Titus 1:15 (KJV)

What does Titus 1:15 mean?

Titus 1:15 says that for people who are pure in heart, everything is clean to them, but for those who are corrupted and do not believe, nothing is clean—because their minds and consciences are themselves corrupted. This verse draws a sharp contrast between inner purity and inner corruption, showing that a person’s outlook and judgment are shaped by the condition of their heart.

Paul is writing to Titus, a young leader on the island of Crete, warning him about people who claim to know God but whose actions show otherwise. In this verse, Paul highlights that purity or corruption is not just about outward actions or rituals, but about what is inside a person—their mind and conscience. This teaching responds to false teachers who focused on external rules rather than true inner change.

The Greek behind Titus 1:15

• καθαρός (katharos, "pure"): This word means clean or pure, often referring to moral or spiritual purity. Paul uses it to describe those whose hearts and motives are sincere, not just outwardly clean.
• μιαίνω (miainō, "defiled"): This word means stained, polluted, or corrupted. Paul uses it to describe people whose inner life is tainted, so that nothing seems clean to them, no matter what they do.
• ἀπιστος (apistos, "unbelieving"): This word means not trusting or not having faith. Paul links unbelief with inner corruption, suggesting that lack of faith affects a person’s whole outlook.
• νοῦς (nous, "mind") and συνείδησις (syneidēsis, "conscience"): These words refer to a person’s thinking and moral awareness. Paul says even these inner faculties are corrupted in those who are defiled and unbelieving, so their judgment is affected at the deepest level.

Why Titus 1:15 matters

• Titus 1:15 clarifies that true purity is a matter of the heart and mind, not just following external rules or rituals, which was a major issue among some early teachers.
• This verse helps clear up the misunderstanding that certain foods or practices automatically make someone impure; instead, Paul points to the importance of inner character.
• The verse connects to the wider passage by exposing the root problem with false teachers: their lack of genuine faith and inner purity, which affects everything they do and teach.
