For many, the Old Testament can be confusing, filled with laws, rituals, and prophecies that seem difficult to connect with the New Testament. Yet, Jesus’ words remind us that the Old Testament is not merely a relic of the past but an essential part of God’s divine plan. Furthermore, every law, prophecy, and detail, down to “the smallest letter or the smallest part of a letter,” finds its deepest meaning and completion in Christ. In a simplified way, the “Law and the Prophets” in the Old Testament can be summarized as moral laws, ceremonial laws, and prophetic teaching. The moral laws reflect God’s eternal truths of right and wrong, the ceremonial laws govern Israel’s worship and rituals, and the prophetic teaching calls the people to repentance, pointing to the coming Messiah. Together, these form the foundation of the Old Covenant, which is fulfilled in Christ, Who established the New and Eternal Covenant. Additionally, the Psalms and Wisdom literature enrich the Law and the Prophets, offering inspired prayers, meditations on God’s faithfulness, and practical guidance for virtuous living. Though it might be an arduous task to read through the entire Old Testament, those who do so with understanding discover the truth that everything finds its fulfillment in Christ. “Fulfillment” does not mean that Jesus altered or discarded the Old Testament; rather, He revealed its true and hidden meaning, bringing it to perfection. What the Old Testament could only foreshadow, Jesus accomplished, achieving the fullness of God’s plan. By analogy, consider an artist’s sketch that depicts a beautiful mountain range and sunset. The Old Testament is like that sketch—it provides the framework, details, and foreshadowing of something greater. In Christ, the sketch is brought to life, becoming reality through God’s creative act. While the sketch and the actual mountain range are the same scene, the reality is the perfect and complete expression of what the sketch anticipated. God, as the Divine Artist, first “sketched” what would come to be through the Law, Prophets, and Wisdom literature, and then brought it to fulfillment through Jesus’ Incarnation, Life, Death, and Resurrection. In today’s Gospel, after declaring that He came to fulfill the Law and the Prophets, Jesus provided three examples of how He brings the Old Testament moral law to its fulfillment. The commandment “You shall not kill” is deepened to include the interior sin of anger; “You shall not commit adultery” is expanded to include lust in the heart; and “Do not take a false oath” is elevated to a call for sincerity, honesty, and integrity in all one says and does. The Messiah then pours forth His grace, enabling the faithful to live in accord with this high calling. Though not included in today’s Gospel, Jesus also brings the ceremonial laws to fulfillment by becoming the Lamb of God, offering Himself as the definitive High Priest on the new altar of the Cross. Furthermore, our Lord fulfills the prophets by establishing the New Covenant in His blood, as seen in Isaiah’s vision of the Suffering Servant Who bears the sins of many (Isaiah 53), Jeremiah’s promise of the new covenant written on hearts (Jeremiah 31:31–34), and Micah’s prophecy of a ruler born in Bethlehem (Micah 5:2). Reflect today on God’s Eternal Law, established before the foundation of the world and brought to fulfillment in Christ. The human life of the Son of God is the center of time and eternity. Everything converges on Him, and new life flows from Him. Just as our Lord fulfills the Old Testament, He also is the only source of true fulfillment in our lives. Ponder His mission and renew your choice to accept His New Covenant, written on your heart by grace. Doing so is an exercise in Divine Wisdom, giving you a share in the new life of grace, made possible by His blood. Glorious Lawgiver and Messiah, Your Wisdom is perfect, eternal, and transforming. All things came to be through You and find their fulfillment in You. I thank You for the gift of Your Eternal Law and pray for the grace to live it to perfection, with the aid of Your saving grace. Jesus, I trust in You.
