Pope Leo XIV granted a plenary indulgence for the 100th World Mission Sunday, observed on October 18, 2026. The occasion marks a century since Pope Pius XI established the annual celebration, held this year under the theme “One in Christ, United in Mission.”
The Apostolic Penitentiary’s decree says the indulgence may be obtained under the usual conditions: sacramental confession, Eucharistic Communion, and prayer for the Pope’s intentions. The faithful are also asked to pray the Rosary with the Pope for the spread of the Gospel worldwide.
At the Angelus, Leo invited Catholics to reflect on a century of missionary history and pray that the Church remain faithful to the risen Jesus’ command to proclaim the good news to all creation.
In his message for the anniversary, released on January 25, Leo called on the Church to continue its missionary work with joy and zeal, emphasizing hearts united in Christ, reconciled communities, and generous cooperation. He described union with Christ as central to Christian life and said the Church’s mission includes renewing spiritual and fraternal unity among its members.
The Pope also warned that conflict, polarization, misunderstanding, and distrust—when present within Church communities—can weaken their witness. He said proclaiming the Gospel requires reconciled hearts and communion, and is a collective, communal, and synodal undertaking.
Indulgences connect ecclesial communion with missionary discipleship
Indulgences connect ecclesial communion with missionary discipleship because they make visible that Christian life is shared: sin harms the whole Church, while holiness and prayer can help others. An indulgence is not a substitute for repentance or a way to avoid conversion; it concerns the temporal consequences of sins whose guilt has already been forgiven, and calls for genuine dispositions of love of God and rejection of sin.
In seeking an indulgence, the faithful rely not on their own power but on Christ’s redemption and the Church’s communion of saints. That reliance can turn concern for one’s own spiritual healing outward: the Church teaches that the fruits of Christ’s redemption are shared, and that concern for another’s salvation belongs to the truth of this communion.
This is a missionary logic. Pope Francis teaches that the Church’s mission becomes more effective as communion deepens, and that encounter with Christ leads believers to encounter others and become involved in evangelization. Thus indulgences do not themselves constitute evangelization, but, rightly understood, they form disciples in conversion, charity, and solidarity—the dispositions from which missionary witness grows.
