1st Sunday of Advent — Cycle B: Readings, Gospel and Reflection for Mass
Today the Church marks the 1st Sunday of Advent, Cycle B, the opening moment of a new liturgical year. Advent invites believers to watch, pray, and prepare for Christ’s coming in history and at the end of time. The readings for this Sunday accompany the season’s vigil: Isaiah frames a cry for God to reveal his saving presence, Paul blesses the community with grace as they await the Lord, and Mark urges constant readiness for the unknown hour. The theme is not fear but hopeful expectancy: God has begun to rework our hearts, drawing us from exile toward home in God’s merciful plan. As the Church lights the Advent candle, the faithful are invited to awaken from complacency, practice daily conversion, and fix their gaze on the coming of the Lord, who draws near in word, sacrament, and service.
First Reading
Reference: Isaiah 63:16b-17; 64:1-8 (NABRE).
This passage records Israel’s cry for God’s immediate action. The speaker voices the paradox of God as Father yet distant due to exile, pleading for a dramatic intervention. The famous cry from Isaiah 64 calls, Oh, that you would rend the heavens and come down, so mountains would tremble before your presence. The text moves from lament to petition, remembering past mercies while confessing sin and longing for a renewal that only God can bring. Advent mood is set here: a holy readiness born of penitence, faith, and hope in the God who acts to save.
Responsorial Psalm
Psalm: Psalm 80; Antiphon: Let your face shine on us, O Lord.
The psalm expresses the people’s plea for mercy and for God to restore his presence among them. It invites us to seek the Lord in times of trial, to acknowledge our dependence on his saving power, and to trust the shepherding of God who sustains his people even in difficult days. The verses invite a posture of humility, repentance, and hopeful appeal to a merciful God who remembers his covenant.
Second Reading
Reference: 1 Corinthians 1:3-9 (NABRE).
The apostolic greeting to the Christians in Corinth carries a blessing of grace and peace from God the Father and the Lord Jesus Christ. Paul gives thanks for the grace already given to the community, recognizing that you are not lacking in any spiritual gift as you await the revelation of Jesus Christ. He reassures them of God’s faithfulness, who will sustain them to the end, making them steadfast in the grace that will carry them through trials and division toward unity in Christ. The passage centers on divine initiative and sustained fidelity, inviting believers to persevere in hope as they await the Lord’s return.
Gospel of the Day
Reference: Mark 13:33-37 (NABRE).
Gospel (paraphrase): Jesus speaks of vigilance and readiness for an unknown hour. He urges his followers to stay awake, keep watch, and pray, for they do not know when the time will come. The imagery of a household and its faithful servants awaiting the master’s return emphasizes a life of constant vigilance—not fear, but hopeful anticipation. Advent, then, becomes a season of spiritual awakening in which daily routines and choices are ordered toward prayer, service, and the sacraments. This call to alert discipleship invites us to live with integrity in the present moment, trusting that Christ will come again.
Exegesis: In the Olivet Discourse, Mark situates the disciples in a posture of expectant living that transcends fixed schedules. The command to stay awake highlights discipleship as ongoing conversion rather than a speculative countdown. The instruction complements the Advent themes found in Isaiah and Paul: longing for God’s saving presence and reliance on grace, while remaining vigilant as we await the Lord. For contemporary readers, the text challenges complacency and invites a steady rhythm of prayer, repentance, and active faith in times of uncertainty or hardship. The voice of Jesus remains a pastoral summons to interior watchfulness that bears fruit in concrete acts of love and fidelity.
Connection Between the Readings
The readings weave a unified Advent thread: a longing for God’s saving presence, a life grounded in grace as we await Christ’s return, and a vigilant stance that shapes daily living. Together they call for conversion of heart, trust in God’s faithfulness, and a lived hope that reaches from personal prayer to community witness during the season of expectation.
