On Saturday of the First Week of Lent our Church invites us to first read and reflect on a passage from the book of Exodus (12:37-49, 13:11-16) entitled "The Hebrews depart. The law of the Passover and of the firstborn". Our treasure, which follows, is from the pastoral constitution on the Church in the modern world of the Second Vatican Council.
Gaudium et spes ("Joys and Hopes"), the Pastoral Constitution on the Church in the Modern World, is one of the four constitutions resulting from the Second Vatican Council in 1965. It was the last and longest published document from the council and is the first constitution published by a Catholic ecumenical council to address the entire world. Gaudium et spes clarified and reoriented the role of the church's mission to people outside of the Catholic faith. It was the first time that the church took explicit responsibility for its role in the larger world. The constitution's creation was necessitated by fear of the irrelevance in the modern era due to its ignorance on problems that plague the modern world. The document represents an inner examination of the church by the council and features a response to problems affecting the modern world.
Gaudium et Spes can be summarized this way: The Church walks with humanity, affirming what is true and good in modern life, correcting what is disordered, and always pointing to Christ as the answer to the deepest questions of the human heart.
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.
