7:14-23 Jesus’ second argument against the Pharisees was a proverb that Jesus told the crowd. Later, in the privacy of a home, Jesus explained it to his disciples (7:17-23). It concerns moral distinctions about eating. Eating affects the digestive system, but moral issues involve the heart. The heart is a metaphor for the seat of moral decision making. How a person eats (with clean or unclean hands) or what a person eats (clean or unclean food) affects only the digestive tract, so it has no bearing on the moral issues of the soul. To help his later readers understand the implications of Jesus’ teaching, Mark adds the interpretive comment By saying this, he declared that every kind of food is acceptable in God’s eyes. In the apostolic church, Peter and Paul were instrumental in bringing this implication to light (see Acts 10:1–11:18; Rom 14:14; 1 Cor 8:8; Gal 2:11-21).
