Word Study

In depth

A plain-language study of molýnō — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Greek word molýnō, represented by G3435, means to soil or, figuratively, to defile. It appears 5 times across 3 unique verses in the Bible. Based on its root, likely from the word for "black," it conveys the idea of staining or contaminating something, particularly in a moral or spiritual sense.

Biblical Occurrences & Contextual Analysis

In its biblical usage, G3435 consistently refers to a state of spiritual impurity rather than physical dirtiness. In 1 Corinthians, it is used to describe how a person's conscience can be defiled. For those whose conscience is weak, eating food associated with an idol morally stains them 1 Corinthians 8:7. In the book of Revelation, the term is used to describe those who have maintained their spiritual purity. Some in the church of Sardis had not defiled their garments Revelation 3:4, while the 144,000 are described as those who were not defiled with women, as they are "virgins" Revelation 14:4.

Related Words & Concepts

Several related words help clarify the contexts in which this defilement occurs:

  • G4893 syneídēsis (moral consciousness:--conscience): This is the part of a person that can be defiled by actions perceived as sinful, as seen when a weak conscience is stained by eating food offered to idols 1 Corinthians 8:7.
  • G2440 himátion (a dress (inner or outer):--apparel, cloke, clothes, garment, raiment, robe, vesture): This is used symbolically to represent a person's spiritual state. To have undefiled garments signifies righteousness and worthiness Revelation 3:4.
  • G1494 eidōlóthyton (an image-sacrifice, i.e. part of an idolatrous offering:--(meat, thing that is) offered (in sacrifice, sacrificed) to (unto) idols): This is the object that can cause a weak conscience to become defiled, highlighting the polluting influence of idolatry 1 Corinthians 8:7.
  • G1497 eídōlon (an image (i.e. for worship); by implication, a heathen god, or (plural) the worship of such:--idol): This is the source of the defiling practice in 1 Corinthians, where a person's "conscience of the idol" leads to their defilement 1 Corinthians 8:7.

Theological Significance

The theological weight of G3435 centers on the nature of spiritual purity.

  • Internal Defilement: The term emphasizes that defilement is not merely an external act but an internal state. A weak conscience can be stained even by an action that others with stronger knowledge might consider permissible 1 Corinthians 8:7.
  • Symbolic Purity: The concept of undefiled garments illustrates that a person's actions and moral character create a spiritual "appearance" that determines their worthiness to "walk with" Christ Revelation 3:4.
  • Required Holiness: The usage in Revelation connects being undefiled with redemption and closeness to God. Those who follow the Lamb are marked by a purity that sets them apart Revelation 14:4.

Summary

In summary, G3435 is a specific term for moral and spiritual contamination. It illustrates that defilement can affect a believer's conscience through association with idolatry and that maintaining a state of purity, symbolized by clean garments, is a mark of worthiness and faithfulness. The word serves as a reminder that spiritual cleanliness is essential for fellowship with God.
