### Core Meaning & Semantic Range
The Greek word **kathēgētḗs**, represented by `{{G2519}}`, is defined as a guide or, figuratively, a teacher, and is translated as **master**. It is derived from a compound of κατά and ἡγέομαι. This specific term is rare, appearing only **3 times** across **2 unique verses** in the Bible, making its usage highly significant.
### Biblical Occurrences & Contextual Analysis
The word `{{G2519}}` is found exclusively in a direct teaching from Jesus. In a warning against the adoption of honorific titles, Jesus instructs his followers, "Neither be ye called **masters**: for one is your **Master**, even Christ" [[Matthew 23:10]]. This command directly reserves the title of **Master** `{{G2519}}` for Christ alone. The instruction is reinforced by the preceding verse, which contrasts the earthly title of "Rabbi" with the singular authority of the one **Master** [[Matthew 23:8]].
### Related Words & Concepts

* `{{G4461}}` **rhabbí**: Defined as "my master, i.e Rabbi, as an official title of honor," this term is what believers are told not to be called, directly contrasting it with the singular spiritual authority of Christ as the one **Master** [[Matthew 23:8]].
* `{{G5547}}` **Christós**: Meaning "anointed, i.e. the Messiah, an epithet of Jesus," this identifies the one who exclusively holds the title of **Master** `{{G2519}}`, as stated in both [[Matthew 23:8]] and [[Matthew 23:10]].

### Theological Significance
The theological weight of `{{G2519}}` is focused and powerful, establishing a core tenet of Christian faith.
* **Exclusive Headship of Christ:** The primary significance is the reservation of the title **Master** for Christ alone. The repetition in the passage emphasizes that no human should hold this position of ultimate spiritual guidance [[Matthew 23:10]].
* **A Community of Equals:** By forbidding titles like **Master** `{{G2519}}` and Rabbi `{{G4461}}`, the passage dismantles religious hierarchy among believers, placing them on equal footing as **brethren** `{{G80}}` under their one leader.
* **Christ as the Sole Guide:** The root meaning of `{{G2519}}` as a "guide" or "teacher" underscores Christ's role as the definitive source of truth and direction for his followers, distinguishing him from all other teachers.
### Summary

Its appearance in Matthew 23 serves as a foundational command that establishes Christ as the single, authoritative **Master** and guide for the church, defining his followers not by rank, but by their shared identity as **brethren** under his exclusive leadership.
