Then Jesus called the crowd together again, saying, “Hear my words, all of you, and take them to heart. What truly contaminates a person is not what he puts into his body, but what comes out. That’s what makes a person defiled.” When Jesus went back home and away from the crowd, his disciples acknowledged that they didn’t understand the meaning of the parable and asked him to explain it. He answered them, “Are you as dull as the rest? Don’t you understand that you are not defiled by what you eat? For the food you swallow doesn’t enter your heart, but goes into your stomach, only to pass out into the sewer.” (This means all foods are clean.) He added, “Words and deeds pollute a person, not food. Evil originates from inside a person. Coming out of a human heart are evil schemes, sexual immorality, theft, murder, adultery, greed, wickedness, treachery, debauchery, jealousy, slander, arrogance, and recklessness. All these corrupt things emerge from within and constantly pollute a person.”
