+ Mk 7: 1-13
Now when the Pharisees with some scribes who had come from Jerusalem gathered around him,
they observed that some of his disciples ate their meals with unclean, that is, unwashed, hands.
(For the Pharisees and, in fact, all Jews, do not eat without carefully washing their hands, 2 keeping the tradition of the elders.
And on coming from the marketplace they do not eat without purifying themselves. And there are many other things that they have traditionally observed, the purification of cups and jugs and kettles (and beds).)
So the Pharisees and scribes questioned him, “Why do your disciples not follow the tradition of the elders 3 but instead eat a meal with unclean hands?”
He responded, “Well did Isaiah prophesy about you hypocrites, as it is written: ‘This people honors me with their lips, but their hearts are far from me;
In vain do they worship me, teaching as doctrines human precepts.’
You disregard God’s commandment but cling to human tradition.”
He went on to say, “How well you have set aside the commandment of God in order to uphold your tradition!
For Moses said, ‘Honor your father and your mother,’ and ‘Whoever curses father or mother shall die.’
Yet you say, ‘If a person says to father or mother, “Any support you might have had from me is qorban”‘ (meaning, dedicated to God),
you allow him to do nothing more for his father or mother.
You nullify the word of God in favor of your tradition that you have handed on. And you do many such things.”

Jesus said to his disciples: “Love one another even as I have loved you.”
2196 In response to the question about the first of the commandments, Jesus says: “The first is, ‘Hear, O Israel: The Lord our God, the Lord is one; and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.’ The second is this, ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”
The apostle St. Paul reminds us of this: “He who loves his neighbor has fulfilled the law. The commandments, ‘You shall not commit adultery, You shall not kill, You shall not steal, You shall not covet,’ and any other commandment, are summed up in this sentence, ‘You shall love your neighbor as yourself.’ Love does no wrong to a neighbor; therefore love is the fulfilling of the law.”
