The Greek word porneía, represented by G4202, is a significant term for harlotry. It appears 26 times across 25 unique verses in the Bible. Derived from πορνεύω, its definition includes adultery, incest, and, in a figurative sense, idolatry. The common English translation is fornication.
In scripture, G4202 is frequently included in lists of sins that originate from a corrupt heart, alongside acts like murders, thefts, and adulteries (Matthew 15:19, Mark 7:21). Believers are commanded to flee G5343 from fornication 1 Corinthians 6:18 and to abstain G567 from it as part of their sanctification G38 1 Thessalonians 4:3. The term carries legal weight in the context of marriage, as it is the only cause given for which a man may put away G630 his wife (Matthew 5:32, Matthew 19:9). Figuratively, it is used extensively in Revelation to describe the spiritual unfaithfulness and corrupting influence of Babylon Revelation 14:8.
Several related words help clarify the scope and context of G4202:
- G4203 porneúō (to act the harlot): This is the verb form of G4202, describing the action of committing fornication. It is used both literally and figuratively for practicing idolatry (1 Corinthians 6:18, Revelation 18:3).
- G4204 pórnē (a strumpet; figuratively, an idolater): This noun refers to the person, a harlot or whore, who engages in the act. In Revelation, the great whore G4204 is judged for corrupting the earth with her fornication G4202 Revelation 19:2.
- G167 akatharsía (impurity (the quality), physically or morally): Often listed alongside fornication, this term denotes a broader state of uncleanness. Both are presented as "works of the flesh" that believers must put away (Galatians 5:19, Colossians 3:5).
- G1495 eidōlolatreía (image-worship): This term for idolatry is the figurative counterpart to G4202. The definition of porneía explicitly includes idolatry, highlighting the biblical connection between sexual immorality and spiritual unfaithfulness Colossians 3:5.
The theological weight of G4202 is significant, touching on Christian ethics, ecclesiology, and eschatology.
- A Work of the Flesh: Fornication is consistently categorized as a product of the sinful nature, in opposition to a life of holiness. It is listed as a work of the flesh in Galatians 5:19 and is something from which believers must abstain G567 to live in a way that pleases God 1 Thessalonians 4:3.
- A Sin Against the Body: A unique theological point is made that while other sins are outside the body, "he that committeth fornication G4203 sinneth against his own body" 1 Corinthians 6:18. The body is not intended for G4202 but for the Lord G2962 1 Corinthians 6:13.
- Symbol of Spiritual Corruption: The concept of G4202 is used powerfully in Revelation as a symbol for idolatry and the corrupting power of worldly systems. Babylon is depicted holding a golden cup G4221 full of the "filthiness of her fornication," which has made all nations G1484 drunk (Revelation 17:4, Revelation 18:3).
In summary, G4202 extends far beyond a simple definition of a sexual act. It is a foundational term for understanding biblical morality, representing a serious violation of God's will for purity. It defines actions that defile the individual, harm the community, and, in its most profound figurative sense, symbolize the ultimate spiritual betrayal of idolatry. Its use demonstrates how scripture links physical purity with spiritual faithfulness.
