οἰκειακός
one of a family
Definition
The adjective οἰκειακός (oikeiakos) refers to someone belonging to a household or family unit. In its two New Testament occurrences, it describes the intimate, domestic sphere, encompassing both family members and household servants. In Matthew 10:25, Jesus uses it to describe the members of a household, saying a disciple should expect to be treated like his teacher and a servant like his master. In Matthew 10:36, the word takes on a more specific and negative connotation, where Jesus warns that a person's 'household members' (οἰκειακοὶ) will become their enemies, highlighting the painful betrayal that can occur within the closest relational circles.
Biblical Usage
This word is used only twice in the New Testament, both times in the Gospel of Matthew (Matthew 10:25, 10:36) within Jesus's instructions to his disciples. It appears in contexts discussing loyalty, persecution, and the cost of discipleship. The usage pattern shows a progression from a general, neutral term for household affiliates (Matthew 10:25) to a specific term for those who become adversaries from within one's own home (Matthew 10:36), directly quoting from the prophecy in Micah 7:6.
Etymology
Derived from the noun οἰκία (oikia, G3614), meaning 'house' or 'household.' The suffix -ακός forms an adjective meaning 'belonging to' or 'pertaining to.' Thus, οἰκειακός literally means 'household-related' or 'domestic.' It is a more specific term than the related οἰκεῖος (oikeios, G3609), which can also mean 'one of the household' but carries a stronger connotation of kinship or close belonging.
Semantic Range
This word is theologically significant as it underscores the radical nature of discipleship taught by Jesus. It reveals that following Christ can create divisions in the most foundational human institution—the family (Matthew 10:34-36). Understanding this Greek term enriches the reading of these passages by clarifying that the conflict Jesus predicts is not with distant strangers but with one's own 'household members,' emphasizing the profound personal cost and the supreme loyalty owed to Christ above all earthly ties.
In the first-century Greco-Roman world, the 'household' (οἰκία) was the central social and economic unit, typically including not only immediate blood relatives but also extended family, slaves, and hired workers. Therefore, οἰκειακός would be understood to encompass this entire domestic community. This cultural context makes Jesus's warning in Matthew 10:36 especially jarring, as it predicts the fracturing of this fundamental, secure social structure due to allegiance to him.
οἰκεῖος (oikeios, G3609) — A closer relative or member of the household, often with a stronger emphasis on kinship. οἰκέτης (oiketēs, G3610) — A household servant or domestic slave, a more specific term for one role within the οἰκειακός.
