“Unless your righteousness exceeds that of the Scribes and Pharisees, you will never enter the Kingdom of Heaven” (Mt 5:17,20). But what do this “fullness” of Christ’s Law and this “superior” justice that he demands consist in?Jesus explains it with a series of antitheses between the old commandments and his new way of propounding them. He begins each time: “You have heard that it was said to the men of old…”, and then he asserts: “but I say to you”…. (…).And he does this six times. This manner of speaking made a great impression on the people, who were shocked, because those words: “I say to you” were equivalent to claiming the actual authority of God, the source of the Law. The newness of Jesus consists essentially in the fact that he himself “fulfils” the commandments with the love of God, with the power of the Holy Spirit who dwells within him. And we, through faith in Christ, can open ourselves to the action of the Holy Spirit who makes us capable of living divine love.So it is that every precept becomes true as a requirement of love, and all join in a single commandment: love God with all your heart and love your neighbour as yourself.
