A frequent misinterpretation is viewing this as a blanket endorsement for unrestricted eating or disregard for physical health and bodily stewardship, ignoring that the context addresses ceremonial defilement under Jewish law rather than nutritional consequences or New Testament calls to moderation; another error is reducing it to mere speech control, overlooking the passage's expansion to heart-sourced sins like murder, adultery, and theft that truly defile.
Matthew 15:11
King James Version (1769)
11 Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
Jesus teaches that true defilement is not caused by what enters the mouth, such as food, but by what proceeds from it, revealing the sinful condition of the heart; this shifts emphasis from external rituals like ceremonial washing to internal moral purity, where evil thoughts, words, and actions originating from within a person make one unclean before God.
