Thayer's Greek Lexicon
STRONGS NT 4954: σύσσωμος

σύσσωμος (L T Tr WH συνσωμος (cf. σύν, II. at the end)), συσσωμον (σύν and σῶμα), belonging to the same body (i. e. metaphorically, to the same church) (R. V. fellow-members of the body): Ephesians 3:6. (Ecclesiastical writings.)

Topical Lexicon
Biblical Setting

The word σύσσωμα appears once, in Ephesians 3:6, within Paul’s disclosure of the “mystery” now made known: “This mystery is that through the gospel the Gentiles are fellow heirs, fellow members of the body, and fellow partakers of the promise in Christ Jesus”. Positioned between “fellow heirs” (συγκληρονόμα) and “fellow partakers” (συμμέτοχα), σύσσωμα highlights corporate oneness. The letter had already presented Christ as Head over His church-body (Ephesians 1:22-23) and reconciler of both Jew and Gentile “in one body” (Ephesians 2:16). Paul now names Gentile believers as integral limbs within that very body.

The Mystery Revealed in Christ

Old-covenant Scriptures hinted that the nations would share Abraham’s blessing (Genesis 12:3; Isaiah 49:6), yet the mechanism remained veiled. In Christ, barriers of covenantal distinction met their end (Ephesians 2:14-15). The single occurrence of σύσσωμα therefore signals a watershed revelation: full incorporation of non-Jews without conversion to Judaism. The term conveys more than proximity; it declares organic union. Just as limbs cannot exist apart from the body, so no believer—Jewish or Gentile—exists outside the one new humanity formed in Christ.

Unity of Jews and Gentiles

The temple image in Ephesians 2:19-22 (one household, one holy temple) and the body metaphor of 4:4 (one body, one Spirit) converge in σύσσωμα. Unity is not merely cooperative; it is ontological. Therefore, ethnic, cultural, and social divides lose ultimate significance. The same indwelling Spirit (Ephesians 2:18) binds every believer to Christ and to one another.

Ecclesiological Implications

1. Equality of membership: No “outer court” remains for Gentiles. All share Christ’s headship, gifts, and inheritance (Romans 8:17).
2. Interdependence: 1 Corinthians 12:12-27 expands the body motif. Diversity of function enriches, never fractures, unity.
3. Corporate witness: The manifold wisdom of God is displayed “to the rulers and authorities in the heavenly realms” through this unified body (Ephesians 3:10). The church’s very existence as σύσσωμα testifies to the triumph of the gospel.

Practical Ministry Applications

Pastoral leadership must:
• Guard against hierarchies built on ethnicity, class, or tradition (James 2:1-9).
• Cultivate mutual care, recognizing every member’s indispensable role (Ephesians 4:15-16).
• Embrace global missions as an extension of one body rather than patronage of a “sending” church to a “receiving” one (Philippians 1:5-7).

Historical Reception

Early church fathers employed the body metaphor against schismatics (e.g., Cyprian, “On the Unity of the Church”). The Reformers appealed to it when challenging clerical elitism. Modern ecumenical movements sometimes appeal to σύσσωμα, though fidelity to apostolic doctrine remains the biblical prerequisite for genuine unity (2 John 9-11).

Relation to Other Syn- Compounds in Ephesians

Paul’s triad (συγκληρονόμα, σύσσωμα, συμμέτοχα) underscores three inseparable privileges: inheritance, identity, and experience. Together they encapsulate the total salvation package granted to all in Christ. Neglect of any element—future hope, present belonging, or ongoing participation—diminishes the gospel’s scope.

Doctrinal Significance

• Christology: The glorified Christ is Head of a multi-ethnic body; exclusivist claims deny His finished work.
• Soteriology: Union with Christ unites believers with one another; justification therefore produces community.
• Eschatology: The consummated body will comprise “a multitude…from every nation” (Revelation 7:9), fulfilling the promise implicit in σύσσωμα.

Summary

Strong’s 4954 encapsulates the gospel’s power to create one new humanity in Christ. Though used only once, the term conveys a foundational New Testament reality: believers of every background are organically joined in a single body, sharing Christ’s life, promises, and mission.
