Today, the Church celebrates the significant feast of the Baptism of the Lord, marking a pivotal transition between the Christmas season and Ordinary Time. This feast not only concludes the Christmas season but also ushers in the public ministry of Jesus — a journey into His life and mission.

In his Summa Theologica, St Thomas Aquinas emphasises that Christ's baptism signifies the beginning of His ministry, during which He preached repentance and the Kingdom of God. Aquinas further highlights that Baptism is fundamentally a Sacrament of Faith, requiring faith from the recipient for it to be effective.

The Baptism of the Lord is narrated in the Gospels of Matthew, Mark, and Luke, with subtle references in the Gospel of John, underscoring its profound significance for Catholics.

What is the significance of the Baptism of the Lord?

According to St Gregory of Nazianzus, Jesus’ immersion in water symbolises the Light of Christ burying humanity’s sinful nature. Through the Spirit and water, a new creation is born. As Jesus rises from the waters, He lifts the world with Him. The heavens, once closed by Adam’s sin, are now opened, much like Paradise.

This symbolism also applies to us in baptism. By being immersed in the waters of baptism, we, too, become a new creation in the Light of Christ. This transformation fulfils the promise foretold in the Old Testament: “Prepare in the wilderness a way for the Lord; make a straight highway for our God across the desert.” Here, the prophet Isaiah portrays Jesus as the God who comes to save.

The imagery of Jesus' baptism draws a parallel between the new Exodus and the old. Just as the Israelites crossed the Red Sea to escape slavery and enter freedom, Jesus, through His immersion in the Jordan, liberates us from the bondage of sin, guiding us into the freedom of becoming children of the Light. The second reading affirms this, declaring that God’s grace is revealed through the cleansing waters of rebirth and the renewal of the Holy Spirit.

Today, we are invited to reflect on the meaning of our own baptism. While many of us were baptised as infants, this does not exempt us from reaffirming our faith today. Baptism is a Sacrament of Faith, drawing us into full participation in the life of Jesus. It marks the beginning of our journey as Christians and as members of the Body of Christ. Just as Jesus was launched into His public ministry through baptism, we, too, are called to a life of holiness and to proclaim the Kingdom of God.

I conclude with the words of St Basil the Great: “Our Lord made a covenant with us through baptism in order to give us eternal life.” Christ’s baptism illuminates the path to eternal life.
