ἀποστασία

Core Meaning & Semantic Range

The Greek word apostasía, represented by G646, is a term for defection from truth. It appears 2 times across 2 unique verses in the Bible. Its core meaning describes a state of apostasy, which is translated as a "falling away" or an act to "forsake" established beliefs or practices.

Biblical Occurrences & Contextual Analysis

In the biblical narrative, G646 is used in two key contexts. It has a significant eschatological meaning, where a "falling away" is described as an event that must occur before the "man of sin" can be revealed 2 Thessalonians 2:3. The term is also used in a more immediate context, where Paul is accused of teaching Jews among the Gentiles to forsake Moses by abandoning core customs like circumcision Acts 21:21.

Related Words & Concepts

Several related words help clarify the nature of this defection:

• G1818 exapatáō (to seduce wholly): This word for deception is used to warn believers not to be beguiled, as the "falling away" is something people can be led into through deceit 2 Thessalonians 2:3.
• G1321 didáskō (to teach): Apostasy is presented as something that can be taught. Paul was accused of teaching all the Jews among the Gentiles to forsake Moses Acts 21:21.
• G266 hamartía (a sin): The great "falling away" is directly linked to the revelation of the "man of sin," connecting the act of apostasy with a state of profound opposition to God 2 Thessalonians 2:3.

Theological Significance

The theological weight of G646 is significant and points to a grave spiritual condition.

• An Eschatological Prerequisite: The "falling away" is explicitly identified as a sign that must precede major end-time events, specifically the appearance of the "son of perdition" 2 Thessalonians 2:3.
• Abandonment of Established Truth: The accusation against Paul shows that apostasy was understood as encouraging others to abandon foundational religious laws and customs delivered by figures like Moses Acts 21:21.
• Connection to Deception and Perdition: The concept is closely tied to being deceived and is linked with the "man of sin" and the "son of perdition," highlighting its destructive nature 2 Thessalonians 2:3.

Summary

In summary, G646 is a potent term that signifies a deliberate defection from truth. It is not a passive drifting but an active "falling away" or an instruction to "forsake" established foundations. Its use in scripture points to both a specific, prophetic event preceding the end and a general act of abandoning divine teaching, always with severe spiritual consequences.
