Psalm 46 (45 in the Septuagint and Vulgate numbering) is a hymn of confidence in God as refuge and strength, traditionally attributed to the sons of Korah. It belongs to a cluster of Zion psalms (46–48) that celebrate the security of the city where God dwells. Many scholars link its origins to the late eighth century BC, often associating it with the deliverance of Jerusalem from Sennacherib’s siege in 701 BC under Hezekiah, an event that resonates with the language of Isaiah. The psalm’s three stanzas (marked by Selah) move from cosmic upheaval to the quiet river that gladdens God’s city, then to the call to behold the Lord’s deeds. It became famous in Christian tradition as the basis of Luther’s “A Mighty Fortress Is Our God.”

The selected verses (2-3, 5-6, 8-9) with the response “The waters of a river give joy to God’s city, the holy place, the abode of the Most High” focus on unshakeable trust and the presence of God. God is refuge and strength, an ever-present help, so that the people need not fear even if the earth rocks and the mountains quake into the sea. A river’s waters give joy to God’s city; God is in her midst, so she cannot be shaken, and he will help her at dawn. The Lord of hosts is with them; the God of Jacob is their stronghold. They are invited to come and behold the awesome deeds he has done. Chaos yields to the serene presence of the Most High.

In the Roman Catholic Lectionary, these verses are appointed as the Responsorial Psalm for the Feast of the Dedication of the Lateran Basilica (9 November). The Lateran is the cathedral of the Bishop of Rome, “mother and head of all the churches.” The First Reading (Ezekiel 47:1-2, 8-9, 12) describes life-giving water flowing from the Temple. The Second Reading (1 Corinthians 3:9c-11, 16-17) declares that the Church is God’s temple, built on Christ, and that the Spirit dwells in believers. The Gospel (John 2:13-22) recounts the cleansing of the Temple and Jesus’ words about the temple of his body, raised in three days.

Psalm 46 unites these images. The river that gladdens God’s city echoes Ezekiel’s stream and anticipates the living water from Christ’s side. The city that cannot be shaken because God is in her midst becomes a figure of the Church, the living temple. For the assembly, the psalm turns the dedication of a building into a celebration of the people among whom God dwells. The response becomes both praise and promise: the waters of God’s presence continue to give joy to his city, and the Lord of hosts remains the stronghold of his people.
