Psalm 25 (24 in the Septuagint and Vulgate numbering) is an acrostic lament and prayer for guidance, traditionally attributed to David. It is one of the alphabetical psalms (each verse beginning with successive letters of the Hebrew alphabet), suggesting it was composed for teaching or liturgical memorisation. Scholars generally date it to the post-exilic period (5th–4th century BC), though it draws on earlier wisdom and covenant traditions. The psalm reflects the experience of an individual (or the community) seeking God’s direction amid distress, confessing sin, and trusting in divine mercy. Its structure alternates between petition, confession of trust, and praise, making it a model of humble dependence on God.

The selected verses (4-5b, 6-7, 8-9) with the response “Remember your compassion, O Lord” form a heartfelt prayer for instruction and forgiveness. The psalmist asks the Lord to make known His ways, teach His paths, and guide him in truth, acknowledging God as the God of salvation. He pleads for God to remember His compassion and merciful love from of old, not the sins of his youth or transgressions, but to remember him according to His goodness. The psalm affirms that the Lord is good and upright, showing the way to sinners and guiding the humble in right judgement, teaching them His way. This creates a beautiful interplay of human need and divine character.

In the Lectionary, these verses are appointed as the Responsorial Psalm for the 26th Sunday in Ordinary Time, Year A. The readings emphasise God’s call to conversion, justice, and obedience. The First Reading (Ezekiel 18:25-28) stresses personal responsibility and the possibility of repentance; the Second Reading (Philippians 2:1-11) presents the humility and obedience of Christ; and the Gospel (Matthew 21:28-32) recounts the parable of the two sons, where the one who initially refuses but later obeys does the father’s will, illustrating that tax collectors and prostitutes enter the Kingdom ahead of the outwardly religious.

Psalm 25 complements these readings powerfully. Its prayer for guidance and plea for God to remember compassion rather than sins aligns with Ezekiel’s call to turn from wickedness and the Gospel’s emphasis on actual obedience over empty profession. The psalmist’s humility mirrors Christ’s self-emptying in Philippians. For the assembly, the psalm transforms Ordinary Time into a season of honest self-examination and hopeful conversion. It reminds believers that the same merciful Lord who teaches the humble continues to guide His people today. The response “Remember your compassion, O Lord” becomes a corporate prayer for the grace of repentance and the courage to change, inviting the faithful to trust in God’s goodness rather than their own righteousness. In this way, the psalm prepares hearts to respond generously to God’s call, as the second son ultimately did.
