What does Jesus mean by “not that which goeth into the mouth defileth a man”?

Jesus is saying that the food we eat, and whether our hands are ritually washed or not, does not make us spiritually unclean before God. What goes into the mouth passes through the body and is removed. It does not touch the heart, where our desires and motives live. He is correcting the idea that outward, physical things like certain foods or washing rules are what make a person right or wrong with God. Instead, He points to the heart as the real source of defilement.

Why were the Pharisees offended by Jesus’ teaching in this passage?

The Pharisees were offended because Jesus’ words cut across the traditions and rules they cared about and taught others to follow. They put great weight on rituals like hand-washing and dietary customs as marks of holiness. When Jesus said that what goes into the mouth does not defile a person, He was challenging their whole way of thinking about purity and religion. His teaching exposed their focus on the outside while ignoring the heart, so they felt threatened and insulted rather than corrected.

Why does Jesus call the Pharisees “blind leaders of the blind”?

Jesus calls them blind because they do not really see or understand God’s way, even though they claim to guide others. They are blind to the fact that the heart is the real issue, not outward rituals. When such people lead others, it is like a blind person leading another blind person down a road. Both are in danger and will fall into a ditch. This is a warning not to follow teachers who ignore or twist God’s truth, no matter how respected they may appear.

What does Jesus teach about the heart in this passage?

Jesus teaches that the heart is the source of the sins that truly defile a person. He says that evil thoughts, murders, adulteries, sexual sins, thefts, lying in court, and speaking against God all come from within. These do not come from food or from things outside us, but from our own inner desires and thoughts. This shows that we need more than clean hands or good habits. We need changed hearts, because our words and actions flow out of what is inside.

Why does Jesus say eating with unwashed hands does not defile a person?

Jesus says this because such washing is only about outward cleanliness and human tradition, not about the state of the soul before God. The disciples were worried about the religious rules taught by the Pharisees, who treated these washings as very important. Jesus explains that food and ordinary dirt pass through the body and do not touch the heart. So failing to keep such rituals does not make someone unclean in God’s sight. What really matters is whether the heart is full of love for God or full of sin.

How can this teaching about what defiles a person apply to life today?

This teaching reminds us not to rest in outward religious habits while ignoring what is going on inside us. It is possible to go to services, say prayers, and keep certain traditions while our hearts still hold bitterness, lust, greed, or dishonesty. Jesus calls us to watch our thoughts, words, and actions, because these show what is in our hearts. Today this means asking God to search our hearts, confessing sin honestly, and seeking His help to change from the inside, not just cleaning up the surface.

Why did Peter ask Jesus to explain this parable, and what does that show?

Peter asked for an explanation because he and the other disciples were still shaped by the same ideas about purity that many in their culture had. They did not at once grasp that Jesus was shifting the focus from food and rituals to the heart. Jesus gently rebukes them for being slow to understand after being with Him for so long. This shows that even close followers can struggle to let go of old ways of thinking. It also shows Jesus’ patience as He keeps teaching them more clearly.

Matt.15.10

Matthew 15:10

Q: What does “every plant, which my heavenly Father hath not planted, shall be rooted up” mean?

Jesus uses a picture of plants to talk about people and teachings. A plant that the Father has not planted is something that does not truly come from God, even if it looks religious. He is saying that false teachers and the systems they build will not last. In time, God will remove what He has not planted. This warns His followers not to be shaken when proud leaders reject the truth, and not to assume that every religious group or tradition is approved by God just because it looks established.

KJV Jesus

And he called the multitude, and said unto them, Hear, and understand:

What Defiles a Man

And he called the multitude, and said unto them, Hear, and understand:

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

Then came his disciples, and said unto him, Knowest thou that the Pharisees were offended, after they heard this saying?

But he answered and said, Every plant, which my heavenly Father hath not planted, shall be rooted up.

Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.

Then answered Peter and said unto him, Declare unto us this parable.

And Jesus said, Are ye also yet without understanding?

Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught?

But those things which proceed out of the mouth come forth from the heart; and they defile the man.

For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:

These are the things which defile a man: but to eat with unwashen hands defileth not a man.
