The law was given through Moses, grace and truth came through Jesus Christ

On the Second Sunday of Lent our Church invites us to first read and reflect on a passage from the book of Exodus (13:17---14:9) entitled "The crossing of the Red Sea". Our treasure, which follows, is from a sermon by Saint Leo the Great, pope. Saint Leo became pope in the year 440. Saint Leo was a Roman aristocrat, and was the first pope to have been called "the Great". Saint Leo is known as one of the best administrative popes of the ancient Church. His work branched into many areas of the church, indicative of his notion of the pope's total responsibility for the flock of Christ. In the 96 sermons which have come down to us, we find Leo stressing the virtues of almsgiving, fasting, and prayer, and expounding Catholic doctrine with clarity and conciseness, particularly the dogma of the Incarnation. Leo is perhaps best known for having met Attila the Hun in 452 and having persuaded him to turn back from his invasion of Italy. The Book of Exodus, the second book of the Pentateuch, takes its name from a Greek word meaning "departure," highlighting the defining event of Israel's history: the Lord's deliverance of His people from slavery in Egypt. Its Hebrew title, Shemoth — "Names" — comes from its opening line, reminding us that God's saving work unfolds within real history, among real persons whom He knows and calls. Exodus continues the sacred story where Genesis ends. The descendants of Jacob, once welcomed in Egypt, find themselves oppressed and enslaved. Into this suffering, God reveals Himself not as distant, but as the One who hears the cry of His people. Through Moses, He performs mighty works, freeing Israel and leading them through the Red Sea — an event the Church has long recognized as a powerful foreshadowing of Baptism and redemption. Yet liberation is only the beginning. At Mount Sinai, God establishes His covenant with Israel. The Law (torah) given through Moses is not merely a set of rules but the framework of a relationship. God saves first; then He teaches His people how to live in the freedom He has given. The moral, civil, and ritual laws form Israel into a holy nation, called to reflect God's own holiness before the world. A striking portion of Exodus is devoted to the tabernacle, the portable sanctuary where God chooses to dwell among His people. This reveals the deeper purpose of salvation: communion. God does not simply rescue Israel from something — He rescues them for something — life in His presence. Even when Israel falls into rebellion, we witness repentance, covenant renewal, and divine mercy. The book culminates with the construction of the tabernacle and the descent of the cloud, the visible sign of God's glorious presence. In Exodus, we see the foundations of Israel's identity: a people redeemed, covenanted, instructed, and indwelt by God. For Catholics, the book speaks not only of ancient history but of the enduring pattern of salvation: God delivers, God binds Himself to His people, God teaches, and God remains with them.
