Thus, they brought this matter to the Lord’s attention to seek clarification on His earlier statement.
The words spoken by the Lord had disturbed the Pharisees, who were accustomed to the necessity of ritual handwashing for spiritual cleanliness and interpreted Christ's words as undermining this law. They may have also been offended as Christ spoke directly to the people and challenged their authority with His teachings. In responding to their challenge, Christ labeled either the Pharisaical teachings—derivatives of human invention devoid of divine inspiration—or the Pharisees themselves as entities that should be uprooted. Although they served as leaders and teachers, they were not aligned with God's will and thus did not enjoy His care. As a result, they were destined for destruction. Consequently, He advised to disregard their teachings, warning that following them could lead to their downfall; alternatively, they should be left to their own devices.
After this, the Apostle Peter, representing the other disciples, requested clarification on the puzzling statements concerning what defiles a person through consumption versus what does not. The Lord explained clearly that the food entering the mouth symbolized sustenance, while the moral impurities signified by what comes out of the mouth referred to evil thoughts, desires, and intentions that spring from the heart. These latter aspects indicate the true moral condition of the human soul, while food, once ingested, passes through the body without affecting one's spirit.
