ἀφορίζω

I rail off, separate, place apart

Definition

The verb ἀφορίζω means to separate, set apart, or mark off as distinct. In the New Testament, it carries both a negative sense of exclusion and a positive sense of divine appointment. For example, it describes the separation of the wicked from the righteous at the final judgment (Matthew 13:49, 25:32) and the social ostracism of Jesus's followers (Luke 6:22). Positively, it denotes being specially set apart by God for a purpose, as with Paul being 'set apart' for the gospel (Romans 1:1) and the Holy Spirit setting apart Barnabas and Saul for missionary work (Acts 13:2).

Biblical Usage

ἀφορίζω is used nine times in the New Testament, appearing in Gospels, Acts, and Epistles. Its usage patterns show a clear divide: in the Gospels of Matthew and Luke, it describes a judicial or social separation, often with a negative connotation of division. In Acts and the Pauline letters, it takes on a positive, sacred meaning of being specially appointed or consecrated by God for service. Key examples include Acts 13:2 for divine commissioning and 2 Corinthians 6:17, which quotes the Old Testament to command believers to be separate from unbelievers.

Etymology

Derived from the preposition ἀπό (apo, meaning 'from') and the verb ὁρίζω (horizō, meaning 'to mark out a boundary' or 'to determine'). The compound thus literally means 'to mark off from' or 'to set boundaries from.' This root meaning of creating a distinction or separation is consistent throughout its biblical usage. The related noun ὅρος (horos) means 'boundary.'

Semantic Range

This word is theologically significant as it captures the biblical theme of holiness—being set apart by and for God. It underscores God's sovereign choice in calling individuals like Paul (Galatians 1:15) and the collective call for the church to be distinct from the world (2 Corinthians 6:17). Understanding this Greek term enriches reading by highlighting that Christian separation is not merely negative isolation but a positive, purposeful consecration for God's mission.

In the Greco-Roman world, the idea of separation or setting apart was common in religious contexts, where people or objects were dedicated to a deity. The Jewish background also heavily informs this term, reflecting concepts of ritual purity, the separation of Israel as a holy nation, and the prophetic calls to come out from among pagans. The negative social separation experienced by early Christians (Luke 6:22) would have been a severe form of ostracism in a culture valuing community honor and belonging.

χωρίζω (chōrizō, G5563) — emphasizes a physical or relational parting, like divorce or distance. διακρίνω (diakrinō, G1252) — focuses on making a judgment or distinction between things, often in a discerning sense. ἁγιάζω (hagiazō, G37) — means to make holy or sanctify, emphasizing the resulting state of purity rather than the act of separation itself.
