### Core Meaning & Semantic Range
The Greek word **sýssōmos**, represented by `{{G4954}}`, is derived from the words σύν (meaning with or together) and σῶμα (meaning body). It appears only **1 time** in **1 verse** in the Bible. Its definition is "of a joint body," and it is used figuratively to describe a fellow-member of the Christian community.
### Biblical Occurrences & Contextual Analysis
The single biblical use of `{{G4954}}` is found in [[Ephesians 3:6]]. In this pivotal verse, the word describes the inclusion of the Gentiles into the church. The text explains that through the gospel, the Gentiles are not only to be fellow heirs and partakers of the promise in Christ, but are also to be "**of the same body**" with Jewish believers, signifying a complete and unified membership in a single spiritual entity.
### Related Words & Concepts
Several related words found in the same context illuminate the meaning of being "of the same body":
* `{{G4789}}` **synklēronómos** (a co-heir, i.e. (by analogy) participant in common): This word appears directly before `{{G4954}}` in [[Ephesians 3:6]], establishing that being members of the same body means sharing in the same inheritance in Christ.
* `{{G4830}}` **symmétochos** (a co-participant): Used immediately after `{{G4954}}`, this term reinforces the idea of shared status, specifying that members of the same body are also partakers of God's promise.
* `{{G1484}}` **éthnos** (a race... a foreign (non-Jewish) one... Gentile, heathen, nation, people): This word identifies the group, the Gentiles, who are being incorporated. The mystery of the gospel is that these nations are now included as part of the body [[Ephesians 3:6]].
### Theological Significance
The theological weight of `{{G4954}}` is significant despite its single appearance. It encapsulates a profound New Testament truth.
* **Unity in Christ:** The word itself, meaning "of a joint body," is a declaration of the unity between Jewish and Gentile believers. It conveys that in Christ, formerly separate peoples are joined into one new community.
* **Shared Status and Promise:** Its placement in [[Ephesians 3:6]] directly connects the concept of being one body with being "fellowheirs" `{{G4789}}` and "partakers" `{{G4830}}`. Membership in the body is inseparable from sharing in the divine promise.
* **The Revealed Mystery:** The inclusion of the Gentiles as "of the same body" is presented as a central component of the "mystery" of Christ that was preached to the nations ([[Ephesians 3:6]], [[Colossians 1:27]]).
### Summary
In summary, while `{{G4954}}` is used only once, it provides a crucial and concise definition for the nature of the church. The term **sýssōmos** illustrates that the gospel breaks down dividing walls, creating a single, unified body out of diverse peoples. It signifies a shared identity, a shared inheritance, and a shared promise for all who are in Christ, as powerfully stated in its sole context in [[Ephesians 3:6]].
