This verse in the King James

King James wording
Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.

The verse places the stain, or cleanness, not only in what is encountered, but in the mind and conscience of the one encountering it.

Purity is not located only in the things around you; the verse connects it to the condition from which you receive them. When defilement and distrust take hold, nothing seems pure, because the stain reaches both mind and conscience. What you discern and what you carry within are bound together.

WHAT THIS UNDOES

The lie that sorting the world into clean and unclean things can leave your own mind and conscience untouched.

καθαροῖς

katharois

GROWS FROM

καθαρ-

kathar-

Clean, pure, free from contamination.

The word for “pure” belongs to the same family as “to cleanse” and “cleansing,” holding a clean state and the removal of stain together. The verse sets this cleanness beside the inner person, whose mind and conscience are named as defiled.

ALSO GROWS

katharizō: to cleanse, make clean

καθαρίζω

The cleansing verb shows the action related to the state called pure; the verse’s contrast turns on whether cleanness or stain is present.

katharismos: cleansing, purification

καθαρισμός

This noun names the process of cleansing, keeping the idea of purity connected to what is removed.

μεμιαμμένοις

memiammenois

GROWS FROM

μιαν-

mian-

The word family of ⁨μιαίνω⁩ (miainō): to stain, pollute, or defile.

“stained” in this verse is memiammenois. The verse repeats this verb family when it says the mind and conscience are defiled. The stain reaches the faculties by which a person thinks and discerns; it is not confined to an outside object.

ALSO GROWS

miasma: pollution, a defiling stain

μίασμα

This branch gives the stain a name, making visible the pollution implied by being defiled.

miasmos: defilement, pollution

μιασμός

This branch names the condition or act of pollution that the verse says reaches mind and conscience.

ἀπίστοις

apistois

GROWS FROM

πιστ-

pist-

Trust, confidence, and the quality of being firm or reliable.

“those who do not trust” in this verse is apistois. The negative form means “without trust,” and Titus places it alongside defilement. The word points to a stance of distrust, not simply a lack of information.

ALSO GROWS

pistis: trust, confidence

πίστις

The positive form clarifies what is absent in “unbelieving”: trust.

pisteuō: to trust, believe, or entrust oneself

πιστεύω

This verb shows trust as reliance, a way of receiving rather than merely knowing information.

pistos: firm, steady, reliable

πιστός

This related word carries the sense of steadiness that stands opposite to being without trust.

Scripture links cleanness and defilement to the inner condition of a person, not simply to the objects around them.

Create in me a clean heart, O God, and renew a steady breath within me.
Psalm 51:10 · SDVThe plea locates cleanness in the heart, matching Titus’s focus on the inner condition.
There is nothing from outside a man, entering into him, that can make him common. But the things coming out of a man, those are the things that make the man common.
Mark 7:15 · SDVJesus locates defilement in what emerges from within, echoing Titus’s placement of the stain in mind and conscience.
I know, and I am persuaded by the Lord Jesus, that nothing is unclean through itself. But to the one who counts anything unclean, to that one it is unclean.
Romans 14:14 · SDVThis verse likewise connects what is received as clean or unclean with the person who regards it.
Already you are clean through the word which I have spoken to you.
John 15:3 · SDV

John uses the same Greek word family behind “pure” when Jesus calls the disciples “clean.” Titus names the mind and conscience as places where defilement is present; John shows cleanness received through the spoken word.
