the law’s δικαίωμα being filled up ἐν ἡμῖν — in us who walk according to Spirit and not flesh. That is the closest Pauline parallel and it points the same direction as Gal 5:16-18, three verses on.

Note what Paul avoids. He does not use ποιέω (“do”), which is his verb for law-observance at 5:3 (ποιῆσαι) and 3:10, 12, nor τελέω (Rom 2:27; Jas 2:8), nor ἀναπληρόω (Gal 6:2, of Christ’s law). The switch of verb between 5:3 and 5:14 is deliberate: what the circumcised man is obliged to do is not what love has filled up.

Proposed — pending reviewJ. Louis Martyn, Galatians: A New Translation with Introduction and Commentary, Anchor Bible 33A (New York: Doubleday, 1997)

λόγος here is a single utterance — a saying, a sentence — not the commercial account fixed for Phil 4:15, 17, and not the absolute ὁ λόγος (“the word,” the gospel proclamation) fixed for Phil 1:14. The dative is anarthrous and qualitative, and ἑνί is doing real work: one, over against the manifold commandments a proselyte would be taking on.

The force of ἐν is genuinely open between sphere (“within the compass of one word”) and means (“by means of one word”). English “in” admits both and is retained; “by” would tip instrumental and would strengthen the summary reading. Compare the corpus policy on ἐν + dative with abstract nouns after verbs of growth (Phil 1:9), where the same ambiguity was preserved rather than resolved.

A rabbinic and Hellenistic-Jewish background is worth naming without over-pressing it: the practice of reducing Torah to a single principle is attested (the Hillel saying in b. Šabb. 31a; Philo’s twofold summary of the Decalogue under piety toward God and justice toward men). Paul’s move is recognizable within that world. What is not recognizable within it is his making the one word the horizontal commandment alone, with no companion clause about loving God — which is the distinctive of Gal 5:14 and Rom 13:9 over against Mark 12:29-31.

ἐν τῷ repeats the preposition and adds the article, resuming ἑνὶ λόγῳ: “in the [one word], namely.” The article is anaphoric and functions as a quotation-marker — Greek has no quotation marks, and the neuter/masculine article before a cited phrase is one of the ways the language flags that what follows is being pointed at rather than asserted afresh (cf. Rom 13:9, ἐν τῷ λόγῳ τούτῳ; Eph 4:9, τὸ δὲ ἀνέβη).

Two things follow for the rendering:

1. The article must not be deleted as redundant. It is the seam between Paul’s sentence and Leviticus, and it is what makes the citation a citation.
2. There is no citation formula — no γέγραπται, no λέγει ἡ γραφή, both of which Paul uses freely in Galatians (3:10, 13; 4:22, 30). He simply names the word and quotes it. The absence is data: the sentence is presented not as a proof-text adduced but as a text already known and agreed.

The literal tier keeps the bracketed supplement “in the [one]”; smooth registers may use “in this,” which performs the same anaphoric-plus-quotative function in English.

Paul’s words are Lev 19:18 LXX exactly: ἀγαπήσεις τὸν πλησίον σου ὡς σεαυτόν. The LXX renders MT וְאָ֥הַבְתָּ֥ לְרֵעֲךָ֖ כָּמ֑וֹךָ.

One feature of the Hebrew is worth naming because it is invisible in Greek and in English. MT has אָהַב construed with the preposition לְ — literally “you shall love to your neighbor,” an unusual construction (the verb normally takes a direct object). Some have argued the lamed makes the sense “be of use to, act lovingly toward,” which would push the command toward conduct rather than affection. The LXX flattens it with a plain accusative τὸν πλησίον, and Paul inherits the flattening. Since Paul is working from the Greek, the Greek governs the rendering here; the Hebrew construction is recorded and not imported.

The verse’s context in Leviticus matters for the πλησίον question below: Lev 19:18 stands in a paragraph about dealings within Israel (v. 17, “your brother … your fellow-countryman”), and Lev 19:34 extends the same love-command to the resident alien (τὸν προσήλυτον).

The same citation is used at Rom 13:9, Matt 19:19, 22:39, Mark 12:31, Luke 10:27, and Jas 2:8 — a remarkably uniform textual form across all of them, which suggests a fixed catechetical wording rather than independent quotation from a scroll.

The form is a future indicative, not an imperative. This is the standard LXX rendering of the Hebrew imperfect used for apodictic law (the Decalogue throughout: οὐ φονεύσεις, οὐ μοιχεύσεις, Exod 20:13-15 LXX), and Koine took it over as a legitimate way of expressing command — BDF classes it as a Semitizing imperatival future.

English “you shall love” preserves both the form and the legal register, and it is retained. Two alternatives are rejected:

• “Love your neighbor” — converts the future to an imperative, erasing the Decalogue-shaped form that marks this as cited legislation.
• “You will love your neighbor” — reads in modern English as a prediction.

The verb is ἀγαπάω, whose noun ἀγάπη is fixed in this corpus as love with no over-specification in the main text. That policy holds here: the frequently repeated claim that ἀγάπη denotes a distinctively volitional or self-giving love as against φιλέω is not sustainable on first-century lexical evidence (the LXX uses ἀγαπάω of Amnon’s desire for Tamar, 2 Kgdms 13:1, 4, 15), and the content of the love comes from the context — vv. 13 (δουλεύετε ἀλλήλοις) and 15 (δάκνετε καὶ κατεσθίετε) — not from the lexeme.

The second-person singular is worth noting: Paul has been addressing a plural congregation throughout (ἐκλήθητε, δουλεύετε, βλέπετε), and the citation drops into the singular because Leviticus does. He leaves the number as it stands rather than adapting it, which is further evidence that the words are being quoted rather than composed.

πλησίον is an adverb (“near, close by”) used substantivally with the article — literally “the [one] near.” The LXX uses it as the standard equivalent of Hebrew רֵעַ, “fellow, associate, the other party in a transaction.”

The scope question is old and it is a §5 flashpoint, so the positions are set out rather than adjudicated by word choice. In Lev 19:18 the immediate frame is intra-Israelite (v. 17 pairs it with ἀδελφός and the sons of your people), while v. 34 of the same chapter extends love to the προσήλυτος. In first-century Jewish usage the term’s boundary was actively debated — which is exactly the question the lawyer puts to Jesus at Luke 10:29, τίς ἐστίν μου πλησίον, and which the parable answers by relocating the question from who qualifies to who acts as one.

In Gal 5:14 the referent is almost certainly, in the first instance, the fellow member of the congregation. Paul has framed the paragraph with ἀλλήλοις (v. 13) and ἀλλήλους … ἀλλήλων (v. 15), and 6:10 will distinguish πάντες from οἱ οἰκεῖοι τῆς πίστεως. But he cites the Leviticus wording rather than writing ἀλλήλους here, and that choice keeps the wider scope in view.

The rendering neighbor is retained as the standard English equivalent. It is not ideal — modern English “neighbor” suggests residential proximity, whereas πλησίον/רֵעַ denotes the person one is dealing with — but the alternatives are worse: “fellow member” narrows to the congregation, “fellow human being” universalizes, and both write an answer to the contested question into the reading text.

ὡς + reflexive accusative supplies the measure of the loving. The construction is elliptical: no verb is expressed in the comparison, and the accusative σεαυτόν is governed by the ἀγαπήσεις carried over from the main clause — “as [you love] yourself.”

What the clause does and does not assert:

• It states a measure, not a second duty. Greek does not command self-love here; it assumes it as the given standard, in the way the Hebrew כָּמוֹךָ does. Reading the phrase as prescribing self-love before neighbor-love is a modern psychological gloss and has no support in the syntax.
• Whether the comparison is quantitative (“to the same degree as”) or modal (“in the same manner as”) is not decided by the Greek, and ὡς will bear either. The idiomatic English “as yourself” is equally undecided and is retained.

A minority construal takes כָּמוֹךָ / ὡς σεαυτόν adverbially with the whole clause — roughly “love your neighbor, who is like yourself,” i.e. one of your own kind. This has been argued from the Hebrew and would tie the command to the intra-Israelite frame of Lev 19:17.

The verse is textually stable in substance; the variation is at two minor points and neither affects the sense.

ἐν ἑνὶ λόγῳ. A few witnesses read ἐν ὑμῖν or omit ἑνί. The reading with ἑνί is supported across the early Alexandrian and Western witnesses and is required by the contrast with ὁ πᾶς νόμος; the omissions are simplifications.

ἐν τῷ. Some witnesses read ἐν τῷ λόγῳ (filling out the ellipsis), others expand to ἐν τούτῳ. Both are the kind of clarifying supplement scribes routinely add where an article stands alone before a citation, and both smooth a construction the critical text preserves in its terser form. NA28 prints the bare ἐν τῷ without brackets.

σεαυτόν / ἑαυτόν. The reflexive is spelled both ways in the manuscript tradition; ἑαυτόν for the second person is common Koine and carries no semantic weight.

γάρ is load-bearing and must be rendered (§10). It grounds the command of v. 13b — through love, slave for one another — and the grounding is what makes the paragraph coherent rather than paradoxical.

The shape of the movement:

• v. 13a You were called for freedom.
• v. 13b Not freedom as a staging-ground for the flesh; instead, δουλεύετε ἀλλήλοις — the very verb of slavery Paul has spent chapter 4 using of bondage under the law (4:8, 9, 25). The paradox is deliberate.
• v. 14 For the whole law stands filled up in one word.
• v. 15 But if you bite and devour one another — the counter-case, in animal language.
• v. 16 Now I say: walk by Spirit.

So v. 14 sits between an imperative it grounds and a warning it exposes. And it stands in tension — a productive one — with 5:3, where the man who receives circumcision becomes ὀφειλέτης ὅλον τὸν νόμον ποιῆσαι. The same totality that is an unpayable debt when undertaken is a filled vessel when received. Paul is not contradicting himself; he is distinguishing the law as a regime to be entered (ὑπὸ νόμον, 5:18; 4:4-5, 21) from the law as a demand already met, whose content the Spirit-walking community now embodies.

This also explains why Paul cites the horizontal commandment alone, without the love-of-God clause that accompanies it in the Synoptic double command (Mark 12:29-31). His problem at Philippi—no, at Galatia—is not defective piety toward God; it is a congregation biting each other while arguing about circumcision. The one word he selects is the one they are breaking.

Proposed — pending reviewHans Dieter Betz, Galatians: A Commentary on Paul's Letter to the Churches in Galatia, Hermeneia (Philadelphia: Fortress, 1979)

The patristic reading is fairly uniform on the point at issue and diverges from most modern paraphrase in an instructive way.

Chrysostom (Homilies on Galatians, ad loc.) takes the verse as Paul turning the agitators’ own demand back on them: if you are so eager for the law, here is the law entire, and it is being trampled by the very people demanding it. He reads the perfect as real — the law’s whole aim has been reached in love — and stresses that Paul deliberately says nothing about circumcision or food, because love is the sum and root from which the rest grows.

Jerome (Commentary on Galatians) presses the relation to 5:3: the man who takes on circumcision owes the whole law; the man who loves has the whole law. He is also alert to the ellipsis at ἐν τῷ and to the fact that Paul quotes without a formula.

Augustine, across his anti-Pelagian works, takes Gal 5:14 with Rom 5:5 and 13:10: the law is fulfilled by love, and the love by which it is fulfilled is itself poured out by the Spirit. That is not a lexical argument, but it is the earliest sustained attempt to hold the perfect passive and the imperatives of vv. 13, 16 together — and it is the reading that best explains why v. 14’s γάρ can ground a command.

Vulgate: omnis enim lex in uno sermone impletur: diliges proximum tuum sicut te ipsum. Note impletur — present passive, not perfect. Latin loses the standing-result force of πεπλήρωται, and much of the English tradition’s “is fulfilled” descends through that present tense. Per §11 the Latin is reception, not evidence; the Greek perfect governs.
