Core Meaning & Semantic Range

The Greek word moichós, represented by G3432, defines a male paramour or, figuratively, an apostate. It appears 4 times across 4 unique verses in the Bible. The term is used to identify a man engaged in adultery, but it also carries a deeper, figurative meaning related to spiritual unfaithfulness to God.

Biblical Occurrences & Contextual Analysis

In its scriptural occurrences, G3432 is consistently found in lists of behaviors that are contrary to God's law. It is used to describe those who will not inherit the kingdom of God, alongside fornicators and idolaters 1 Corinthians 6:9. In a self-righteous prayer, a Pharisee thanks God that he is not an adulterer, illustrating how the term was recognized as a significant sin Luke 18:11. The term is also used figuratively in James 4:4, where "adulterers and adulteresses" describes those whose friendship with the world makes them enemies of God. In Hebrews 13:4, the word is used to warn that God will judge adulterers and whoremongers, contrasting this with the honor of an undefiled marriage.

Related Words & Concepts

Several related words provide a broader context for the sin of adultery and unrighteousness:

  • G3428 moichalís (an adulteress): This is the female counterpart to G3432, as seen in their joint usage in James 4:4. It is also used figuratively to describe a "sinful generation" Mark 8:38.
  • G4205 pórnos (fornicator, whoremonger): This term for a male prostitute or debauchee is frequently listed alongside adulterers, such as in the warning that the unrighteous will not inherit God's kingdom 1 Corinthians 6:9 and will face judgment Hebrews 13:4.
  • G733 arsenokoítēs (abuser of self with mankind): This word for a sodomite appears in the same list of grave sins as adulterers in 1 Corinthians 6:9, highlighting it as another behavior that excludes one from the kingdom of God.
  • G94 ádikos (unjust, unrighteous): This serves as a broader category of sin. In 1 Corinthians 6:9, adulterers are listed as an example of the unrighteous who will not inherit God's kingdom.

Theological Significance

The theological weight of G3432 is significant, highlighting key principles of faithfulness and judgment.

  • Exclusion from the Kingdom: The term is explicitly used to define a lifestyle that is incompatible with inheriting the kingdom of God, as stated in the apostolic warning in 1 Corinthians 6:9.
  • Spiritual Apostasy: The word's figurative use extends the concept of infidelity from a marital covenant to a spiritual one. Being a friend of the world is equated with being an adulterer against God James 4:4.
  • Divine Judgment: Scripture is clear that the behavior of an adulterer is subject to God's judgment, contrasting the sanctity of marriage with actions that will be explicitly judged Hebrews 13:4.
  • Categorical Unrighteousness: Being an adulterer is presented as a clear form of unrighteousness, as shown when the Pharisee lists it with being unjust Luke 18:11.

Summary

In summary, G3432 is a potent term that denotes both literal and spiritual unfaithfulness. While its direct meaning refers to a man who violates a marriage covenant, its scriptural application expands to include anyone who is unfaithful to their covenant with God. Its consistent placement in lists of sins that result in divine judgment and exclusion from God's kingdom underscores its severity in biblical ethics.
