Matthew 15:11

Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.

Matthew 15:11 (KJV)

Context

Jesus spoke these words in a confrontation with Pharisees and scribes who criticized His disciples for eating without first performing the traditional ceremonial handwashing (Matthew 15:1-2). The religious leaders treated this custom as a matter of ritual purity, but Jesus used their accusation to correct a deeper misunderstanding about what truly makes a person unclean before God.

Meaning

The verse draws a clear contrast between what enters the mouth and what comes out of it. Food and drink, even when consumed without ceremonial washing, do not make a person spiritually defiled. Instead, Jesus teaches that defilement comes from what proceeds out of the mouth—the words a person speaks and the attitudes those words reveal. The Greek word translated “defile” (koinoō) means to make common or unclean, and in this context it points to moral and spiritual impurity rather than physical or ritual uncleanness.

Jesus’ statement challenges the Pharisaic emphasis on external observance. The Pharisees were concerned with outward traditions, but Jesus redirects attention to the heart, the source of a person’s speech and conduct. This is not a rejection of all ritual, but a reordering of priorities: inner transformation matters more than external compliance.

Biblical connections

Jesus expands this teaching in Matthew 15:17-20, explaining that evil thoughts, murders, adulteries, fornications, thefts, false witness, and blasphemies come from the heart and defile a person. This reinforces the principle that true purity is a matter of the inner life, not merely external actions. The same truth appears in Mark 7:19, where the Gospel writer notes that Jesus declared all foods clean, and in 1 Samuel 16:7, where God looks on the heart rather than outward appearance.

Application

This verse calls believers to examine their speech as a window into the heart. Words that tear down, deceive, or dishonor God reveal inner defilement that no amount of religious routine can cleanse. The remedy is not stricter external observance but a heart transformed by God’s grace. Christians are invited to ask the Spirit to purify their thoughts and intentions so that what comes out of the mouth reflects a heart submitted to Christ.

Reflection

Jesus, as the authoritative teacher, reinterprets the traditions of the elders and reveals that true purity is inward. This teaching was countercultural in His day, and it remains so in any age that prizes appearances over character. The verse invites honest self-examination: do our words reveal a heart that trusts in God, or one that relies on outward forms? Only God can change the heart, and He offers that transformation through His Son.
