STRONGS NT 2531: καθώς

καθώς (i. e. καθ' ὡς), a particle found occasionally in secular authors from Aristotle down for the Attic καθά and καθό, but emphatically censured by Phryn. and the Atticists; cf. Sturz, De dial. Maced. etc., p. 74ff; Lob. ad Phryn., p. 425f; (Winer's Grammar, 26 (25));

1. according as, just as, even as: in the first member of a comparison, Luke 6:31; 1 John 2:27; followed by οὕτως in the second member (cf. Winer's Grammar, § 53, 5), Luke 11:30; Luke 17:26; John 3:14; 2 Corinthians 1:5; 2 Corinthians 10:7; Colossians 3:13; 1 John 2:6; followed by καί also, John 15:9; John 17:18; John 20:21; 1 John 2:18; 1 John 4:17; 1 Corinthians 15:49; it is annexed to preceding words after the demonstrative οὕτως, Luke 24:24; with οὕτως unexpressed, Matthew 21:6; Matthew 28:6; Mark 16:7; Luke 1:2, 55, 70; Luke 11:1; John 1:23; John 5:23; Acts 10:47 (here L T Tr WH ὡς); ; Romans 1:13; Romans 15:7; 1 Corinthians 8:2; 1 Corinthians 10:6; 2 Corinthians 1:14; 2 Corinthians 9:3; 2 Corinthians 11:12; Ephesians 4:17, and often; καθώς διδάσκω, agreeably to my method of teaching, 1 Corinthians 4:17; καθώς γέγραπται, Matthew 26:24; Mark 9:13; Acts 7:42; Acts 15:15; Romans 1:17, and often in Paul; the apodosis lacking, and to be gathered from the context: καθώς παρεκάλεσα σε ... ἐν πίστει, namely, οὕτω καί νῦν παρακαλῶ, 1 Timothy 1:3, cf. Winers Grammar, 570 (530); (Buttmann, 386 (331)); ἤρξατο αἰτεῖσθαι (namely, οὕτω ποιεῖν αὐτοῖς), καθώς κτλ.. Mark 15:8 (Buttmann, § 151, 23 b.; cf. Winer's Grammar, 584 (543f)); in comparison by contrary we find the negligent use: ἀγαπῶμεν ἀλληλου, οὐ καθώς Κάϊν κτλ., 1 John 3:11f, cf. DeWette at the passage and Winer's Grammar, 623 (579); οὗτος ἐστιν ἄρτος ... οὐ καθώς etc., not such as they ate etc., John 6:58. with the verb εἰμί, equivalent to Latinqualis, such as, 1 John 3:2; in a parenthesis, 1 Thessalonians 2:13 (as it is in truth).

2. according as i. e. in proportion as, in the degree that: Mark 4:33; Acts 7:17 (cf. Meyer at the passage); ; 1 Corinthians 12:11, 18; 1 Peter 4:10.

3. since, seeing that, agreeably to the fact that (cf. Winer's Grammar, § 53, 8; 448 (417)): John 17:2; Romans 1:28 (yet here others regard καθώς as corresponsive rather than causal or explanatory); 1 Corinthians 1:6; 1 Corinthians 5:7; Ephesians 1:4; Philippians 1:7.

4. it is put for the simple ὡς, a. after verbs of speaking, in indirect discourse, Acts 15:14; it serves to add an epexegesis, 3 John 1:3 (to σου τῇ ἀλήθεια).

b. of time, when, after that (cf. Latinut): 2 Macc. 1:31; (Nehemiah 5:6); here many bring in Acts 7:17; but see 2 above.

STRONGS NT 2531a: καθώσπερκαθώσπερ (Tr καθώς περ), just as, exactly as: Hebrews 5:4 T Tr WH (also 2 Corinthians 3:18 WH marginal reading). (Himerius, Psellus, Tzetzes)

Topical Lexicon
Meaning and Function

Strong’s 2531 signals correspondence—linking two realities so that one clarifies, measures, or fulfills the other. The term often introduces (1) prophetic fulfillment, (2) paradigms for conduct, or (3) analogies that ground doctrine in God’s own character and acts.

Scope of Biblical Usage

Appearing 183 times, the word spans every major New Testament corpus: Gospels, Acts, Paul, General Epistles, Hebrews, and Revelation’s Johannine circle (1 John, 2 John, 3 John). Its range demonstrates a unifying thread: Scripture interprets Scripture, revelation mirrors revelation, and redeemed life mirrors divine life.

Linking Prophecy and Fulfilment

The Synoptic writers frequently employ the term to certify that Jesus’ ministry meets prophetic expectation.
Matthew 21:6; Mark 11:6; Luke 19:32 – the disciples obey “just as Jesus had directed,” echoing Zechariah’s king on a colt.
Matthew 28:6 – “He is not here; He has risen, just as He said,” sealing resurrection promise.
Luke 1:70 – God acted in Christ “just as He spoke through His holy prophets.”

The formula binds Old Testament promise to New Covenant realization, fortifying confidence in biblical continuity.

Modeling Christ

John’s Gospel turns the word into a bridge between Father, Son, and believer:
John 13:34 – “Love one another, just as I have loved you.”
John 15:9 – “Just as the Father has loved Me, I have also loved you.”
John 17:18 – “As You sent Me… I have also sent them.”

The correspondence is not mere imitation but participation; believers are drawn into Trinitarian life and mission.

Defining Love and Forgiveness

Paul wields the term to ground ethics in Christ’s redemptive act:
Ephesians 4:32 – “Forgive one another, just as God in Christ forgave you.”
Ephesians 5:25 – “Husbands, love your wives, just as Christ loved the church.”

Obligation flows from accomplished grace; duty is shaped by gospel reality.

Instructing the Church

Ecclesial order and ministry reflect apostolic precedent:
1 Corinthians 11:2 – “Maintain the traditions just as I delivered them.”
2 Thessalonians 3:1 – “Pray for us, that the word of the Lord may spread rapidly and be glorified, just as it was with you.”

The term safeguards continuity of doctrine and practice across congregations.

Grounding Soteriology

Paul cites Scripture “just as it is written” (Romans 1:17, 3:10) to anchor justification and anthropology. Salvation truth is not novel speculation but covenant testament verified by prior revelation.

Eschatological Parallels

Luke 17:26–30 – “Just as it was in the days of Noah… just as in the days of Lot… so will it be on the day the Son of Man is revealed.”

Historical judgments foreshadow the consummate one, urging watchfulness.

Representative Passages

Matthew 28:6; John 3:14; John 13:34; Acts 2:4; Romans 15:7; 1 Corinthians 15:49; Ephesians 5:2; 1 Peter 4:10; 1 John 3:3. Each text couples theological truth with corresponding response, forming a mosaic of gospel coherence.

Historical Reception

Early fathers read the term typologically. Justin Martyr highlighted Isaiah 53 fulfilled “even as” foretold. Irenaeus argued that the church’s life must mirror apostolic pattern “just as” Scripture records, defending orthodoxy against Gnostic innovation.

Application for Modern Ministry

1. Preaching: draw lines of continuity—promise to fulfillment, indicative to imperative.
2. Discipleship: present Christ’s example as both model and empowering source; we love, forgive, and serve “just as” we have been loved, forgiven, and served.
3. Apologetics: point to prophetic correspondences to commend biblical reliability.
4. Worship: shape prayers and songs to echo biblical patterns, aligning doxology with revealed truth.
5. Mission: send and support workers “just as” the Father sent the Son—incarnational, sacrificial, authoritative.

In every occurrence, the term presses the reader to see Scripture’s seamless fabric and to embody in life the same divine pattern it proclaims.
