Catholics around the world unite in prayer each day through the same cycle of Scripture readings. Published by the United States Conference of Catholic Bishops (USCCB) for use in the liturgical calendar, the “daily readings” center the faithful on the Word of God.
The Second Vatican Council highlights the importance of this practice, teaching that in the sacred books, "the Father who is in heaven meets His children with great love and speaks with them" (Dei Verbum, no. 21).
This encounter is intended to move beyond personal prayer; Scripture forms disciples, who are then sent forth to live the mission of the Church. The following sections explore how daily engagement with the Word sustains the Church's universal mission.
Catholic readings of the day are the select Scripture passages assigned to each day of the liturgical year. In the United States, they follow the official Liturgical Calendar for the Dioceses of the United States of America and are drawn from the Lectionary for Mass approved for use in those dioceses.
Every Mass includes at least two readings, one of which is always from the Gospels, along with a responsorial psalm or canticle (USCCB, Liturgy). On Sundays and solemnities, three readings are assigned — from a Prophet, an Apostle, and a Gospel — so that the faithful hear the continuity of God's work of salvation across both the Old and New Testaments. During the Easter season, the first reading is taken from the Acts of the Apostles rather than the Old Testament (General Instruction of the Roman Missal, no. 357).
Because these texts come from the approved Lectionary, a Catholic in a small rural parish and a Catholic in a downtown cathedral hear the same proclamation on the same day. That shared experience of sacred Scripture is one of the most tangible expressions of the Church's unity.
The Second Vatican Council taught that only by the light of faith and by meditation on the word of God can a person always and everywhere recognize God, seek His will in every event, and see Christ in everyone, whether relative or stranger (Apostolicam Actuositatem, no. 4). Missionary zeal, in other words, begins with an interior awareness that takes root through the readings of the Mass.
This interior awareness is just the beginning. The Council reminds us that the Word of God is living and dynamic. In Ad Gentes, a pivotal Vatican II document, the fathers of the Council use the imagery of a seed to illustrate how the Word—when nurtured in the "good ground" of our hearts—inevitably seeks expression (Ad Gentes, no. 22). What is received in prayer is not meant to remain hidden; it is meant to grow and bear fruit as a visible witness.
Pope Leo XIV made this same connection just this year. Reflecting on the day’s Gospel at his Angelus address on June 21, 2026, he said that proclaiming the Gospel is, before anything else, “a sharing of a personal encounter” with Christ — echoing St. Thomas Aquinas’s own teaching that the preacher’s task is to pass on to others what has first been contemplated in prayer. The daily readings are where that contemplation begins.
And there is a warning attached. Quoting St. Jerome, the Second Vatican Council reminds the faithful that ignorance of the Scriptures is ignorance of Christ (Dei Verbum, no. 25). We cannot proclaim someone we do not know. Catholics come to know Christ well enough to want to share Him through sustained engagement with the daily readings.
The Council was not citing an abstract authority. St. Jerome, the fourth-century priest who gave the Church the Latin Vulgate, spent decades laboring in a cave near Bethlehem over the original Hebrew and Greek texts so that the faithful of every generation could read Scripture in their own tongue. His scholarship was itself a missionary act, undertaken so that the Word he loved could travel farther than he ever could.
The Second Vatican Council promoted widespread access to Sacred Scripture for all the Christian faithful (Dei Verbum, no. 22). It also entrusted to bishops the responsibility of ensuring those in their care receive suitable instruction in the right use of the Bible, especially the New Testament, and above all the Gospels (Dei Verbum, no. 25).
Therefore, it is insufficient simply to distribute copies of the Bible en masse. Bishops are called to help the faithful understand and internalize God’s word. Going well beyond surface-level understanding, the Church relies on its daily readings from the Sacred Scriptures to nourish her children and meet their deepest spiritual needs (Dei Verbum, no. 23).
This spiritual nourishment shapes preaching, catechesis, and formation across every diocese. The daily readings, then, are not simply published. They are taught, preached, and applied — and that work belongs to the bishop as teacher of his local Church.
For Catholics, sacred Scripture is inextricably linked to our missionary mandate. As Vatican II reiterated, the principal means of “planting the Church” is the preaching of the Gospel of Jesus Christ (Ad Gentes, no. 6). Schools, clinics, seminaries, and pastoral infrastructure all serve that proclamation. Through their support for The Pontifical Mission Societies, Catholics can participate directly in the pastoral formation and missionary outreach of local Churches worldwide. By sustaining these key activities, the faithful, along with bishops worldwide, ensure that the Gospel is proclaimed and the word of God is deeply rooted in every community.
St. John Paul II put the obligation plainly: “proclamation is the permanent priority of mission, and the Church cannot elude Christ's explicit mandate, nor deprive men and women of the Good News about their being loved and saved by God” (Redemptoris Missio, no. 44).
This is also where missionary work finds its confidence. A missionary knows that he is not proclaiming a human truth, but the word of God, which has an intrinsic and mysterious power of its own (Redemptoris Missio, no. 45). The message does not depend on the persuasiveness of the one carrying it.
The Council offered a simple rule for reading Scripture: let prayer accompany it, so that God and the reader may talk together. We speak to Him when we pray, and we hear Him when we read the divine words (Dei Verbum, no. 25).
That conversation is where mission stops being an abstraction. You do not need to travel to take part in it. You can begin by:
Reading the day's readings before Mass, so the proclamation meets a prepared heart
Meditating on a single verse rather than moving quickly through all the texts
Praying for missionaries and mission territories alongside the reading
Returning to the Gospel at the end of the day
Our regular, personal encounter with Scripture can become the seed of missionary work. Enlightened and spiritually nourished by the daily readings, Catholics in the United States are encouraged to share in the Church’s mission through their prayer, formation, and generosity.
Few people embodied that arc more visibly than Archbishop Fulton J. Sheen, who will be beatified on Sept. 24, 2026. For sixty years, Sheen anchored his priesthood in a daily Holy Hour before the Blessed Sacrament, which included a quiet reading of Scripture and which he called not a devotion but “a sharing in the work of redemption.” That same hour of prayer fed the homilies and broadcasts that reached tens of millions of Americans. And from 1950 to 1966, Archbishop Sheen served as National Director of the Society for the Propagation of the Faith — the U.S. branch of what is known today as The Pontifical Mission Societies — raising millions of dollars for missions overseas. The Word he received in silence became a mission he carried to an entire country.
The Pontifical Mission Societies exist at the nexus of these two realities: the Word received in prayer and the mission carried out in the world. Operating under the mandate of the Holy Father and in partnership with local bishops, TPMS helps ensure that communities receiving the Gospel have properly trained catechists to explain it, well-formed seminarians to preach it, and active parishes where it can take root.
The Word is given to be received. It is also given to be carried.
