The scribe said to him, "Well said, teacher. You are right in saying, He is One and there is no other than he. And to love him with all your heart, with all your understanding, with all your strength, and to love your neighbor as yourself is worth more than all burnt offerings and sacrifices." And when Jesus saw that he answered with understanding, he said to him, "You are not far from the Kingdom of God."
Today we have the joy of tumbling, at long last, with a sensible scribe. There is nothing healthier than to agree with Christ: "You shall love the Lord your God with all your heart, and love your neighbor as yourself".
—On the Cross, Jesus put "Substance" to this precept.
