The Greek word kakós, represented by G2556, refers to that which is intrinsically worthless, depraved, or injurious. It appears 51 times across 46 unique verses in the Bible. Its meaning encompasses the subjective state of being depraved and the objective effect of being injurious or harmful. The base definition specifies that it refers to intrinsic worthlessness, whereas the word ponēros G4190 more properly refers to evil effects.
The semantic range of G2556 extends beyond mere objective harm to denote an inherent moral defect or corruption. It describes that which is fundamentally contrary to divine goodness and order, representing a qualitative assessment of intrinsic badness. This deep-seated perversion distinguishes G2556 from terms that might describe mere misfortune or difficulty, emphasizing a deliberate or inherent opposition to what is right and wholesome. It speaks to a profound brokenness, whether in character, thought, or deed, that is deemed reprehensible in the sight of God.
In scripture, G2556 is used to define the nature and source of sin. Jesus states that "from within, out of the heart of men, proceed evil thoughts" Mark 7:21. The word is consistently set in opposition to what is good. Believers are to overcome "evil with good" Romans 12:21 and be "wise unto that which is good, and simple concerning evil" Romans 16:19. It also describes individuals, such as the "evil servant" in a parable Matthew 24:48 or the "evil workers" Paul warns against Philippians 3:2. Furthermore, it can denote harm or injury, as when Alexander the coppersmith did Paul "much evil" 2 Timothy 4:14.
Beyond describing intrinsic depravity or specific individuals, G2556 often appears in the plural (kaká) to denote "evil things" or actions, encompassing a broad category of harmful deeds or desires. For example, the Israelites in the wilderness lusted after "evil things" 1 Corinthians 10:6, serving as a warning against similar desires. Paul also warns against "inventors of evil things" Romans 1:30, highlighting humanity's capacity to conceive and produce wickedness. In legal or judicial settings, the term signifies culpability, as when Pilate repeatedly asks what "evil" Jesus has done, finding "no evil" Luke 23:22, Mark 15:14, Matthew 27:23, or when the scribes declare "we find no evil in this man" concerning Paul Acts 23:9. This usage underscores a formal assessment of wrongdoing, demonstrating that G2556 can also refer to specific blameworthy acts or a lack thereof.
Several related words clarify the concept of evil and its opposite:
- G4190 ponērós (hurtful, i.e. evil): This word is distinguished from G2556 by referring to the hurtful effects or influence of evil, rather than its essential character. It is used alongside G2556 to describe a "noisome and grievous sore" Revelation 16:2.
- G18 agathós ("good"): As a direct antonym, this word is frequently used in contrast to G2556. Scripture commands believers to "overcome evil with good" Romans 12:21 and notes that God's judgment will assess whether one's deeds were "good or bad" 2 Corinthians 5:10.
- G2570 kalós (good... valuable or virtuous): This term for good often implies being valuable or honest. It is contrasted with G2556 in the context of spiritual maturity, where the senses are exercised "to discern both good and evil" Hebrews 5:14.
- G2560 kakōs (badly (physically or morally)): This adverbial form of G2556 describes actions or states. Jesus states that a master will "miserably destroy those wicked men" Matthew 21:41, using both the adverb and the adjective.
- G2549 kakía (malice, badness): This noun, derived directly from G2556, denotes the intrinsic depravity or moral baseness itself, often translated as "malice" or "wickedness." While G2556 describes the quality of being evil, G2549 refers to the evil disposition or inherent moral rottenness that gives rise to G2556 actions or states.
The theological significance of G2556 is profound, touching on core doctrines of sin and judgment.
- The Source of Sin: G2556 is directly linked to the depravity of the human heart. It is used to describe "evil thoughts" that lead to sins like "adulteries, fornications, murders" Mark 7:21. It is also listed among the things a believer must mortify, specifically as "evil concupiscence" Colossians 3:5.
- The Christian's Response: The word highlights the required response to evil. Believers are commanded not to render "evil for evil" 1 Peter 3:9 but to "eschew evil, and do good" 1 Peter 3:11.
- Divine Character and Judgment: God's nature is set apart from this kind of evil; He "cannot be tempted with evil, neither tempteth he any man" James 1:13. His judgment, however, addresses it, as "tribulation and anguish" are promised "upon every soul of man that doeth evil" Romans 2:9.
- Corrupting Influence: The word warns of the destructive power of evil associations. Scripture states that "evil communications corrupt good manners" 1 Corinthians 15:33, illustrating the objective harm G2556 can cause.
- The Inner Struggle with Evil: G2556 highlights the internal conflict experienced by even regenerate individuals. Paul laments, "For the good that I would I do not: but the evil which I would not, that I do" Romans 7:19, and further acknowledges, "when I would do good, evil is present with me" Romans 7:21. This demonstrates that G2556 is not merely an external force or action, but an ever-present inclination within the fallen human nature, necessitating continuous spiritual vigilance.
The Greek term G2556 kakós serves as a foundational descriptor for that which is intrinsically worthless, depraved, and injurious. It distinguishes itself from G4190 ponērós by emphasizing the inherent character of evil rather than merely its harmful effects. This intrinsic badness manifests from the "evil thoughts" of the human heart Mark 7:21 and extends to specific "evil things" lusted after 1 Corinthians 10:6 or "invented" Romans 1:30, encompassing actions that bring "much evil" to others 2 Timothy 4:14. It also characterizes individuals, such as the "evil servant" Matthew 24:48, and describes the very nature of sin that stands in direct opposition to all that is good G18 and virtuous G2570.
The theological weight of G2556 is profound, underscoring core doctrines of sin, human depravity, and divine judgment. It describes the "evil concupiscence" that believers are called to mortify Colossians 3:5 and defines the moral standard against which God's judgment is rendered Romans 2:9, for He cannot be tempted with G2556 James 1:13. The term further reveals the pervasive nature of evil, not only as an external corrupting influence—as "evil communications corrupt good manners" 1 Corinthians 15:33—but also as an internal struggle, where even the believer finds G2556 present within, hindering the desire to do good Romans 7:21.
Ultimately, G2556 articulates a comprehensive concept of moral badness, spanning from the deepest inclinations of the heart to outward harmful deeds. It establishes the stark biblical contrast between good and evil, calling believers to "overcome evil with good" Romans 12:21 and to develop the spiritual maturity to "discern both good and evil" Hebrews 5:14, thereby aligning their lives with the character of a holy God who is utterly separate from G2556.
